Recently set p0234. Turned car off boost is strong and fine. Has only happened twice.
Possible causes: wastgate, vac leak, cracked turbo, dirty t map.

Any clues. I've re tightened all hoses and did the soap test on vac lines. Nothing there.

 

Did you change to a Forge release valve ?

 

Nope. Still stock bpv.

I'm leaning towards the turbo solenoid. Or low voltage.
I haven't climbed under car yet, so could be lower tmap wires hitting.

 

Mine needed the new valve at 30k dealer put new one in. I changed it to the forge, run good ever since. But you are right the lower t map had to be replaced at the same time due to rubbing, thats when they installed the bracket.
