Fault: light assist

Featured Replies

Out of the blue, I’m getting a light assist fault. Fine one day, not the next. Fault clears if lights are switched from auto to manual but fault returns if main beam is reselected.

Any ideas?

Thanks. .

Several possibilities hard (impossible?) to know which without a fault code scan IMHO.

Thanks. Will get a scan carried out.

I've now purchased a CARLY reader. Here's the message:

Having cleared and read again, a slightly different message about communication with the ECU.

Any ideas please?

Mine failed recently - there is a PCB inside the mirror which can fail. I bought a mirror from a scrappy and it worked again with no issues, straightforward to replace.

There's a couple of threads here on the forum.

That looks like the one - mine at least!

Worth a try at that price? They're V expensive from Skoda.
