My idle kept jumping up and down every single Red light and sometimes even turned off!!! I did EXACTLY this (my filter was DIRTY DIRTY DIRTY) and now it’s running brand new again!!! .. Thank you 🙏 god bless.

[@WarpDriveM]

Glad that this worked out for you!

Did this solve the issue bud? Or did you have to fix something else?

[@tech42long35]

Awesome tip, thank you from every N52 person. Short, to the point, filmed-well enjoyed it. Never saw Anything about these filter-things. Very cool.

[@GPTSkills]

Thanks for covering this. My rough idle is not as severe as yours and does it momentarily on cold start ups. I already replaced my valve cover assembly, eccentric shaft sensor, ignition coils, spark plugs, vanos solenoids, cleaned MAF sensor, and changed oil to 5w30 instead of 5w40. I will be ordering new non return valves to replace them, regardless if they turn out to be clogged or not. Update: I replaced my non return valves today. I noticed both the motor and trans. were more smooth, so far. I only get the rough idle after leaving my car alone overnight, so I am gonna have to wait and check how the idle will be the next day after a cold start.

[@bonkeydollocks1879]

@@lukasp7406 I will have to reword what I said I think. I tried everything I could without knowing about these filters. To be fair a bmw main dealer and two independent "specialists" didn't mention these either. One independent adjusted the gap on the finger between the motor and valvetronic cams and it cleared up a lot but was never as silky smooth as when I first got it. It was running like a swish watch one minute, I overtook a lorry on a dual carriageway, then pulled back in and I noticed the hesitation and fluffy Ness on idle and part throttle. Baffling. It was absolutely mint with leather interior and the fancy stereo in it (forgot the name) I had to sell it quick due to having a company car, I sold it to a chav family from liecster who after about two months wrote it off. Such a shame

[@alexandert4252]

To really clean vanos solenoids you have to disassemble them (which is easy), otherwise there's no way you get to the dirt that is the piston in the rear side.

[@spazmochad]

Have you got a link to how to do it?

[@alexandert4252]

[@spazmochad]

@@alexandert4252 Fair, thanks for replying. I doubt many people take the time to open them up as the general consensus is that cleaning them doesn't help. I will keep it in mind that it's possible though when I look into my cold start idle fluctuations.

[@alexandert4252]

@@spazmochad Basically you just bend two metal pieces that hold electromagnetic part inside and whole thing comes out. It then becomes pretty obvious there's just too few parts for something to really break - electromagnet and a piston. But even with my clean motor i noticed some goo buildup that could prevent piston from moving all the way in the future which is most likely the cause of it all. And since i did "clean" it without disassembly first and it didn't go away proves why people think cleaning doesn't help - without disassembly it clearly doesnt. And don't forget to clean (or better replace they're cheap) 2 small vanos filters - those can cause a lot of troubles if clogged

I cleaned mine a while ago it woks fine. It just to jump so bad when i was in a red light

[@krookiemonster2673]

My 2007 x3 also chugs but has a really loud high pitcged squeal and does it all the time. Everything i found on it is that i need to replace the pcv vavle... which just so happens to supposedly be molded to the valve cover.. atleast from what ive been able to find out about it.. its creating a ton of suction and if i take oil fill cap off it stops squealing but will still chug just not as bad.. took it to bmw dealership and they said my valve cover is cracked.. didnt say where just that it would cost 2500 dollars.. there is no oil leaking tho. Which my dad a mechanic of u.s. domestic vehicle of 20+ yrs says there would be oil leaking out of a crack if there was one... there is some sensor on the top front of my engine that has had caulk rubbed all over the case and there was a bit of oil in the plug part of same sensor.. cant find what the sensor is to replace it tho.. for all i know that could be the thing i need to fix..

hi my z4 has exactly same engine like your n52 2007 i have a leak between transmission and engine , i thought RMS but it could be also oil pan or valve cover leaking from rear and go to oil pan i have also auto transmission like your 328i do you think it could be a transmission leaking at this place ? do you notice any leak from this place as you have exactly same mileage as mine thks

[@WarpDriveM]

To be sure you have to clean everything leave the engine running and if you have oil between the engine and transmission on the hole (where you see the flywheel) than it might be RMS. In my case it was just the oil pan gasket. I thought as well that is the RMS but after replacing the oil pan gasket i didn't haf any other leak. I have a video on the channel on how ive replaced that, and yes the oil is gonna spread till the automatic transmission even if is just the oil pan. Normally the trans doesn't leak.

[@z4funkdreamer986]

Warp Drive M ok my friend i will check it i did not hear something bad about RMS on n52 with auto transmission so it should be reliable i cross finger that it come from oil pan if it is RMS do you know if i need to do a gearbox oil change ? it will be a pain as i changed it 10000 miles ago

Rough idle can be caused by blocked engine crankcase breathers. The breather filters are built into the valve cover which will need to be renewed if this is the problem. When the engine is running remove the oil filler cap and remove it, if the cap is hard to remove or you hear any 'sucking' noise as you remove it then you have a breather problem.

If you replaced everything you just have to reset adaptations and will be ok

Dirty VANNOS is Common problem on N52 always use highest octane gas and helps with this issue.

[@Telstar_1]

Great video. Does anyone know the position of the non return valves on a 2008 N43 318i. I've already cleaned the Vanos solenoids, but didn't know about these valves. Thanks.

[@WarpDriveM]

On your engine you have no access to the valves, are in to the cylinder head.
