Hi All ,
I have a 2003 golf 1.8t aum stock standard 125 k fully serviced , besides a forge 008p diverter valve.My car has full boost and is smooth when the car is cold , but when the car gets up to temperature (90 degrees) the turbo cuts out and has virtually no boost .The car is also very jerky when getting on and off the throttle.Scanned for codes none come up.Replaced ,pre cat lambda sensor , n75 , air filter , new plugs(gapped correctly) ,new n112 , n249 , repaired sai pump with bolts ,pcv valve in tee piece , rocker cover gasket , combi valve and lastly MAF .aLL PARTS ARE GENUINE VAG PARTS.done throttle body alignment with V CHECKER PRO.tried adjusting the actuator tighter by one turn at a time , made things worse.Checked for boost leaks , none found.
Any help would be appreciated , car is driving me nuts
cheers Donno.
