intermittent starting issue
 

my 99 2.5 has an intermittent issue. It sometimes starts fine, i turn the engine off and go to start again and theres nothing, its not like a flat battery ,the engine doesn't even try to turn, also ive noticed some other strange things, on one occasion i tried to open the doors and the central locking didn't work, i opened the car with the key, the engine started fine, then as i was driving along i could hear the central locking trying to lock and the interior light came on, then when i turned the engine off and tried to lock the car the central locking wouldnt work, left the car for an hour or so and it was fine. Anyone got any ideas? its making me nervous of taking the car anywhere because im not sure if it will start when i come back to it.

Bad starter (ignition) switch. Easy, cheap swap.

id agree but theres the thing with the central locking not opening also which wouldnt be anything to do with the ignition would it?

If I didn't think that was your issue, I wouldn't have said so. A bad ignition switch has manifested itself in all sort of electrical gremlins.

The UK alarm system is completely different than the US model, and I could of course be wrong, but I believe the two are connected.

But, the ignition switch is an inexpensive part ($12-$20 USD) and not difficult to replace, so that's where I'd start. The Ignition switch part number is 4A0.905.849.B available from either Porsche or Audi, and there's also an inexpensive generic made by Meyle (Mfr. for Porsche/Audi), same PN#.

ok,thanks for that, ill start with that

so what did it end up to be? I think I have the same problem in my 2000 boxster.
