1x S3 and 3x Fiestas.
Thought I would clean my throttle body today / never done it before. Wipped off the battery and removed the Tb. Very dirty both side, a good clean with carb/ intake cleaner, all dried out and refitted. Battery back on and reset the throttle in VCDS. Started ok and then drove like almost no boost! Went out for 1/2 hour and no change, checked for faults and all were good. Left it for a bit, took it out again and still it's very poor, in a quick logging session on block 115, it asked for 2,500 mbar at some points and it never went above 1,580! Can't see anything damaged and can hear the turbo spooling. Had a boost leak test just last week at r-tech and all was good.
