I have been chasing the P0171 and P0174 codes on my 06 325i. I could not find a vacuum leak, but I looked under the valvetronic and saw oil, so I replaced the valvetronic gasket and my codes went away, my idle was smooth again and my MAF was reading 6 g/s when it had been reading about 3 g/s before replacing the gasket. Solved my problem too! Thank you so much!

The leak was the source of oil on the outside, the proper re installation of the valvetronic motor was the solution for both the oil leak, and rough idle.

great work mate!! yeah bizar such a little gasket can cause that problem!! i had a oil filler cap once with a super small crack in it, wich caused a simular rough idle problem and power loss even! turned out previous owner damaged the filler cap by screwing it on wrong...i first also went the coilover,plugs,solenoids route and went nuts not solving it!!! then read about oil cap somewhere and found out that way where the problem was...new cap and problem solved!! so there you go...sometimes its the small and not so obvious things on an engine that can cause trouble,but can be sorted superquick and easy!! :-)

Got to say, this video really helped me so I thought I should also come back and give my little contribution. Before changing the valvetronic gasket the car would run lean with the MAP sensor plugged in and sounded like the engine was about to grenade itself. With the MAP sensor unplugged the car would run nicely but a bit rich with LTFT of around -13% to -15%. Changed my valvetronic gasket (and valve cover gasket) plugged in the MAP and the car is running like a star. LTFT and STFT are close to zero now. Thanks a lot.

Quick tip - each time you remove the valvetronic motor you have to relearn its end to end position. There is a function for that in ISTA and it takes about 20 seconds or less once executed. If not you'll end up with less performance depending on how close you placed it into the previous position.

About the valvetronic motor how to reinstall it? To put it into servicemode and take it out i understand but what is the correct way to install it again? Do i really just need to screw that back on or do i need to put it into servicemode again? Also after it is installed i've read that you need to relearn it with ISTA or press down the accelerator for a couple of seconds when the ignitions is on. So anyone can take there time and explain this step by step? :)

Once warm, its down to 6-700 and a little unsteady idle (not as bad as yours was). My main concern is it going straight to 2000rpm- do you think a dodgy valvetronic filter could do this??

I wonder if it was the leak, or if maybe the valvetronic motor was just slightly misaligned... and then this would explain a rough idle a bit better because I can imagine just a milimetric misalignment on the valvetronic motor wil cause the valves to be slightly more open or more closed than they are supposed to be and the engine will be struggling.

Hi George, does/did your RPM hunt or flutter when you apply light throttle (usually to target 1200 to 2000 rpm) when parked or in neutral? When I try to increase revs to 1500 the engine will hit it then drop down again and I'd have to apply more throttle to compensate. Then as I put more load on the alternator/drive belt (i.e. AC, lights, heated seats and window etc) the rpm will decrease and hunt a little more.

Hopefully I can get an answer, after changing my valve cover gasket my 08 n52 idles erratically way worst than what you showed us with your car. I've changed everything spark plugs, Ignition coils, all gaskets, and the ESS gasket. The only time I ever had an idle problem was when my air intake coupler basically dried up, rotted and cracked. This issues shows the same symptoms of the last idle problem which is erratic idling along with the battery draining.

Yes it has to be relearned but depeding on how close you seat it back to its previous learned position you may end up with just a little loss of performance.

Hey G - its NOT the valvetronic motor gasket! Its the fact you have the some black coils and some newer type grey coils - IS a problem - when you change the coils the idle will improve massively - failing that its the vanos solenoids but you have done that? Im sure you improved things by changing the gasket and reseating the coils. If this doesn’t work I have one other suggestion. But I’m pretty sure thats a problem on your N52. The black coils are a very old type and fail sooner than the grey type. Giving you your rough idle (but not bad enough to generate misfire codes) - Regards

Hi George, I recently had a water pump failure. It was fixed and everything is up and running again. However, I suddenly experience something fishy with the idling. It’s not relay rough idling or jumping rpm. It’s when I come to a stand it is idling around 800 rpm and after 5 seconds it drops to 700 rpm. It doesn’t seem like a harm or anything but I didn’t have it before, so I am wondering if it’s normal. Any idea where this might come from?

@@jonaskuhlmann642 What I’ve noticed on the N52 (on my N52N, magnesium cover engine) is that it seems to have 3 idle speeds. Cold idle is 1000 rpm, warm idle is 650 rpm but whenever you clutch in - whether you’re stopped or moving - it idles stop 800 rpm. I believe it’s to aid starting from a stop and / or gear shifting.

I had this on my E90 318i and turned out to be a small oil leak on the brake vacuum pump seal and rocker cover gasket at the rear of the engine bay dripping onto hot exhaust. Not unexpected when mileage is around 100K. I had the exact same issue with a 2002 E46 318i.

excuse me, I have seen your previous video and when you unplugged the MAF sensor, the idle smoothed , if I was you I would have ruled out the sensor just as you said, but now the problem is solved from the valvetronic motor seal , why did the idle smooth after unplugging the sensor if it was not the issue , I dont understand it . Also another question , I'm a beginner but please explain this to me, the valvetronic motor seal is leaking out oil and letting air in , is the problem is the oil getting on the spark plugs not letting them fire properly or it is the air coming in? if it is the air how can this create a problem since the air is leaking in to the cranckcase and not the intake manifold?

I have done more research, it’s the PCV system it sucks blowby fuel vapors from the crankcase into the intake manifold and replaces it with clean air from the intake after the MAF sensor and before the throttle valve, which regulates the pressure of the crankcase, when a gasket is leaking unmetered air goes into the crankcase and gets sucked in by the Pcv system. I’ve seen cars with oil leaks that run good, I guess it depends on the severity of the leak or the Pcv system itself. BMWs have more complicated Pcv systems but the principle is the same, search for Pcv positive crankcase ventilation, and feel free to reply if you need anything

any un-metered air going into engine means incorrect fuel/air ratio
@stever5893
@stever5893 2 жыл бұрын
the reason is, that the MAF sensor reads how much air the engine receives and tells ECU so it could provide a good air/mix ratio. if the sensor is disconnected the reading will go to default and the engine will not fluctuate anymore. when you step on your pedal more air is being introduced to the engine which will require more fuel. that sensor provides the air intake data to ecu and it will provide correct amount of fuel.

The problem could likely have been the valvetronic motor seal all along. Disconnecting the MAF will actually disable the valvetronic motor, and allow the engine to fall back on the 'MAP' sensor method working the throttle body (therefore reducing rough idle in his case) You can also disable this motor by disconnecting the eccentric shaft sensor on the valve cover, which is probably a better way to go about it. As for how it caused rough idle I'm not sure. Perhaps oil leaked onto some grounding wires or maybe it did cause an air leak who knows. But disconnecting the MAF and getting smooth idle doesn't always mean the MAF is at fault (though it quite often is) Make sure to check that eccentric shaft sensor plug too for leaking oil. And if you decide to disable the VVT motor + MAF, make sure you clean the 'MAP' sensor (usually on the intake manifold) and check it's working correctly.

07 Z4 SI 188k miles. At low rpm at start up. I get a bouncy rough idle. But at high rpm. No issues at all. I’m thinking it’s my disa valves. Since they regulate air at low rpm as well.

Hey George any updates? My n52 has that nasty start that sounds rough and the shaky idle. I had the intake manifold replaced for free during recall work and the valve cover has been done recently as well... Going to follow your Video on cleaning the Vanos filters first but this feels a whole lot like a vacuum leak! Maybe run a smoke pot with the valve cover off? Cheers
