I have had this engine light/"increased emission" for the last 7 months. The shop I work with has changed valves, seals and valve covers all over the friggin place totalling about 6g's. Because I have an after market warranty I didn't pay too much attention.
But then the car started stalling and shaking. This time they told me it was the vaccum lines. I let them go at it and again...stalling and emission light.
Then I decided enough was enough.... After reading through this forum I came to understand there was a diagnostic wire specifically targeted or geared towards BMW vehicles. I purchased the Bavarian Technic diagnostics wire and downloaded the software. I found the error messages as listed above which lead me to this thread. I have purchased the ccv pressure valve kit x2 I figure I'll do both sides while I'm at it. There was a slice or hole in the diaphragm. Let's hope this is it, but I'm confident this is or was the issue. Thanks again.
Shake at stop.
Stall after warmed up and idling or reverse (low rpms)
Increased emissions light
Large cloud of blue smoke on long idle 3-5 min
Spontaneous bouncing rpms at low idle
If at any time I reset/clear the fault all problems were resolved for about 100km
