The active light error resets it's self when the car is restarted but comes back on when you reach 40 MPH-ish, which fits with some other post I've read. My care also illuminates the corresponding fog light when cornering, this is still working fine.

I've got the Icarsoft MBII so I'm able to clear the codes and carry out some diagnostics.

Lets see what Saturday brings, I'll post up the result.

Thanks again.

Thanks

All the issues then gone. Never came back. Coming from Brunei, our imports are from euro markets I guess. Mine also had active headlights.
