Check fuel filter first may be clogged or have water in it. Can be drained from the bottom thumbscrew on most TDi cars.

Hi , Im looking for a handbook/ users manual for Audi A4 2005 2.0 tdi avant. Anyone know where I can download one? Thanks


You can look for Haynes Repair Manual for your car, they are mostly sold on any auto repair shops or auto zones, or order it online. I'm not sure if you can find any pdf format of it though. Hope this helps

Hi my audi 1.9 tdi is losing power badley the acceliration totaly went its just had a new turbo so i dont think its the turbo. I,ve been out in the car a few times and the problem seems to come and go...


If somebody replaced the turbocharger with a new one, you must check up all command vacuum lines, the entire air intake system (air pressure pipes, intercooler, connections, EGR - throttle vane, ...), and also turbocharger and EGR command solenoid valves (three pieces). Could be also MAF sensor defective! Here you have the vacuum air pipes connection picture for Audi A4 1.9 TDI (AJM engine):
