p0234 is engine over boost condition. According to Volvo P0234 is a turbo control valve. Maybe a wiring issue?
Did you do a hard reset after clearing the code? hope this helps!

Sometimes the fuse looks good,but replace it anyway,that sensor in under your dash,its red and round.

Did you test all the parts befor fitting ? Faulty parts would need to be replaced , have you wired the lights independently ? If so it shouldn't affect the CCM.

This is what my code scanner says:
P0234 Engine Overboost Condition
If you have a non-turbo model, then it's probably something else. It may be a bad turbo overboost switch. My S80 is non-turbo but I had an overboost switch go out on my Mercedes and it shut down the turbo but I had the same error message. Good luck!
