My 2006 A3 2li tdi suddenly had the glow plug light flashing when the ignition is switched on and continues to flash with the engine running. At the same time the Brake lights are also on with the ignition switched and with the engine running.
I have read a few forum posts which suggested it could be a Fuse or the Brake Light Switch so I checked the brake light fuses (inside the car and under the bonnet) they look fine so fitted a new brake light switch. Problem still there. I also replaced the central brake light cluster (LED) in the boot lid. Problem is still there.
I plugged in a reader and there are no Stored Codes, I reset the codes anyway. Both the brake light and the glow plug light went out briefly and then came on again.
I am at a loss. Does anyone have any idea what the problem might be and how to fix it? I fear taking it to a VAG garage will only result in false information and a lot of unnecessary costs.
