BMW 318iS E30 ICV Cleaning

If your car is having a rough or abnormal idle this is probably one of the first things you'd want to do with your car.
Tools needed:
Socket Set
Screwdriver
Carb Cleaner
*new hoses and hose clamps suggested

You just helped me fix my rough idle, thank you!!!

[@pavelgram4062]

Good stuff! Solved my rough idle and the car runs so much smoother now too!

[@gregoriogonzalez2346]

Did this today, the car idles smooth. Much better than before. Thanks for the video.

Great video! Just got my e30 318is last week. I have tons of mechanical experience but videos like this really help. My last car was a 1966 C10 so none of these hoses... ha ha

Im going to try this tomorrow, i cleaned the butterfly and throttle body area thinking it was the problem, this looks promising. Thanks

[@StevenHuyghe]

good video! not too hard but nice and clear explained :) my iS has sometimes an abnormal idle, I hope it will be fixed with a cleaned icv!

[@jimmover]

Nice this was exactly what I was looking for.

[@christianm.279]

Perfect, worked great

[@playordie7557]

Can i use brake cleaner ?

[@TrustEdGarage]

Yeah, it should be fine. Make sure it is dry before installing.

[@akilleez84]

Tried this today and my icv does not rattle.

[@TrustEdGarage]

It is supposed to rattle loosely inside. I would spray it liberally with the carb cleaner until you hear if moving easy when you shake it.

I just cleaned mine now its idling at 2000rpms help please!!!!

[@aniluzun2321]

Did you fixed ?

[@Bairdogg]

I accidentally pulled out that bottom hose trying to put the icv back and j can't find where it connects, help?

[@TrustEdGarage]

+Bairdogg I did the same thing, it attaches to a hose that runs parallel to the engine block. You can google BMW m42 IACV diagram, to get a better idea. Good luck.

+Ed's Mods just got it! thank you, I had to dig my hand around under the manifold for a while to find it but I did. thanks!
