    Hey guys, I have an '03 325it and I'm hearing a chirping type sound when I step on the gas. Sounds like the chirp is coming from around the intake/intake manifold but I can't locate it. Only chirps when I first hit the accelerator but constant acceleration will not cause any sound. The first...

    Hey everyone, so as the title states, up until just yesterday, car was running fine, no issues. Yesterday I ended up getting an EML light which would also go into limp mode. This seems to have been fixed by removing the idle control valve and cleaning it out, code was P1500. After this, the EML...

    Hello all, long time lurker and first(ish) time poster! I drive a 2005 330xi. So this past Sunday I spent about 2 hours replacing the lower intake boot (massive crack in it) as I was getting some nasty lean conditions. While I was in there I took out the ICV and cleaned it really good with...

    So, I've been trying to diagnose a rough idle, and a few other codes being thrown since picking up the car in May. Long story short, I wanted to check the ICV to see if it was stuck / dirty, to see if that was causing the problem. I got the ICV out, and it moved around like it should (give it a...

    When i depress the clutch quickly it causes the revs to go up, and this is most noticeable within the lower gears (1 and 2). This isnt a throttle related problem as i could be coasting in 1st and quickly push the clutch in and the engine will rev without me having ever touched the throttle. Any...

    Hi all. 2001 325Ci, very likely to be the Euro version, not US. I'm trying to do a throttle body and ICV clean, but the car is so old that everything is stuck. The ICV will not come out. I've removed the two Torx bolts and disconnected the electrical clip. Am I forgetting something? In every...

    Early this summer, I fitted a K&N cone filter directly onto my MAF tube as a replacement for the airbox altogether. It sounded awesome and ran great for a while, but then I installed an electric exhaust cutout and things fell apart. In addition to a blow ignition coil (which I swear must have...

    After chasing many issues, all new coolant system, new coils and plugs. Checked vac. Leaks and clean the ICV. There was no doubt the MAF need replaced. After replacing the MAF my 2003 325i ran like a new car, until it goes into limp/safe mode, which was a new issue. It has been throwing a p1500...

  19. DIY: Do It Yourself
    Hi all, I'm changing separator & crank case ventilation tubes. DIYs give advice to clean DISA and ICV as they are removed. Have you opened DISA and/or ICV to clean them? They both seem solid packages that won't open easily. I've already cleaned them externally. They both probably have O-ring...

    UPDATE!! 2/23/14 Hello Again! So I cleaned my IACV, I took it out, after a long war with the lower boot's jubilee clip being faced down (the person who designed it like that should die in a fire). My idle was perfect!...for 12ish hours, my check engine light when off and everything was...
