right headlight out. went to vw and they said xenon control module was bad. changed module light worked for 10 minutes module burnt out again. does anybody have any idea why? dont want to put another module in just to burn up again
I am currious, did VW test the system after the module was replaced? I have limited understanding of the HID light systems on the car. Leave it to the Germans to computerize a freaking light bulb. I do know that the conrol module has the job of detecting when the igniter has made sufficiant ark and temperature, then maintaining the proper voltage to keep the ark going. Maybe the problem is happening before the module come into play. It could be the igniter or the bulb. I do know that there has been a lawsuit filed against vw for knowing that they have instaled faulty HID systems since 2004. The suit also states that VW sent TSB's to there dealers and instructing them to tell the customer that this is a rare .
Yes, it's the ballast or yes it's related to the self-leveling. I need to have a look at the Bentley wiring diagram, which I need to do anyway, because I bought a pair of e-code headlights (not HID) that have power distance adjusters with it's switch integrated into the dash light dimming switch.
I'll do so when I get a chance, and post up my thoughts on what may be your problem.
