P3053 - Starter Control Returned Message 50 Short to Ground Prior investigation and research I found ECU on Audi A5 has a burned circuit preventing starter from spinning.
Thanks, It helped, the starter started working, but now the glow light started flashing air mass sensor fault P102 (signal too low). Now what could it be?
Possibly caused by bad starter solenoid. ECU is linked to a starter relay from my understanding. ECU on the video was of an Audi A5. You could always check 12v supply to a starter on key start position to rule ECU issue away.
