A couple of times I've had issues with starting the S4. Turn the key and you get nothing apart from the ignition lights. You can keep turning the key for a few mins and nothing will happen but leave it for another 5 mins and it'll start up fine.
Anyone had that happen before? Just wondering what I should be looking for? I'd initially thought the battery was flat but it still manages to start the car so I'm guessing it could be more of an engine management issue?
It'll be in at Audi in a couple weeks for its service anyway but was just wondering if anyone had a clue what it could be in the mean time?
