I can explain in detail if required Cheers Iain
neill54 Posted February 18, 2009 Author Posted February 18, 2009 well ian been reading up on a few things and you do seem to know a few things about boost. me i like the cadbury kind! on a more serious note been having a wee problem for a while now sometimes the car only boosts to 7 psi but only sometimes not actually had it for a few weeks now but i know it will come back so i was thinking about cleaning the boost solenoid first then fitting a boost controller of some kind ive got a cel light on at the mo(only when totally off the throttle) which says its a pressure sensor fault been trying to track one down but no joy help! car is running today like a dream but i know these probs are here and need them sorting! neil
GazTurboUK Posted February 18, 2009 Posted February 18, 2009 ive been looking into these too, with the boost controller am i right in thinking this elimates the factory boost solenoid?

Neil, your boost problem is directly linked to your MAP sensor, if you have a dodgy sensor or it is dirty inside preventing it from sensing the, ecu goes into a safe boost mode (by safe mode I mean it stops the boost solenoid from operating and you run off wastegate pressure roughly 0.5BAR) and the check engine light comes on, you can simulate this fault by unplugging the MAP sensor, it is also possible that the pressure switching valve (the other sensor that is attached to the MAP sensor) has a blockage or one of its pipes is blocked? If attempting to clean this system out use only carb or clutch and brake cleaner as it vapourises after use. Good luck with sorting this mate. Cheers Iain
