Bought a new PTU, hopefully will arrive before the weekend for the track day. While I'm waiting for it, I'm wondering if anything else could cause my symptoms. Besides normal cutting out, when I stop the car and have the key in the "ON" position the dash lights don't come on light they normally do for a start-up. I have to wait for a minute or two and then the dash lights come one and I can start the car as normal. Ideas? Is this also a symptoms of the PTU cooling down?
