So, I've gotten this code a couple of times and it shows up when my car won't start on hot days. It's not Audi-specific and I don't really understand how a hot day can have such an impact on the electrical system. The engine will spin with the starter but there is no ignition. I had a mechanic tell me it might be my aftermarket head unit, a relay, or a faulty ecu.
Does anyone know what the hell is wrong??
Any advice would be better than where I am now.
Thank!
