Car jerking on acceleration

Jaz335i · 06-18-2022, 04:11 AM

Hi everyone
I have a e90 335i and experiencing issues with it
Car would jerk around 1500 rpms and whole car would shake like i am driving on a gravel road. It happens when on load like when going uphill at around 1500 rpms even with cruise control on. No modifications on the car apart from vrsf downpipes.
I am having a 30ff code that comes up and waste gate rattle which i am waiting on parts to fix the issue but i dont think these are related.
Just wondering if someone had similar issue and how was it fixed.

It's not missfiring is it? Have you changed plugs and coils?

No i dont think its plugs and coils
They are all brand new and also car would run fine apart from the jerks at under 2000 rpms

Just wondering could bad vanos solenoid cause this issue but i am not getting any codes for them

Do you reckon you have any idea what it could be

How new are the downpipes? Sure they're not hitting your subframe?

I had similar, it was only under low rpm acceleration. For me, replacing the vanos selenoids did it

Thanks for that,
I was also thinking maybe vanos could be playing up but i didnt had a fault code for vanos i even swapped them, cleaned them but no change. Maybe i will replace them.

Did you have any fault codes?
