Rough Idle 2011 128i

Okay I have done a search and have found similar problems but not the same. Only when stopped in gear (auto) it will drop 150-200 rpm return to normal. It happens with AC on or off (one of the checks from other posts) and is not constant it does not do it all the time. Any ideas?

First thing I'd be looking for is a vacuum leak post-MAF. Check for loose clamps and cracks in tubing, especially around bends. A smoke test is the sure way to find it, but requires special equipment.

Have you pulled fault codes, and if so, what are they? I'd strongly encourage doing this, as it may make it much easier to locate the issue.

No check engine light. This is my first "Modern" BMW car so have not gotten a code reader yet. I can do a vac. test but not until Thursday. I am planning on getting new Plugs and Coils. Are there any Aftermarket Coils or stock the only choice? how about suggestions for Code Readers?

Could it possibly be the coils? I have a 2011 128i and apparently it came with faulty coil packs from the factory that lasted only 40k miles. I was having issues with my rpm's when it was happening.

It could be the coils, or it could be something else, or a combination of factors. The big plus to having a proper code reader is that you can avoid throwing parts at the car by accurately diagnosing the issue before you start. I use the Foxwell NT510 from ECS that comes pre-loaded with the BMW-specific software, but there are plenty of other options, depending on how deep you want to be able to go and how quickly you want it to work out of the box.

That said, being an old school sort of mechanic, the ignition would be a reasonable suspect, though I still think a vacuum leak is the more likely culprit. I would stick to OEM for the coils.

I have had this same issue, both before and after my AA headers, tune, exhaust, etc. I have had my local Dealer check it out with no pending codes.

In addition to the rough idle my engine has also died when cruising to a stop. Still confused at what it is. At the moment, my best guess is MAP sensor (need to clean) or the contact between the spark plug and the coil pack boot (saw this as a possible solution on the e92 forum.

Should note that I am manual, if that matters

I just ordered the foxwell/schwaben for ECS tuning, it's on sale 15% off until tomorrow or so. I think $169.

Mine did the same. Still haven't figured out what is wrong with it.

Died again rolling to a stop light, getting pretty annoying. Also dangerous when I'm headed into a turn and power steering cuts out

You should really take the time to build a cheap leak/smoke detector. It could save you a lot of time and money. I made one for $8 walking around a hardware store.

Good luck.

The car can store fault codes without triggering a CEL. You should definitely try pulling them - I can't imagine the engine would stall multiple times without the DME logging something.

Interesting, I was totally unaware of this recall. I searched my VIN on BMW's recall section and this is not listed. Searching through some older threads, circa 2014, my build date and engine seem to fail in line with the recall. Strange.

Anyone have any other information on this?


Thanks!
Mark

If it doesn't show as pending in the database it's likely already been done.

They're supposed to put a decal in the driver's door jamb too, right?

3 of the 4 exhaust vanos bolts had loosened on my car, it would stall sometimes and eventually threw the vanos unit jammed/stiff code.

First I've heard of this...I mean, makes sense, but I don't recall seeing a decal, and I've definitely had the VANOS recall done (and the two before that).

Interesting. I haven't had any recalls performed yet (by the dealer anyway). The label is mentioned in the recall campaign bulletin.

Kind of glad to hear this honestly; the stickers could add up fast since we're up to what, 5 or so recalls on the e82 now?
