hi all, i have a 2008 w209 and my passenger side xenon turns on and off (flicker like crazy) when driving. i swapped out my after market bulbs with the stock bulbs and they still flicker. obviously, not the bulbs, could it be wiring, ballast, control module?? i went to the stealership and they told me they cannot will not plug the car to their computer on to recognize the change from halogens to xenons. is this required? who in SoCal does this besides the dealership?

i did a search on the forum and someone suggested the following website, but not sure if anyone on this forum has any experience with them.

Is the car fitted with OE BiX? If so the car will be set to BiX = present.

If so - It's likely ignitor failing.

Yes it is required to have the car coded to xenon=present in the star diagnostic system. My local factory dealer does this for $50 here in Ohio. Takes 5 minutes and is required to make the computer recognize the xenon's IF the car is on. The lights will work with the car off and not yet coded. This is required with factory xenon lights. Not sure with the aftermarket as I have not seen/installed any of those.

so i here is the update: over the weekend i took it to an indy shop in LA (charged me $95) to re-program the car and had it coded to xenon=present. stopped the flickering. no other errors were identified on the car except from all the lights that i swapped out earlier but no major problems. by the way, the dealer did not want to code the car due to them being liable if there ever was a failure, besides they were charging $170 to just diagnose the car.

one thing that i noticed is that my passenger side takes 5 seconds to turn on, whereas the driver side turns on instantly. any ideas?

Badly worn lamp or ignitor failing.

thank you for your help. i will have the shop take a look and i will update the thread.

$95 to recode? That's almost (if not higher) than dealer pricing! Yes, it takes some time to pull the car into the garage, hook it up to SDS, and do the work, but even my dealer doesn't charge that much for a recode. They only charge $100 for a TCU or ECU software update, which is much more involved than changing the HID settings.

I got quoted 50 at my dealer to do the xeon=present coding
95 is way too high imo

fusionnrg

the dealer here quoted $170 and refused the change the xenon=present coding. do any of you know any reputable shops in southern cal?

Rudeney

Yeah, many dealers will refuse to code for "mods". Maybe there is a forum member nearby who has a copy of SDS. Sorry you aren't closer to me - I'd do it for you for free (or at least a cold beverage)
