I've noticed a flat spot under full throttle at around 2.5k revs in any gear. Car is 2000 MK4 Estate. A noticable drop in boost occurs but car still pulls
At first I thought it may have been clogged filters, crap fuel or air-mass metre. I've cleaned the AMM but the problem still occurs. Could it be the wastegate actuator?
However, average MPG is just over 51mpg
