hi Damian i need your help on this
i am in Cyprus i have an AUDI A4 TDI 1.9, i took the car for basic servise to a not authorised AUDI engineer but he has that multi computer diagnostic tool,he changed the oil,air and fuel filter ,since then the turbo is not kicking in the car sounds like ford transit and lost its power,i took it back and he put the original fuel BOSCH filter and again the turbo is not coming in,is it possible that the inlet and outle tubes of the turbo are blocked with dirt and the turbo is not sucking fuel,or is a problem with the turbo. also if my car is fixxed how much is the uppgrade to 155hhp?
