E92 335ia coupe idling problem

[cjohntoh]

Hi,
Can anyone help me on this problem?
My ride is a E92 335ia DCT coupe . Everytime when I come to a stop, my rmp will rise to 1000 than back to 750.
Car feels sluggish when moving off from stand still. When to workshop, check on the sensor, nothings wrong. Clean the throttle body, but still the same. Can anyone help me? Thanks...

Any fault codes?

Sounds like your intake manifold requires some housekeeping.

Hi, my 325 E92 recently also have the same issue. My mechanic told me most probably is carbon build up that lead to idling hunting and told me to whack my car to clear the Carbon which I did by driving to KL. Surprisingly he is right and hunting problem solved that you can try in NS highway.

Re: E92 335ia coupe idling problem

Ecu is a general term for a bunch of controllers that your car have. Each controller manages a specific set of functions a lights, audio, engine, gearbox, roof, antenna, instrument cluster.

The Dme manages your engine.

Other marques might call the gearbox controller - TCU.

BMW calls it the EGS.

N55 and N54 engine - No MAF sensors.
