Hello guys,
So I have started noticing that whenever I come to a stop after driving for 30 mins or so, the car shakes which I can very well feel it. No rpm jump. It stays still around 600-650 rpm.
Its 2011 335i 6spd. MHD stage 1+ with new plugs and coils. No code or unusual behavior while driving.
Any clue ?

I would start by monitoring for misfires under the threshold to throw a code.
You noted it does this after 30 minute drives.
Will it also do this at each light in the city after the car is warmed up?
Just trying to hone in on the most likely culprit. Timing recover, gummed up VANOS, poor injector, etc.
Do you happen to have a JB4 installed? If so, log this and upload. It may shed some light (fuel pressure, etc).

Any scanner with live data can monitor misfires.
Are you gonna eat that?
Problem is I don't think the DME is sensing it. So it won't report it to a scanner. I've got INPA, ista and typical ELM type scanners. I've reset adaptations and watched the rough running data. I can watch the rpm do a little dance but the DME doesn't seem to register anything as wrong. But I could be missing something obvious. So I asked.
