cold start feels "not quite right"

mblaber · 07-28-2011, 07:34 AM

15K miles on 135i and cold start seems different. Slightly noisier and rougher and tends to stall easier when pulling from a stop. Once warmed up no noticeable issue. Any ideas? Had it serviced 6 weeks ago. The above issue started 1week ago.

I had similar issues started last week. Cold start the car would be very rough and blow smoke and smell like fuel.

Dealer replaced all six injectors under warranty.

Read up on leaking injectors
