Octavia_

Hi I've just gone an picked up a 2007 1.9 tdi octavia with very low mileage onky 125k km on the clock genuine too, there is a couple of strange faults though I've notice, when ignition on and car running the headlight adjusters are constantly operating going up and down, the dash cluster has been illuminating the immobilizer symbol dimly all the time and bright when any door is open including the boot and bonnet also when you indicate left the immobiliser and another green symbol with a foot pressing a pedal flashes with the indicator and when you indicate right the immobiliser flashes. The other issue is the right hand side rear brake and side light bulb is dimly lit wjen lights are on tried replacing the bulb but still no joy, im thinking maybe a bad earth connection ive tested the battery and checked the terminals all is OK, could anyone tell me where the earth is for the module or point me in the right direction
