Just bought a cupra but it has a few issues I've scanned it with a hella diag tool and its showing 16955 implausible signal the brake lights work as they should and the signal is correct I've checked it using the diag tool and its send the correct signal as it should I changed the switch any way and readjusted it still no good the fault comes back its also showing 00668 which is a power supply issue and it won't clear I've checked all the fuses and they seem fine.......... Anyone else have any ideas where to look? It's also got a dead abs sensor would explain all the faults or would they be separate??? Any help would be appreciated it's driving me mad the lights constantly on.

Ive got a faulty ABS sensor on mine at the moment. I'll run Vagcom and let you know if I get the same codes (assuming you are in no immediate rush to get it sorted and can wait until after Christmas?)
