Re: Random engine light 1.9tdi
Only way to determine what it is, is by scanning the car otherwise you might be trying to solve all sorts of none existent issues and throw money at it when you can find the fault easily.
It must be a fault that solves itself when you drive. But the fault will be stored on the ECU.

Best is obviously to scan for the error that will be stored, but my money will be in the brake light switch behind the brake pedal. Check if your brake lights come on when you press the pedal, if not that's the problem.

Brake light switch usually flashes the coil (glow plug) Icon...TimeShifter wrote: ↑Sat Jul 24, 2021 8:20 am Best is obviously to scan for the error that will be stored, but my money will be in the brake light switch behind the brake pedal.

Engine management light will come on for stuff like Mass air flow, coolant temp sensor, EGR etc.
