I had an Audi A4, 10 years older than yours mind you, but it would start then stop, sometimes 10 times but would eventually go. I ran a little WD40 in the key barrel and put the key in and out a couple of dozen times. Wiping it with a cloth each time, lots of dirt came off. My theory and it's only mine, is that the wear on the key left dirty metal deposits inside which stopped the chip in the key being recognised. I believe they had a security chip inside the key.
Anyway after 6 months of this nuisance it never happened again after that. Fixed my problem and a lot of frustration. Maybe help you too.

Remove the fuel pump from the tank and check the electrical block connector and the wires underneath the unit that runs to the pump

Sounds like your ignition coils are going on you... but fortunately Audi has a voluntary recall for these on your car model, and will replace them for you free of charge. Contact your local Audi dealer, and they should take care of this for you!

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!

My 2002 audi a4 1.8t...somewhere in the vicinity of the passengers rear tire,i hear an air leak.its not the tire.i try to listen where its coming from exactly but can figure it out.its near the fuel filter...


I think you are hearing your fuel-pump. Try a few different things, with someone close to where you can hear the sound. Talk with that person. Ask if they can hear the sound with the car off, with the car in the run position(not running), and with the car running. Take notes, If the car has rear air-ride it could be an air leak. But it could also be the fuel-pump or an exhaust leak.
