LCI Balast question, for HID Bi-Xenon Lamps
 

Water got in and fried a headlamp ballast (and adaptive control module, but whatever about that) - I ordered part number 5DV 009 000-00 on eBay, because that's what the original one is / was.

Under that number, there's another number 349112018031AH - does that mean anything? Is that an update (yet compatible) revision of the 5DV part number? Everything else seems to match up just fine.

Bonus round: For the adaptive headlamp control module: all I have to do is get a new one, and then code in the new VIN for it, and clear the errors - then I should be good to go, right?


Thanks in advance!
