FAULTY N75 ?

Post by ADYS4FKU » Thu May 22, 2008 6:30 pm

Hi guys. Have a bit of an intermittent lack of power/ boost problem around 3000rpm. fault code 17965 p1557 (over boosting) found in memory. Replaced both noisy DV s today an its still the same. Would a faulty N75 cause this problem as well? Thanks in advance.

I've had problems with my boost recently... Sometimes the gauge shows I'm getting the full bar other times it refuses to go over 0.4 bar and there's a noticeable lack of power. Yet when it cools a little the boost comes back!
Is this an N75 problem or somethin more sinister?
