Hello people my glow plug light occaisonally starts flashing on the dash whilst driving my 54 plate mk2 octavia 1.9 elegance. the funny thing is i have just about 2 weeks ago replaced all 4 glow plugs with genuine skoda ones. also my front side light is out the indicator is on the dash light up, i have heard if lights go out some times coil light starts flashing any ideas? cheers

Brake pedal switch.

Mike B - I was going to say that, I had this on my Mk1 octy after owning it for just under a year, it was fixed under warranty.

Even now I still cant work out why the glow plug light is connected to the brake sensor

The reason is the glow plug light is connected to and managed by the engine control unit(ECU), when you press the brake pedal it closes the switch and sends a signal to the ECU to say that you are braking and to turn off the fuel supply, so that the engine cannot push against the brakes. If the brake switch is faulty the ECU doesn't get a signal from it to either say it is open or closed and senses the fault, the way it alerts you to the fact that there is a problem with the switch is to make the glow plug light flash. This seems to be a standard approach from all vehicles in the VAG group, HTH.
