325ci stalling

So given that I'm probably the best driver in the world, I'll start off by saying this issue isn't related to my ability to use a clutch.

Have noticed its exceptionally easy to stall the 325ci - especially when manouevring it at low speed, be it in 1st or reverse.

Its not throwing any codes, but I'm guessing its sensor related rather than mechanical. Has anyone had similar issues and managed to resolve them? Have seen a lot of posts online about it, but almost none seem to have gotten it sorted.

Cheers

Few options worth looking into
Maf (simple test unplug it)
Rubber boot intakes(remove both check for hairline cracks)
Cdv(take it out its garbage)
Vanos seals(if bad engine will bog down at low revs) they are a must on an m54 usually fail at 60k

My old 325 touring did this and it turned out to be a cam sensor or something like that!

I've spent the last few months nursing a 325 back to health, not there yet but almost. I replaced the vanos seals and some vacuum rubbers and these made slight improvements to performance but more noticeable improvements to cold start lumpiness. The biggest improvement was fixing the disa valve. My car had your exact symptoms and was transformed after I sorted it. The flap on the disa wears on the shaft and becomes stuck. I bought both the vanos and disa repair kits from i6 automotive. Only takes a few minutes to get the disa out, couple of torx screws, t30 I think, and you can test by closing the flap and putting you finger over the little exhaust hole on the unit. It should flip to half closed position and then fully closed when you remove your finger. If it's worn then electrically it would be functioning but mechanically it's doing nothing so no codes.

Cheers Seano. I don't seem to have any of the regular symptoms of that - it starts from colds perfectly, idles perfectly, not quite sure if its pulling through the gears perfectly - its quite sedate compared to the M3. Its only the low speed manoevring which is causing it to stall. Probably worth checking it out all the same.

RE: 325ci stalling

Yeah, maybe I shouldn't have mentioned cold starts in my last post. The disa wasn't the cause nor did it solve that particular issue for me. It did however solve the stalling at low speeds. Your initial comment about the clutch control is what made me think that you have exactly the same problem I had cause I bloody well knew it wasn't my clutch control that was causing it even though there were no codes. Anyway, well worth checking, quick and easy unlike those bloody vanos seals..

Bought the DISA kit and its on its way - sounds like the most obvious cause of the issue, so will see if it fixes it!

Ken, did you disconnect the MAF first to see if there was any change?

Just to hijack here. I'm not sure whether my MAF is working properly or not. I get a code every now and again and disconnecting it makes the engine drop for literally a nanosecond and then back to normal and no difference in performance while driving. My mechanic buddy reckons the live readings all check out and I've found a few cracked rubbers which I assume would make a difference to the reading. So, my question, what difference am I looking for when disconnecting it.

Nope. Want a look at it this weekend - didn't want to try the AFM and not get anywhere, and then have to wait another week. The DISA kit was very cheap and it won't do any harm to replace it anyway, so at least I can rule out two options!

As above! :)
