My mate has an a4 estate which basically just died the other day.

It will start for about a second and then die.

Has anyone any suggestions he reckons its electrical but I reckon its fuel related as it starts but then dies.

Going to plug it in tomorrow but would be good to have some clue where yo look first

Cheers

 

Could be many things. What a4 is it? Petrol or diesel? Get it on a scanner and go from there.

is the immobiliser light flashing with ignition on?if the car doesn't recognise the key it wont unlock ecu so will start and die instantly

 

First problem, its an Audi

Second problem, it definately sounds like fuelling issues. Maybe a fuel rail sensor? Fuel filter blockage? Or more than likely a fuel pump.

Similar problem with my e46 330d, and turned out to be all 3 problems. Hasnt missed a beat since

 

No Audi/VW dont got wrong. German reliability lol.

 

Mine's been great, 100k of almost trouble free motoring and still more squeak and rattle free than my Mrs 18 month old 207.

I would hazard a guess the immobiliser ring on the steering column is causing the problem. Which platform is it.

 

Go on audisport.net plenty lads on there have vag com
That will check it for free.

 

Been talking to a few people and they say its the key at fault.

Audis are usually bulletproof!

It has done 180k

 

Most cars are bullet proof if they have been looked after.

 

if it is a key problem and light is flashing away then leave ignition on for 15 mins,light will stop flashing and go out then youll be able to start it and get it to a garage

 

Most VW/Audi things if problem with immobiliser it will start and stop after a few secs.

Needs fault codes reading , no good guessing..

Usually shows up 17978/P1570/005488 if 'engine start blocked by immobiliser'.

If key and or reader coil faulty possibly this code

I would like to bet someone has changed the keyfob battery and the immob chip has dropped out without being noticed (key type dependant) - seen loads like this.

 

If it starts and dies pretty much straight away then I'd hazard a guess at it being immobiliser related too.

 

my petrol audi did this was airflow metre

 

Its the key needs a new one

 

Or dear.

 

That's a 2.0tdi, my a3 is bulletproof and that's a 2.0
