C5 Diagbox Engine ECU 20.2v battery readingt!!!

[Assich]

I was running through the readings and in particular the accelerator pedal reading. When I press on the accelerator the % reading doesn't change at all. What caught my attention was on the engine parameters screen listed with engine at idle was rev's up over 8k rpm and a battery voltage of 20.2v? The auto gearbox ecu parameters were reading 749rpm at idle.

Those readings are clearly wrong but the first thing I would suspect would be your test equipment. What are you using and which car are you talking about?

C5 II. I actually think there is an issue as ABS ECU keeps losing communications and my auto box doesn't always appear to know where the accelerator pedal is positioned. I've already had a go at earth cleaning.

Diagbox is of the bay but reputable seller it would seem.

Not long had the car and sorting out all the issues not attended to by Po's.
