RPM surge on start up

drmdvl · 09-24-2011, 12:00 AM

Hello,

Does anyone get an RPM surge with WARM startups. I get the normal higher RPM with cold starts, but with warm starts, the car starts fine then immediately acts like it is going to stutter and die. It revs from 600 to
1500ish about 3-4 times then settles down.
BMW says nothing is wrong!

Does this with or without Procede.

thanks for your help.
