BMW - THE ANNOYING HESITATION AND HOW TO FIX IT

You are ambling along in your lovely BMW and suddenly a gap open up and you want to accelerate to get into it - but all it does is groan and accelerates like a 116i pulling a trailer. Well, this is extremely annoying and has been the case since the 1990's!
This video explains why your BMW hesitates before accelerating - but much more importantly tells you a simple trick to stop it happening so you can release the full beans whenever you want it. Go on, you know you want to!

Tim, you are gold! I was hesitant to purchase the 650i due to its age and common problems (which are ludicrously expensive). But your guidance has given me the confidence and knowledge to know the issues to look out for and how to fix. Cheers buddy. Time for me to search for a mechanic to tag along, before I purchase the car 🙂

[@TimmsBMWRepairsandInformation]

Glad I could help!

[@jonwarren6718]

Timm, I see that the under hood insulation on your car looks a bit wonky like mine did. I have a 2005 645CI Cabriolet w/ 75K. I looked into replacing the insulation and found it quite costly especially when there was nothing really wrong with the insulation that I had other than the "tabs" no longer fit within the slots in the hood. I trimmed the tabs and cleaned it all very well and then used a silicone adhesive to re-install it. I am no longer embarrassed to open the hood. It looks so much better. I was thinking that as nice as your car is that this would be a simple solution and your subscribers may enjoy this one afternoon low cost upgrade. Please keep it up, I cannot tell you how much I appreciate all of your videos. Many thanks from the U.S.! Jon Warren

[@kav7059]

Thank-you for this. I always wondered why my E46 330ci was reluctant to initially accelerate hard in Drive and seemed quite happy just cruising along. Then I realised that Sport mode and changing down wakes the car up, and it knows you mean business!

[@TimmsBMWRepairsandInformation]

Good man!

[@talm5154]

Really appreaciate these videos timm, grew up in my dads 645 when I was 2 or 3 and after selling the old gal and buying a newer 650 in 2010, it passed down to me when i went to uni last year and i hope to make it last forever (no worry she's not being abused)

[@jonwarren6718]

I own a 2005 645ci with right at 75k miles. I just a few days ago drove it “spiritedly” for about 100 miles on a nice country road and the car performed very well and as expected. Last night I decided to take my wife for gelato and less than a mile down the road pulling out of my neighborhood the car suddenly shut down and stopped with no warning. A big red light came on that I have never seen before. It would not restart for a couple of minutes but finally did. I was able to get the car home but just as I was pulling in the driveway I noticed reduced engine power came on. Once parked I turned it off and restarted it and everything went back to normal. I do keep the car on a batty tender so the voltage was good. What would possibly have caused this very worrisome episode? Thank you for all of the driveway hints and repairs. I recently was able to replace my cabin filters and flush the under hood drains with your help. Keep it up all of this is very much appreciated!

[@EpicGamerrrLolz]

do you have a code scanner? if not just go to the car parts shop or the mechanic and tell them to scan it and give you the codes that will tell you exactly what it is but without those codes it’s impossible to tell it’s just a guessing game

[@davematthews414]

Thanks Tim. Another great vid. I drive my 630i like this to get the best out of it, but mine has a different intermittent hesitation where the engine literally does not fire on any cylinders for a second or so if I press the accelerator anything like quickly. If I lift off before the revs have died off completely and reapply smoothly, no issues. If I don't lift off, the engine will die completely or backfire through the inlet manifold. It only happens once every blue moon (every 3 or 4 weeks) when driving, and using the the method in this video certainly reduces the occurrence. I can force it to happen when not driving by just pressing the accelerator quickly to the floor from idle (once the engine is warmed up). It won't happen if the engine is cold and still on fast idle. I don't know if you remember the accelerator pump on an old school carb? If this pump wasn't squirting fuel down the throat of the carb during fast throttle opening, you would get exactly the same symptom as I'm seeing. No faults ever showing in the ECU. I' plan to remove and check the DISA valves and the VANOS solenoids first as they are easy to do, but both of these should be throwing codes if not working...? Any ideas..?

[@chazshier]

N52 here also. Absolutely identical situation. Changed plugs, coils etc and no change. Did the pcv recently. No change. Mine doesn't actually misfire but it essentially freezes. Engine holds in a near idle like rev and it's almost as if time has stopped, desire foot being near flat on the throttle. Lift off and try again with a less aggressive press of the throttle and then it's fine. If you're pulling out onto a fast Road it's a potential hazard. Let me know if you resolve it!

[@TimmsBMWRepairsandInformation]

When it is safe to do so, switch off the DTC (5-second press) so that the ASC+T symbol is shown - let me know if this changes anything

[@stephenkeen1384]

Brilliant! I have a manual, so other techniques to make the car understand you mean business, but same concept. You need to communicate with the car to get the car to talk to you and give you the best that it has. This is the antithesis of the appliance/car mentality that is popular these days. 😊

[@TimmsBMWRepairsandInformation]

Very true!

[@priit7777]

Just brilliant! Gotta try this now also after I had changed spark plugs, stuck DISA valves, all the possible oils and liquids; and cleaned vanos solenoids and valves. 😀 (tbh all those things needed to be changed anyway long time ago also, but previous owner apparently didn't bother... so not sad about changing them. got rid of rough idle and horrible fuel consumption, but the hesitation was still there...)

Thanks - all well so far!

[@alexcohcoaching]

You can also use Inpa software to adjust minimum valve lift - the computers generally adjust this for you over time based on how you drive, but it's good to set it up for your own preference - it should be between 0.2 and 0.8 mm. The lower the minimal valve lift, the lower the consumption and the more responsive the engine is. With Inpa you can also adjust transmission adaptations then take the car out on a few different routes and run it through its paces. It will then adjust shift points, throttle response etc. It is a brilliant system when you understand it. As for the video in general, if you just press the sport button it will drop down two gears and allow for an easy overtake. You should also run the throttle body adaptation procedure every few months and the car will become much more responsive. To me personally it looks like your valve lift is set too high and the TBA should be done. I have the 650i coupe and for overtakes I never have to move the lever as it just kicks down two gears or so depending on how much I press the fun pedal. If you want your gearbox to be more responsive, an xhp tune is good and it will actually prolong it's life. It's quite cheap and easy to install. I have the stage 1 as this is after all primarily a GT car and it has to be smooth. Stage 2 and 3 are quite aggressive.

[@TimmsBMWRepairsandInformation]

My valve lift at idle is 3mm - that's probably small enough!

[@alexcohcoaching]

Yep 0.2 to 0.3 is fine :)

[@blademan7671]

1000% this. Been doing it for years.. As Timm says, it becomes a second nature movement, and it also lets passengers in your car know, that they should brace themselves. 😂 Throwing it into sport mode also puts the pedal into a more direct mode mode with the throttle, or some some would say more sensitive. Experience with an e53 4.8is and e39 M5 (manual). The e38 740 doesn’t have steptronic, so I can only drop it down a gear. I wasn’t aware of the why behind the torque converter lockup, I only knew it worked. 😅

[@TimmsBMWRepairsandInformation]

You can use the D432 boxes in manual mode, I used to do that in my E32. Start off in 2 and sports mode selected (1st gear), switch sports mode off (2nd) then you have 3 (3rd), 4 (4th) and back into D for 5th. It takes a bit of getting used to but is great fun

[@blademan7671]

I think the D432 and even the 6HP start off in 2nd gear by default, unless you put them into sport mode. With the D432, dropping it into 4 will cause it to select 1st from a stop.

[@JamesCarroll-jb2ns]

I had this same thing just shift into sport it fixes it

[@bmw328iowner8]

Good chat, useful every day, and 100% accurate for me. Some of this is new analysis to me and greatly improves performance on demand in my 328i. Some of this gives the words needed to explain that certain performance lag I have long observed and have been trying to overcome. How the doodad mechanically works with the flux capacitor is new to me. The power lag when flooring the gas pedal of my 328i has always been disappointing because flooring it does not instantly produce speed and and power wanted in exchange for max use of fuel. One second is too long to wait to get up and go. Sport Mode alone is enough performance for most situations but laying the shift on top of Sport Mode gives the instant muscle that is sometimes needed. Improving traffic flow for others is half the fun. This maneuver makes driving better for me and drivers near me who want to pass, change lanes, or are unsighted of the road and traffic ahead.

[@TimmsBMWRepairsandInformation]

Glad you like the video. Sport mode on the 650i is hateful, too jerky and the suspension hardens up along with the steering!

[@andrewwynn]

Great video. Two things you missed. One: kickdown; if you press the throttle request pedal to the obvious bottom the car will take seconds to decide to break the TC clutch and downshift but if you push extra hard to "105 %" that will instantly signal the engine you want instant power. It will immediately down shift to the lowest gear available (often this will break traction so current speed and surface conditions matter) Two: and this one's my favorite; say you just need to add 10-15 mph to get to a better position to merge etc, as you are aware pushing the throttle request pedal one inch will do very little at cruising speed. If instead you quickly bump the pedal first to 2" down immediately pulling back to 1" down you'll get the exact effect of "left and up" without having to touch the gear request knob. You'll get TC clutch disengaged and one or two gears shift depending how far you retreat from that 2" bump on the throttle request. You can keep on the pedal the car will stay in the lower gear but as you bring the pedal up it'll naturally shift back to cruising gear and lock the torque converter back up. Try it I'm betting you'd find you use it half as often as the left up method. Caveat; when I had e53 I used the left/up method much more but now with n55 and 8 gears it's more like 70/30 bump throttle vs. up: left. Great explanation on how to tell the car when you want some power on demand and love the video on Valvetronic that's how I found your channel. Subscribed!

[@AlexRussell-bb7mq]

Personally the best way to get rid of the hesitation or drop down as you accelerate hard is to fit an induction kit, the issue is due to air flow as the normal intake restricts it when flooring it too much There is only one I could find for the 650i I imported from America. Yes it £300 but the difference is amazing. It is proven from independent reviews to give an extra 12bhp. The mid range is now so much better. Pull away fast at 30 to 40 and the thing takes off. It's feels like DS or sport but with full gear range and no high revs on slowing to sharp corners like DS or sport which can keep the revs up too much. Best £300 I spent makes the car so much more enjoyable.

[@WMRV]

Earned a sub from me, I'm gonna try it the next time I go to accelerate cause for some reason lately its just been bogging down accelerating after I've already stopped needing the power as much and its kinda annoying (2007 328i touring, so not expecting too much power but rather just not bogging down)

[@onkelmicke9670]

Do you think it is actually the knock sensors?

[@TimmsBMWRepairsandInformation]

It all depends on which engine you have - if it is pre-facelift (M62) then probably the MAF. If it is post-facelift (M62TUB) then that opens up a few more possibilities including the MAF!

[@TimmsBMWRepairsandInformation]

No, knock sensors are slow to act - try E0 high octane fuel

[@onkelmicke9670]

M62 (pre-facelift) -97 540iAT. MAF units aren't cheap.

Great tip. Have you ever experienced funny drivetrain/gearbox behaviors around 30mph? Seems like it either keeps spinning at 3000RPM or upshifts way too aggressively, making the car super sluggish. Only an issue around 30mph.

hard to explain my problem, but under light acceleration i get this "hesitation" in the induction noise only, sounds like its cutting out but power delivery is still smooth. problem i also have sometimes is the car just jerks when id hit the throttle and i have to pull over then it just shuts off. im replacing the valvetronic actuater but not confident itll fix since i get that weird induction noise even with the actuater unplugged. my idle and coldstarts are better with it unplugged though. already replaced fuel pumps, sensors, coils and plugs. valvetronic codes do come up but only after stalling out and reflashing the car so itll start.

Enjoy your videos and was hoping the one about resetting the upper and lower limits on the window might be an easy solution to my problem, but no go 😢 I have a 2004 BMW 645ci convertible. The rear passenger quarter window drops when the top is opened, but does not come back to full up, only about 3/4, when the top raised to the closed position. If the top is in the closed position the window goes down but only comes up to about 3/4 position. In other words, no problem lowering the window at anytime, but it only comes up to the 3/4 position. In both cases, a very slight pull on the top of the window while raising it draws it past the 3/4 position and it finishes rises nicely on its own to full up. Any suggestions, or is it the dreaded regulator replacement issue? Thank you!

Does switching it to DS mode and back do any damage ? I feel like I shouldn't do it very often, although it feels needed when I need the power.

[@TimmsBMWRepairsandInformation]

No, you can pop it backwards and forwards as much as you like!

[@JamesCarroll-jb2ns]

If you maintain it you can drive it as hard as you want and not worry

[@KevinLovely-e4b]

What if you’re at 60mph downshift and it sputters before acceleration? What’s the issue ?

[@TimmsBMWRepairsandInformation]

Do you get spluttering any other time?

[@jimp1646]

Great video as always.

[@TimmsBMWRepairsandInformation]

Thanks again!

When I am coming to a stop the car jerks into first gear. I have a 2005 645ci

[@TimmsBMWRepairsandInformation]

Change the seals on the gearbox between the mechatronix and the body - called bridge seals, a common problem!

[@ZzxOPTICxzZ]

The nicest BMW driver on the roads 😄

[@TimmsBMWRepairsandInformation]

You should hear what I say off camera!

[@ericborich]

I have 2008 650i. When the engine is cold me car accelerates fast from a stop. But when the engine warms up and I floor the gas from a stop there is very little power of acceleration until it’s hit 2000 rpm’s. What could this be. I have no check engine lights or anything.

[@TimmsBMWRepairsandInformation]

MAF gives behaviour like that - only buy OEM BMW

I have had the eml light come on today, I have had no issues with engine over the past year after buying car it has ran just fine. Today it is not happy, it feels like it is not getting fuel? Engine is surging when gas pedal is down halfway in neutral it sputters a little rpms go up then down not moving my foot on gas pedal at all any suggestions please

[@TimmsBMWRepairsandInformation]

I take it that you have an 850ci?

[@JohnHynes_at_lookituplive]

@@TimmsBMWRepairsandInformation engine running rough idle it's the idle air control valve 👍 I didn't even have to replace it I took it off sprayed brake cleaner and WD-40 inside I watched the video of somebody else cleaning it until the mechanism inside moves freely put it back on and it works fine.

[@avneetkainth9816]

Excellent video!

[@TimmsBMWRepairsandInformation]

Thank you very much!

[@dukedub]

what causes the big hesitation at 1,600 rpm - 2000 rpm in second gear, is that also the torque converter? mostly happens when cold temps, once the car is heated up its not as noticeable

[@07wrxtr1]

My girlfriends 2010 535i just started doing that with the recent colder weather… no issues later once it’s warmed up…

[@TimmsBMWRepairsandInformation]

Have you done the transmission bridge seals?

[@thethomasj1795]

I know you aren't a fan of sport mode ( I am I have a 6spd manual) why not just press the sport button and mash the foot to the floor?

[@kyreesmith2464]

He made a video about 2 years ago explaining exactly this

[@TimmsBMWRepairsandInformation]

I hate Sports Mode - it just messes everything up and is not much fun when cruising! kzbin.info/www/bejne/eoCWhoquf5qHZ6c

Hi Timm I have an e63 645. Cold morning today had a rough idle / seemed to be misfiring and “increased emissions” on the screen. Any ideas?

[@TimmsBMWRepairsandInformation]

Replace the PCV's. they are often a source of unmetered air

[@arjunsamuel]

Hi there I have an E92 M3 manual. The same thing happens, juddery movement on low gear pull away. Will this fix work on it?

[@TimmsBMWRepairsandInformation]

No, that sounds like a clutch problem....

How do you do this on a m340 i 2020 ??

[@bluerineimb1148]

I've found the best way to solve this is a remap I have E39 e60e53 all did this all have been remapped and it was not happening after the remap on all cars

[@TimmsBMWRepairsandInformation]

Yes, that's one way to do it!

[@freddevore5327]

2009 650i can I use the paddle shifter to get the same power response?

[@roggyrs4739]

I do. Sport mode and downshift for power when you need it.

[@TimmsBMWRepairsandInformation]

Yes, that's the way to do it!

[@Charlie-pz1iv]

You are only downshifting. Annoying still. U have to remap your ECU. 😊

thank yo

My pleasure!

[@tracyfayeanglo3177]

Too EZ fixed your sparkplug gap

[@memphisreighns753]

You know what its Almost time to throw the whole thing in the trash Nonsense. Disa, vanos, throttle pedal sensor, i dont even care to investigate anymore waste of mo ey all around. Its great car that is quite but its got problems every few months. Windshield pump fails every 1 to 2 years. My advise dont buy a BMW am 6 k im maimtance in 3 years forget it Get honda works or lexus etc

[@TimmsBMWRepairsandInformation]

You are probably right, BMW's are high maintenance that's for sure

[@edLambert]

There’s no way that can be good on an old automatic transmission

[@TimmsBMWRepairsandInformation]

My 840ci has almost 200,000 miles on it and it hasn't complained yet!

[@RS265trophy]

remove the carpet from the pedal 🤣🤣

[@lpfinyt05a]

Or just buy a manual ;)

[@TimmsBMWRepairsandInformation]

That's true!

[@amelsfr]

because it's a crappy bmw, that's why

[@TimmsBMWRepairsandInformation]

Good point, well made!

[@JamesCarroll-jb2ns]

If it's not maintained like most bmw but when you maintain the abused N62 it will treat you right then you can add power it is power hungry I'd say you can throw a supercharger with everything stock and still jump from 325 to 450 475hp with nothing else

[@consumercellc1109]

My x5 with the n62 goes into this mode automatically when going up steep hills and it takes a while to let go when at the top. After a while of revving quite high it will finally settle down and go back into economy mode. Not sure if that's normal or not

[@TimmsBMWRepairsandInformation]

Yes, normal - I always use Steptronic on hills to stop this happening

[@jcoach3064]

NEED UR HELP 🙏🙏 MY 01 BMW E39 530I WAS RUNNING GREAT ,3 WEEKS AGO WAS OMW TO WORK AFTER GETTING GAS IN MY TANK GOT ON FREEWAY AND BOUT 20 MINUTES INTO DRIVING WHEN STEPPING ON ACCELERATOR CAR JUST SPUTTERS !!! SO TOOK TO SHOP I ALWAYS TAKE MY BMWS TOO AND THEY SAID NEED YO REBUILD MY VVT SO $2,000 LATER STILL NOT WORKING,WHAT DO YOU THINK IT IS , ALSO KEEP GETTING CAMSHAFT POSITION SENSOR EVEN THOUGH REPLITHEM

[@TimmsBMWRepairsandInformation]

No chance, the Vanos does not cause immediate problems - possibly they meant that the timing chain had jumped over failed chain guides - but otherwise, no, the Vanos does not cause those problems.

[@jcoach3064]

@@TimmsBMWRepairsandInformation so they did a vanos rebuild and sealed it up checked my camshaft timing and flushed a bunch of sludge out of my engine as I had burned through 4qts without realizing it aftermarket pvc system so going back to stock so byrn less oil , but now running great better than before

[@KreamyKone]

I have a f11 535i with paddle shifters, I'm guessing I can just drop a gear using those and the same thing will happen? or is it better to use the gear stick?

[@TimmsBMWRepairsandInformation]

The paddle shifter will do the job nicely!
