Overboost, Rough Idle. CRK?

[The Sasquatch]

Hi Guys,

Car: e90 335i, N55 manual.

I’m experiencing overboost and a rough idle again. Been to 3 different garages now who don’t seem to understand what if anything is wrong as no codes are thrown. Interested in having wastegate actuator reset but no one seems to want to touch it as codes aren’t generated. Before I try it myself I wanted to see if any other possible causes can be read from the logs below?
I notice ‘CRK’ is 23. Is this normal? Also would be keen to see if Vanos, O2s, Wastegate appear normal? Any advice would be hugely appreciated!
I’m sure there is a hardware issue as stage 0 or stage 1 exhibit poor running.

Pull, stg 0

Rough idle, stg 1 (same happens with stg 0)

Can you post a link to datazap for the logs, or embed them here on SS? I haven't embedded here on SS yet, so unfortunately I can't provide instructions for that

Hi Wheela,
Thanks for the reply. I’ve added links to SS logs above. Happy to provide/create more logs if useful!
