7 faults suddenly.

[lodge]

Hi,
I have a 70 plate Leon Cupra 290. It’s only done 20k and is standard except a revo map. I’ve just been out for a drive and 7 faults all came on at the same time. The first was the tyre pressure monitor, I checked the tyre which was fine so reset. Within 15mins of driving it came back on followed by ABS, Headlight balancing fault, Hill assist, Stop start and 2 others. 7 in total. Anybody have any ideas at the main cause or had a similar experience. car runs like a dream and never missed a beat. Remap has been on the car 4-5mths without issue so can’t be that.
thanks in advance

Do you have an OBD scanner to check codes?

No unfortunately

It could be a million things on a modern car, need to get the codes.

Sounds like the speed sensor has gone as the ABS System is connected to most systems when it goes the car lights up like an xmas tree.

Ah ok might be something in that. I was doing a couple of hard pulls at the time. Nothing silly of course just some pulls in 3rd

I have had to replace two of them sometimes they just go.

I had similar on my 2018 Leon on 35k miles. Caused by a failing battery. New battery & all faults disappeared.

I second this ^ my lad had all of these faults show up suddenly on his S3, new battery installed and no more problems
