Help!!
My dashboard is lit up like a Christmas Tree, I’ve had a diagnostic done but garage was unable to fix and now unable to get the car booked in until middle of October!!

A long shot but it could be a voltage insufficiency, battery failing, alternator not charging or battery just somewhat depleted.

Follow these instructions carefully and if possible fully charge the battery while it is disconnected.

Did you have any work done on the car before the faults occurred, or had an aftermarket radio fitted?

[Nicchat]

No I’ve not had any work done.

Hello Guys

For all of those codes to arrive at once, I would be looking for a blown fuse, or maybe a corroded connection, maybe in the engine bay fuse box.

Try erasing the fault codes and see which ones come back immediately.

It did that and it still returns errors
