I have encountered similar symptoms on my 1996 audi A8. The car will start and the engine run under its own power, then cut out a few seconds after. After some hunting around I discovered that the problem is the wiring to the coil reader at the back of the ignition barrel. I understand this problem was present on some A6's and A4's.

Audi did relase a modification to the wiring loom part no: 8DQ972275 costing around £14 but fitting would require the removal of the steering wheel and columb surround.

Hope this helps!
Mike

Try replacing the engine temp sensor. Temp sensor is telling ECU the engine is hot when its is actually cold. After the 6th attempt there is enough fuel in the cylinders to create a ritch mixture, then it goes.

Fuel filter may be clogged, replace. Fuel pump may be failing, replace. Never let your vehicle "run out of gas" as all the residue collected in the bottom of the gas tank, will migrate through the system and create problems.

1996 Audi A4 1.8 petrol. Turn ignition key and engine starts , runs 2 secs and cuts out need to keep doing this until it finaly starts. Seems to be getting worse.


Car getting started then cuts off after 2 seconds.Its starter related issue.Either the starter is faulty or battery to starter connection is loose or got short in between.It has to be checked and replaced.Get the voltage checked from battery to starter.The battery should show 12 volts if fully charged.

Rear trunk door on '03 Audi A4 Avant does not properly secure.


the struts would have no effect on the catch at all. chances are the floor catch has moved inwards a little, re adjust to fit correctly/watertight.

2002 start-up problem


Hi there again

Sorry to hear you are still having problems.If you are going to change the pump I would certainly not recommend you do it yourself.If it is the V4 motor I am thinking of, you would need to get to it by removing the rear seat ,remove access panel , and pretty much play around in the gas for an hour or so to get it off in the first place.

What I did find was this on the net on a recall by Audi to replace 2002/03 model fuel pumps as noted below.

RE: 2002 Audi A4 Fuel Pump Change:


I just had my fuel pump changed out by the dealer. Here is what the letter said-

"Safety Recall JL 2003 year Audi A4 quattro with 1.8L Turbo or 3.0L engine and 2003 Model year Audi A6 with 3.0L engine"
The fuel pump on some affected vehicles may contain a carbon brush set that is susceptible to premature wear.

On invoice it says-

JL12 Install fuel delivery unit and sealing washer.
1 8E0-919-133-G Washer
1 8E0-906-087-P Fuel Pump

No charge for unit or install. Just call them up and give the vin number to see if your car is affected. On the other note of your code error '1&3 misfire',try and have it re-set (it might be an old error)and see if it comes back. Hope this helps ,and I will research your problem further with pleasure if need more help.

2002 audi a4 1.8 t cold start problem


It might be an injector problem.Sometimes if the injectors are not sealing properly they can leak fuel into the manifold even when the engine is off as there is still residual pressure there and you engine would be essentially' flooded' when you try start it again .After half an hour or so,and it would take some seconds after that to run normally untill the excess fuel is burned.

Have them checked and replaced if needed.

Please leave positive feedback if I have helped

Thanks

Audi a4 problem


I had a similar problem on my Audi A4 1.8T after three seperate trips to different garages I was told I needed a new ignition and it could only be re-coded at an Audi dealer - was told it would cost in the region of £500. As the car was not worth much more than this I did a little research myself and found that the ignition key may have been intermittenly losing its code (as sometimes the car would start ok) I had a new key cut at my local key specialist at a cost of £20 and its been fine ever since (that was over 2 years ago)
Hope this helps

Car starts ok then cuts out


HI,HANNAH,I SUSPECT YOU HAVE AN IMMOBILIZER PROBLEM.IF THERE IS A ORANGE LIGHT FLASHING ON THE CLUSTER WITH AKEY IN IT THEN IT IS THE IMMOBILIZER.THE PROBLEM WOULD MORE LIKELY BE THE DATA FROM THE KEY IS NOT GETTING TO THE IMMOBILIZER CONTROL UNIT,USUALLY A BAD CONNECTION AT THE READER COIL ON THE IGNITION.YOU MUST CLOSE THE TERMINALS SLIGHTLY AND INSULATE THE WIRING SEPERATELY.ANDY

Engine starts rough intermittently


First thing that I would do is Replace the Fuel Filter and get the Fuel Pump Checked out. It sounds like it is one or Both of these.
