Engine stalling after ppk tune

NKatsim · 03-27-2012, 03:40 PM

Need some help/advice...

I had the BMW PPK (tune only) installed last week and have driven less than 100 miles since. So yesterday, I was stuck in traffic and the car would stall at idle and would start right back up...happened about 6-7 times durring the hour of traffic I was stuck in. Never has it happend before. I would like to know if anyone has any idea what the problem may be before I take it in for service. Not sure if the car is still adopting to the new program???

N55 6speed manual, no service/warning lights came on and I always fill with 93oct. Durring the ppk install, oil and brake fuild change was done...car has 17k miles.

Thanks for any help....

First I heard this. Does it seem to have a rougher idle? What rpm is it idling at now? How does it run once the revs come up? How many miles on the plugs?
My cars a steptronic and it ran great right from the install. No hiccups at all.

You should take your car back to be looked at by the dealer that installed the PPK1. There could be a newer or better SW to cure this stalling problem. You paid good money for a PPK1 so thats what I would do.

Btw... did they replace your spark plugs? Many times the coil packs don't get reinstalled properly - the electrical connector on teh coil pack that is - doesn't fully lock into place. Just a guess though.

Thanks for all the help! They definetly did not replace any plugs which have about 17k miles on. Engine idle is steady and feels normal and drives fine. Drove it a bit today with no issues...thinking the stop and go traffic had something to do with it??? Looks like I'll be bringing it in to service...I'm cool with the shop foreman and will ask if he may look at it. Could it be the fuel pump??? When I picked it up after the install, I did notice a long crank...only time it happened and now it starts normal. Thanks again!

You should have the dealer scan for any codes. Could be anything really. But from the sound of it it could also be your HPFP on its way out.

IF your car had the latest bmw SW flash... before your PPK1... its possible that they need to setup some throttle adapations. I know when I had my car flashed here in Germany... BMW's latest SW has some anti tuner codes.... that cuases a wierd idle. My tuner knew about it and within 30 secs got around the new SW that BMW loads on the cars.

Sounds good...I'll post an update after I bring it in. Thanks!

There was a thread about this issue recently and it looks like the symptoms (revs dropping and sometimes stalling) is widespread and irrespective of tune (happened on stock, JB4, Cobb and now PPK1 tunes). Some folks have conjectured that it is a dirty TMAP sensor (the one on the charge pipe). I'd ask your dealer to look at that too.

Of course it could be HPFP, injectors, or spark plugs.

Update:

I finally had some time to take it back in for service. My tech raised the idle by 150 rpm's...looks like the issue has been resolved.

Thank you for all the help!

Hmm I dunno that seems like a shitty fix to me. Other n55s are having the same issues. Do you still get idle fluctuation but no stalling?

NYC6 · 04-11-2012, 05:20 PM

Interesting. Did the give you a reason to why the car was stalling while the car had the OEM idle? Seems this is the first N54/55 that needed the idle bumped up. I would be concerned they're masking an issue by just raising rpm.

was typing while Frankin posted. I wasnt aware that this is somewhat common with N55 PPK's.

Not a problem with PPKs just the n55 in general, there's a thread below about it 3 pages long. It's titled downpipe stalling or something.

But I agree seems like they are masking the problem by just raising the RPM.

thanks, I'll take a look at that thread.

NKatsim · 04-11-2012, 07:33 PM

Hey fellas,

It was actually my suggestion to raise the idle because I was concerned with them probing the entire car looking for a reason. Especially, after hearing it could be an electrical issue??? I never had this issue before the ppk...I did have the idle fluctuations but never stalled. My idle is set at 800 and steady...no noticeable idle fluctuations as before.

I'll keep you all posted if any changes...

NYC6 · 04-11-2012, 07:44 PM

I think you made a mistake by suggesting that. The car is under warranty, its a BMW installed tune, you had no issues(stalling) before PPK. Its their responsability to make it right, no matter what it takes or how much it costs. Putting a band aid on a potential problem might come back and bite you. I would make them solve the issue and give you a good reason why it happened in the first place.
