Wiring on Porsche 996 C4S Rear Lights

[X7LDA]

Hoping someone can help.

Without going into too much detail; I had a spoiler painted on my 911 C4S and when it was fitted, with a new brake light, the garage in question made an absolute hash of the wiring. Absolutely mind blowing how bad it was. I didnt know until I ran it through an MOT and the garage doing the MOT pointed out the brake light was blinking in tune with the hazard lights. They charged me £160+VAT to fix the issue and the original garage have agreed to pay.

All good then, however.....the latest garage who fixed the wiring is taking the car back in next week as now the reverse sensors are going off when the brake peddle is pressed. T

hey had the car for a few days to fix the first issue therefore I am wondering if anyone has any idea on what they have done wrong so that I can help them identify it quickly and get therefore get the car back quickly? Happy to post pics if it helps.

There is a problem with the earths to the rear lights and reverse sensors and there is nothing complicated about the circuits, the fix is an easy one for a good Auto Electrician
