π΅ BMW 3 Series β one headlight completely dead
The car came in with the whole front light unit out: dipped beam, high beam, indicator and DRL all showing as failed on Check Control. Six faults in the memory.
Full ISTA diagnostic first. The lamp itself was fine β the fault was the LED driver module inside the headlight. No guessing, no "try a new headlight and see" (a new unit would have cost the customer several times more).
β
Quality replacement LED driver module fitted
β
Coded to the car with BMW software, so it works exactly as factory
β
Fault memory cleared β Check Control: No faults
This is the difference between diagnosing and parts-swapping. If your BMW or MINI has a lighting fault, we'll tell you exactly what's wrong before you spend a penny on parts.
