Trying to figure out this issue I’m having with my 2011 335.

When coming to a stop sometimes engine will dip below 600ish rpm and sometimes will dip bad it will shake, then come back up and settle.

This issue is ONLY, when coming to a stop and does not happen any other time. Not while I’m idling reversing etc.

I have 0 codes relating to the issue and unfortunately don’t have anyway of doing a Log at the moment.

I am currently stage 2+.

Any ideas what this can be? Car is fine to drive otherwise. Would just preferably get this fixed before it becomes something else.

Tricky to diagnose without codes! Have you noticed any other issues at all?

Nope that’s what’s weird. It’s just that. I don’t have any codes showing for anything related or fuel pump, injectors or whatever else it could be.

Maybe start with a smoke test to see if any unmetered air leaks?

My car is still in the garage having some parts fitted to resolve a number of things including some air leaks on the turbo inlet and outlet that didn't throw any codes and were only found through a smoke test.

Might give it a shot, seems weird if that were the case though that it only happens when coming to a stop not during WOT or under load etc, I get good boost and everything.
