After seemingly sorting out the lack of any lights at the back of the car now just the brake lights, all 3, are dead. Everything else is working.
The first date I can get it to Williams is May 27th.
I'll take the round rear cover off to see if there is anything obvious, like a loose connector block or earth, but if not then it is one of the car controllers, the one at the back.
I'm getting fed up with driving up to Williams and back... and not driving anywhere else.
A CX PlusFour suddenly seems interesting again.
But not at £82,000....
