Involuntary Brake Lights

[Herman]

Brake lights are driven from the light module. There is no direct connection between brake pedal switch and lights themselves.
Brake switch feeds into the LSM and the LSM controls the lights.

• How is your battery
• Check for fault ground connections
• If you pull the brake switch plug off, does it still happen
• Do the other light function normally

My guess is either LSM or a bad connection

Had a similar issue appear on mine, but not quite the same.
If my wiper stalk was left in any other position then off, the wipers would start to operate at random intervals, even when the car was locked & alarmed.
I found a small amount of water on the RHS of the boot, and the Sat Nav DVD unit had signs of corrsion on the casing.
I removed the DVD player and the odd wiper problem went away.

Interesting one Steve. I have had issues with damp but my boot is currently dry since replacing the rear light seals. However damp does effect the driver's footwell and should be considered along with the other suggestions. Thanks very much to all.

Thanks Herman - 1. Battery appears to be A1 although I have to periodically trickle charge when flat.
2. OK - will do.
3. Have tampered with brake switch plug but no change to problem.
4. All other lights function correctly
