Probebly a sticky injector, try putting a bottle of injector clean through the system, if not it could be burning oil.

2005 a4 while driving lose acceleration and power


Would really need more details on the vehicle. Petrol / diesel etc

Is the engine management light on? Are there any fault codes?

Power lose while driving is most likely to be caused by the mass air flow meter, leak at a vacuum or intake hose, turbo leak etc.

More details please........

Car works fine untill left overnight then wont start in the morning have to prime the diesel with the inline suction device under the bonnet then starts and runs fine


Air is getting into the fuel system allowing the diesel to drain back to the tank. Check fuel filter is tight, look along fuel line for leaks at any of the joints etc.

My Audi A4 2000 TDI year 2005 has run on two tanks of Bio fuel recently and it hasn't recovered... started stuttering. Fuel system has been flushed out, air flow mand air flow meter has been changed but...


Audi 1.9 TDI and 2.0 TDI engines with pump-nozzle injection system, (year 2005 included), don't have permission to run with Bio fuel !!!
First you must replace fuel filter, interflow a quality Diesel additive (for 60 liters Diesel fuel dosage) fill up tank with Diesel fuel and run at least 300 km on highway at 3000-3500 rpm in 4-th gear.
I recommend you Foerch Diesel Reiniger System additive! I use this additive from 3 years ago and is certified on Audi TDI engines!

No I am a mechanic at Audi. The problem is that the the air flow to the central tappets may be causing the air flow sensor to trip and that is why. Try putting a small amount of WD40 into the petrol and that will work, its a very common problem.

Mass airflow meter


Hi

It is fitted to the air filter outlet hose (the one which goes from the air filter to the turbo) and it is quite literally right next to the air filter. It has a wiring plug to it.
