Third Brake Light Warning

Post by FRANKFIXIT » Wed Jul 25, 2018 10:26 pm

Third brake light warning appeared today and then disappeared. Checked third brake light and it was working properly when the brake pedal was pressed!
Any ideas please?

Had the same last year, warning came up when driving, checked out when I got home all ok. Car was serviced shortly after it happened, OPC said no error codes present and all checked ok. Spurious no idea, hasn't happened again.

try a pressure wash, pay particular attention around the wheels and discs, very often little bits get stuck around the pads etc.

I have just experienced the same problem.An intermittent 3 rd brake light warning.
I removed the unit from the rear spoiler by depressing the spring loaded clip from the side with a small electricians screwdriver.
I found that the terminal socket hadn’t been pushed in properly by Porsche assembly. Make sure that the needle contacts haven’t been bent or damaged
Kind Regards
