I’ve had the amber light and flashing light for a few days. Hawkeye says U2002 - general switch failure. I replaced the main switch (hand brake lever) and all good till today.

Both lights are back and switch is non- functioing

No screeching, no groaning, just silence and both lights.

I’ve read the helpful guide by Disco Mikey on Disco3 site, but this doesn’t help me.

I have also read about worn wires inside wheel arches, I assume I need to remove said wheel arch liners? Previously owned 1999 Disco 2 TD5

How do know if the knocking at the front has been sorted?

You can hear the knocking at the rear better
