I'm opening this post to get some help and also to collect information from various sources to help upcoming forumers.
My 2004 156 Ti has OEM Xenon headlights.
The previous owner put a metal plate underneath the car that "pushes" (let's rather say it even bends...
) the linkage that gives the info to the Xenon ECU on how to level, so the light is always "down" (but god it lights well !) ... But that is another issue.
For several months, my Left headlight was "blinking", I mean, sometimes it was seeming to "reinitialize" with this peculiar flash of light, sometimes it was working perfectly well, and sometimes it shutted down, requiring to switch my lights off then on to bring it back.
But since now two months, this healight definitely went down. Never able to bring it up anymore.
I'm planning to do the classic fault analysis from easier to more complex :
(btw the main issue for me is a proper bumper removal as nothing is reachable on the 2.4jtd 20V, not even a simple bulb swap
- Switching bulbs , and changing one of them (by good products..
) if this is the fault
- Switching Xenon Ballast (may has water or moisture), and finding a good ballast (or another make with a wiring change for the height adjustement)
-Ultimately accessing the igniters (which may involve "blind" cut of the headlight plastic), don't know if anything to clean here.
My question is : given the symptoms, would it be possible that it is caused by igniters ? Don't they just "ignite" and then are not in use later ?
Are they cleanable ? Would someone have a picture with a cut headlight with igniters ?
Thansk a lot and I keep you posted !
