    Hi all, my bone stock 325i 5MT has been making a very annoying intake noise since I got it. It sounds a bit like the sound symposer noise (aka amplified induction noise) on an old Ford Focus ST, quite low frequency around 290 Hz (measured) at 2000rpm. Just imagine accelerating your car as you...

    I didn't expect the DISA valve to be pretty, but it also smells like gas. Is this normal?

    So I replaced my CCV system and in that process I had to remove the disa valve to get to where I needed to go. And when I look at the disa valve the flap inside had broken completely off so I decided to change that out too. I fixed my ccv and put the new disa in and thought it’d be back to...

    I have been trying to diagnose and remedy this problem for several months, and now I need the to call on the collective knowledge of the group. It all began when SES illuminated one morning as I was on my way to dealer for routine maintenance. The car was behaving normally on the roughly one...

    So CEL is on, throwing p0430 and p0456. The p0430 is most likely a exhaust leak I have with a bad manifold gasket on cyl 4-6 (New ones are just waiting to be put on this fun-filled weekend, got the penetrating oil ready), but the p0456 is a real ass. Replaced the gas cap because it was the...

    Hello everyone! I am trying to convert my 316i engine to a 318i, and I have stumbled into a little problem. Where should the disa connector plug be located? I simply can't find it.

    I couldn't find too much information about this procedure when I did it. I took some pictures, and came up with a couple of ideas along the way. Parts needed: A new diaphragm from https://vanos-bmw.com/disa-bmw-repair-kits (I ordered it on Ebay though). A DISA Valve in otherwise good shape (or...

    Hi guys, first post here. I just rebuilt disa using a repair kit. It did not come with the o-ring, do I put it on without it. I noticed the car makes a hissing sound coming from the area. Seems to run fine, no dash lights. Is there any way of knowing it it's a vacuum leak?

    Please, don't RTV as DISA valve, it won't work and you could do more harm this way. This image is a couple minutes after I began to clean it with a razor blade, but I'm pretty sure this was my vacuum leak along with my intake boots. Also a tip for anyone else who is struggling with cleaning...

    Hi everyone, my 325ci is making a terribly loud hissing noise from behind the dipstick. Previously, the dealer had told me that the DISA needed to be replaced for $650. Yesterday I used the German Auto Solutions DISA repair kit and the car is still hissing. I installed everything properly and...

    Hi guys, Just asking for some guidance in regards to what might be causing this noise. Yesterday I came across an unusual noise from the engine bay which I later found out to be my DISA. It was making a very loud whine but it stops when I pull out the DISA electrical connector. I've...

    Friends, In my first DIY venture under the hood for this car I have chosen the DISA valve replacement. According to my indy shop's evaluation, I need a new one. I have been reading up on the forum and feel pretty confident. Has anyone done this on an 02 330 ci vert? Anything special I...

    Hey I was cleaning my disa valve and idle control valve, put everything back together and now the car won't start. It will turn over, but fail instantly. It's throwing a P0102 code for Mass Air Flow Circuit low input. This is a daily driver me and need it back running. Where could I have gone...

    I have a 2001 330XI automatic with about 160K miles on it. It is my wife's daily driver. About every 2 months we will have a cold start issues. It either idles really rough with the roughness disappearing after 30-60 seconds warming up OR it won't idle at all and I just crank and crank with...

    The purpose of this post is to explain my diagnosis of the misfire problem my car developed. So my 2003 330xi threw a misfire code, and began to idle funny. I drove it home, and began to try to diagnose the problem. My code reader pulled a p1347 code. Misfire with fuel cutoff. I cleared the...
