A4 cold start problem
I can turn the ignition key and it takes a few seconds before anything happens, no clicks or other sounds from the engine. The engine/starter starts to turn very slowly like its under a very heavy load and eventually it starts.
This will get worse and worse such that when I turn the key nothing will happen for a good few seconds, then the engine will try and turn, but fail and all the electrics in the car get reset as though the battery has been taken off line.
All the time everything else electrical will run fine, and once the car has been started, it will start instantly every time until another cold day.
This only happens on cold mornings and the battery is fine, and if the car doesn't start first thing, it will start fine a few hours later.
Any help as to what's going wrong would be greatly appreciated as its really frustrating to have the car fail just when you need it most.
Thanks
