Hi,
I have replaced the offside headlight unit, tray and wiring loom on my 2003 Cayenne S because the tray was broken, there were poor connections and the lens was fogged and not passing the MOT. £300 got me a new Xenon, tray and loom from an ebayer, which I thought was a cracking deal.
However (and I think this is unrelated to the replacement), the nearside xenon intermittently goes off, with dash warnings of Check Dipped Beam and Headlight Adjustment. I have checked the connections at the back and have sprayed contact cleaner into the plug and socket and it all seems a very snug fit.
The interesting part is the light only goes faulty under heavy acceleration.
I have also posted about poor starting / coolant leak / low battery power (?). Is it feasible that under heavy acceleration, the system voltage falls below 12v for the headlight to fail? (sounds mad, but true)
Or... is it something else, like a failing ballast pack?
Thanks in advance for any advice.
Pete
