Title: Occasional boost
Post by: Expose on March 08, 2024, 10:07:38 pm

Hello, I have a bwa mk5 on 110k. It seems to have developed a fault where it will only boost to about 3psi through the whole rev range and feels really flat then about 20 minutes later after a few restarts it starts to give full boost. Seems to be happening more frequently. Replaced DV, PCP and cam follower in the past month. Haven't had the time to log yet. Any ideas on where to even start looking?
