I recently purchased a used 2014 Wildtrak with the driver's side (Right hand side in South Africa) low beam not working.
I initially thought it was just the bulb, so I replaced it, and ended with the exact same results. The high beam works fine though. I tested the voltage.
With the low beams turned on, The right low beam voltage reads 7.4v, and the left side reads 12v.
With the high beams turned on, both sides read 7.4v on the low beam and 12v on the high beam.
From the research I've done, it seems the issue is the BCM that requires a reset after a possible short? As though the BCM reduces current to the circuit to prevent damage. I have no idea how true this is. I have plugged in a cheap OBD2 diagnostic tool, and it did not pick up any fault codes. Unfortunately it can only read and clear faults, and not do any programming or resetting of the modules.
Am I on the right track with this problem? Or could it be something else? I've already contacted my closest dealer, but the quote just to run a diagnostic is a joke.
Any advice would be appreciated
