I wonder if anyone can help.
A few days ago my Skoda Superb SE L Executive TDI 190 2018 started to lose most electrical power for 1 second or so, not long after driving.
Sometimes it was noticeable due to heavy steering with loss of power steering, on other occasions the infotainment screen shut down and lights flashed on the dashboard.
Mechanically, the car continued. It was just an electrical power issue.
This mostly happened when I slowed down and then accelerated into a corner.
After these incidents, often a warning light came on for ACC and could not be cleared until the engine was switched off.
If the GPS was engaged, the route was lost.
As a starting point, I removed the battery, checked it was holding a charge and that all terminals including earth were clean and tight. No issues there.
After a matter of trial and error, I believe that there must be a short on the infotainment system - as the problem only occurs when this is switched on.
Any suggestions of what might be going on? And what might be the best way to test the infotainment circuit to look for a short?
Many thanks in advance
