Thanks for the video Nathan. Just ordered the Mostplus from your link. Didn't know I had a PCV issue until i performed a vacuum test on the cover after removing from e90 n52 (while changing gaskets). Thought I'd give it a try.

[@HollywoodHornet]

Nathan, I work with a woman who is selling her 2003 e46 330xi coupe with the M54. It's like a mystic blue color. The clutch went out and she doesn't want to pay to have a new one installed. It has 220-230 thousand miles. The engine is actually in pretty decent shape. I replaced the brakes, fuel filter, plugs, and coils recently. The tires are pretty bald, and the alignment is off. Also, the sunroof doesn't open or close, it's stuck closed, doesn't leak, but is missing the partition. She said she'd take about anything anyone offered her. Just giving you a heads up if you feel like doing a clutch job on an all-wheel drive e46.

[@chadriddle3517]

Hey Nathan , question our 2007 530i has a metal valve cover . I’m assuming it’s been replaced right ? It would of came with a plastic one from factory.

[@KB248FOREVER]

Hope those Vanos fix it for you, that is what I would have told you I thought was the problem. Had similar issues on mine.

[@interestingthings4404]

Great video, like them all since there is good amount of focus on essentials with going to so much detail to scare people even thinking about working in their BMWs. Would you mind posting video regarding change transmission fluid ? Would be greatly appreciated if that be for E60 2008 528i auto. Thanks again.

[@craig84downunder]

I’m thinking something to do with correlation between cam and crank angle is causing that issue, but vanos could be the problem giving the change after the solenoid swap

[@Joeshomegarage]

I just bought my 06 330i with 218k miles. Previous owner had valve cover gasket replaced. I've been fighting a MAF code and after finding a CCV hose broken and temporarily replaced it with a rubber hose I had laying around it's running good so far. I noticed 5 bolts missing from the valve cover, a few broken bolts including one of the 2 eccentric valve bolts. I guess he didn't take it to BMW or figured 10 out of 15 bolts is good enough!

[@joegrohmangolffoundation8981]

Nathan I need some guidance please. I have an e90 330xi. Last year I replaced the battery (the car sat with no battery for three days) when I put the new battery in I had 4x4,abs, red brake and dsc light all come on. Tried turning steering wheel all the way left all the way right nothing. Drive around nothing. Fault code is “ 005f39 clutch position unknown “. This was not on before the battery change. I have a foxwell nt530 for bmw. The scanner sees I have the error and will activate modules but when try to clear the code it can’t communicate with it properly. Also have junction box error 30 f-g. This all happens after the battery replacement. What were the adaptations you reset that you speak about in this video concerning the 4x4? Any help is greatly appreciated.

[@richardjohnson9702]

Merry Christmas Amber!!!!!!

[@Joeshomegarage]

Did you reset the ecentric valve or whatever that thing is called?

[@dannychen7694]

Could it be electrical issue? Maybe the wiring from the batterty to the computer that's causing the misfire.

[@allanconsuegra3815]

does a hose connect to the valve? it seems like a small hose connected there, but im bot sure.mines doesn't have it

[@tommybell]

So your saying that it was the PCV and the vanos solenoids but also actually everything else you did (coils, plugs etc...) however doing all the replacements was just PART of the solution because it did not resolve UNTIL you reset ALL the adaptions and you must have ista to truly reset everything? How, would I go about obtaining ista?

[@mty3606]

Coils now. Did you ever have a whistle noise?

[@lp2565]

Your assistant does nice work!

[@NathansBMWWorkshop]

Yes to bad he is leaving in.a few days

[@hayksamvelyan]

Nathan you found a serious corrosion issue with the DME connection. Why would you overlook that when you’re dealing with engine management issues?

[@vaporrecoverytech9805]

Did you try resting your valvetronic motor. After replacing your valve gasket it needs to be reset after being reinstalled.

[@Mrmagicss1]

IM HAVING THE SAME ISSUE DID YOU FIX IT????

[@spencerhulme1203]

HI Nathan, know this video is old but the content is still relevant! I have a BMW E92 320D M Sport, and i had issues that when i did hard acceleration i lacked power and the engine MIL light would come on. I had codes relating to the EGR being stuck closed, not enough vacuum, the engine was not cooling properly, when i took it on the road any constant acceleration or hard the engine management light would come on, like taking it on the highway, what it turned out to be! I changed all the vacuum lines and 2 Solenoids one for the EGR and the other for the Turbo a pressure converter the car know driver like brand new!

[@thisguyshorty3554]

What were your codes and symptoms?

[@Joeshomegarage]

I just fixed the broken wires for trunk lights but no reverse lights. Now I need to reset the Footwell module and after watching 8 different videos with download this and download that and none of the links work I'm still not ready to take it to the dealer for a reset. These should be easy things to find on the internet for a 15 year old car.

[@TheKeenMechanic]

Good video. Thanks

[@michaelporter3555]

Did you ever check the fuel pressure? With the age and likely mileage on that car the fuel pump could definitely be weak and could have been at least part of the problem even though it appears to be fixed now.

[@aimized1460]

Would a failing fuel pump cause the car feeling like it’s super weak? And my gas mileage is terrible I drive like 15 km but lose 40k worth of fuel I’m super lost

[@michaelporter3555]

@@aimized1460 I've seen BMWs have lean codes on multiple cylinders caused by a weak fuel pump. Especially if everything else that can cause the codes like vacumn leaks have been eliminated. Low on power, engine that's difficult to start, engine cutting out and or hesitation or outright bogging on acceleration could be a fuel pump. White smoke out of the exhaust can be an indication of running lean and possibly the fuel pump. All of that could also be a bad fuel filter. The high fuel consumption isn't typical but possible but if it's that bad you should have lean codes. If the vehicle is a BMW and is over 10 or 15 years old, has high mileage and has the original fuel pump you probably should change it since it's probably weak, on it's way to complete failure and at least part of the problem.

[@aimized1460]

@@michaelporter3555 yes the car is 14 years old , has 259k km , no codes or faults are present. However upon looking thru all the documentation I see that the fuel pump was never ever changed so it still has the original pump, i will most likely change it out thank you for your informative comment brother, seriously

[@jamesluke7377]

You've tried the possible DISA change/fix if my memory serves me. Possible vacuum issue and/or CCV system issue perhaps? I'm lucky I've had you and now also Dean that has helped me.

[@NathansBMWWorkshop]

it runs good now but went and ordered the solenoids just to be sure no future problems come up

[@86Damacy]

@@NathansBMWWorkshop I have the same clattering sound and misfire, it was the PCV?

[@pfmurphy525]

It was funny on the test drive & after the misfire you went to pull over but mentioned “after i run over the dead raccoon there 🦝 “.

[@stardavid6]

I have a 2006 325xi that at first gave me like 6 different faults. I replaced a lot of parts already including radiator and hoses. All injectors and injector plugs. I alo swapped out both Vanos. All faults are gone and car runs way better than what it used too but still feel a little rough while driving. I only get one 2A82 Einlass VANOS fault but on cold start or whenever I restart the car. I ve bought new oil filter cover cap and put that on as well. Oil is 5w30. Really dont want to sell car but I have run into a wall with this. Any advise would be greatly appreciated. Thank you in advance.

[@aimized1460]

Have you tried to swapping the solenoids around ? It could fix the issue

[@JohnnyCage4Real]

Nice video. When you had oil in the intake, were you experiencing smoking from the exhaust? Like more than whats normal? When you push the throttle for example? I have this issue

[@aarontylergood5325]

Figure out what it was?

[@JohnnyCage4Real]

@@aarontylergood5325 yeah it was the CCV system that was clogged, pretty common issue on the e60

[@chrischan5151]

I believe it's a fueling issue and the fuel module is failing. try replacing your ekpm2/ekpm3 with a brand new module :)

[@dbosnow2203]

Hey, so what fixed it?

[@rhiantaylor3446]

Hey Nathan, what you are looking for is a BMW of exceptional value where the price is held back by the risk of large workshop bills that you would not expect to have to pay. Perhaps a 7 series - take a look at Hoovies Garage and his $4500 760i video.

[@vishwaschaudhary6534]

Thanks for Awesome video. Quick question Can you reprogram an existing KeFob from one BMW to a different model of BMW car?

[@NathansBMWWorkshop]

I dont think so

[@conmanxtreme]

I had corrosion like that on my DME connector and it had leaked water into the DME itself and friend transistors on it so I ended up having mine cloned to a used DME and all was well again.

[@hayksamvelyan]

This right here is a major issue that Nathan overlooked. DME computer corrosion is a real concern with engine management issues.

[@aimized1460]

Damn I’m going to check mine now

[@Saicopateful]

Reading codes is not proper diagnostics. There's live data in INPA. I would recommending getting acquanted with it.

[@NathansBMWWorkshop]

Why use inpa whine have ISTA

[@Saicopateful]

INPA is simply much faster and has predefined screens with gauges. I have both.

[@peto22]

Yes. INPA (and other software from bmw standard tools package) are way more efficient and powerful than ISTA on Exx cars. Difference of engineering tools and dealer/service tools.

[@BMWDoctor]

@@peto22 I highly doubt that..... these tools are amateur tools if you saw at Nathan actually uses OFF the videos I doubt ANY of you have this software as im his provider inpa , ista all these tools are amateur tools when you use the real stuff then talk your all talking like your pros and Nathan is a newbie to this he has me who is more skilled then all you who sit at the computer WATCHING acting as if your so good YET I dont see any of you posting any videos showing your SO CALLED SKILLS !!!! as a matter of fact come on to my channel and see WHAT I DO brother you wouldnt have the brains or mental skills yet you wanna come up here talking about bmw standard tools like its something great your a newbie for the fact your even promoting it like its something great

I cant believe Nathan is allowing these stupid comments from people who have nothing to even come on here with your watching Nathan my friend remember that he aint watching you !!!! so clearly shows who needs who more just remember your subscribed he aint subscribed to you instead of all the talk come out and show us what your amateur tools can do your talking to someone who's been doing this for nearly 10 years and im very very pro at what I do I can gain access to ALL bmws without a key with the software I use I make relay boxes to hijack these cars with ease and yet your coming up here like your a pro with inpa please brother take your crap somewhere else where you can feel like a man like shoplifes channel
