hey guys hope you can shed some light to what this may be.
got a 52 plate audi a4 1.9tdi. drives great only thing is sometimes it fails to start, well starts but then stops.

i'll explain, it will always start in the morning no problems, but after driving it, say engine stopped for 5 minutes then try to restart, it powers up but then stops. bit like how an immobilisor kicks in.
i dont think its anything to do with temp as when i drive it to work in the morning (1 hour drive) in the evening it will do the same thing. gotta try about 2 or 3 or even 4 times to get it to start.
to get it to start i gotta take key out, put key back in, sometimes even play with the stereo a bit, turn it on then off then it will start.

think its something electrical but dont know what.

PS: the plastic bit of the key fob is a bit broken but cant see if there is any damage on the inside.

it could be the transponder chip inside the key is loose m8, and it could be just rattling out of range of the coil around the ignition that picks it up, causing the car to stop

just a guess m8

you'll get a new fob on ebay m8, you can program it yourself but you'll need an obd2 cable and a copy of vag-com.
