Bmw 128i stutter in idle

[Pelican Parts]

What scan tool did you use? Does the 'stutter' always happen or usually when you start the car for the first time only? I had a similar issue with my 135i and needed new plugs and coils.

I was using an Ancel 410 enhanced OBDii scanner. The stutter happens whether the engine is cold or up to temp. Did your 135i throw a check engine light? And how many miles were you at when you had the issue ? I was thinking it may be spark plugs but I was expecting to get more life than 46,000 miles from the original sparks.

It did throw a CEL and actually went into Limp Mode, but that was associated with a leaking valve cover as well - my car had around 80k when I had to change the plugs and coils.

If it's stuttering due to emmissions/engine issues the OBD2 codes will display.
If stutter is due to transmission issues, a generic OBD2 scan tool cannot communicate with the BMW trans module.
There can be no transmission codes displayed, due to lack of communication with the EGS.
