Sputtering after startup? - BMW 3-Series (E90 E92) Forum

Doc K · 05-05-2013, 01:22 AM

I've been having an irregular sputtering lately for about a month or two, right after startup. Any suggested diagnosis?

Mods? Any recent service work done? have u checked for any codes??

I had the same problem. It ended up being bad injectors and dirty intake valves needed carbon blast.

How old are the spark plugs?

I had a sputtering problem with my 2007 RWD 335i (no mods) after a cold start. I took it in, and the first time the BMW dealership told me to get a carbon scrape done. Then, the replaced the fuel pump, but the problem still didn't go away.

I just got my car back, and they replaced the Turbo's because they said the wastegates were flapping. It seems to be OK right now, but I'm still watching it to see if the problem creeps back.

I'd be interested to know what other people's experiences are.

Ive had this since last appt back in Jan...

They did a software update for this and for vibration issue while engine is running and I D mode at stop light...

I would still suggest changing spark plugs. It's cheap compared to other things, and could solve the problem. I tried walnut blasting and stuff first and spent tons of money before I dd the cheap simple thing (plugs.)

My ride only has 28k miles, mostly highway, would I still need plugs?

MrD

Plugs certainly shouldn't be an issue at only 28k miles.

Thanks, I didn't think it would be an easy fix like that
