2002 VW Jetta TDI Headlights Cut Off

Asked by John Nov 30, 2021 at 06:56 AM about the 2002 Volkswagen Jetta GL TDI

Question type: Maintenance & Repair

My 2002 VW Jetta TDI Headlights cut off, sometimes going from High beam
to Low beam. The fog lights work. When the low beams cut off, I can switch
off the headlight switch, and the driving lights (same lamps) turn on, but when
I turn the headlight switch back on, the low beams cut off. If I pull the high
beams on, and release, then the low beams come on and stay on. The dash
lights continue to work, as are the tail lights.

We may need more details to properly troubleshoot this condition. Special electrical system tools are required for this job. So Check for: Defective/Malfunctioning Headlamps switch, defective BCM, defective one or both LOW/HIGH headlamps relays/circuit breakers. mentioned components not receiving proper current or not properly grounded. Thanks.

What 'Special Electrical System Tools' do you speak of? Where are the relays on a 2002 Jetta TDI?

Special Electrical System Tools: Digital Multi-meter to proper check for Current, Voltage and Resistance, Advanced ScanTool to check/reset PCM and BCM Relay/Fuse Box: There is one at Engine Compartment by the battery and the other inside under dash. Sorry to answer back late. Thanks.
