Hello everyone, Have a big issue. I have a 2004 xj8 vdp.. My problem is this, for no reason, the warning lights in the tac. come on, all the gauges drop except for the fuel. the information box reads ( gear box -air susp.-traction-abs-ext) faults. as a result those systems begin to work poorly. When tested, they all indicate ok. This could happen with the key on and eng off, or while eng is running. Oh It also locks down the car.

Spent some money so far, even jaguar couldn't help. any thoughts????
