I've a bit of an ongoing saga with a failing dipped light. Changed bulb (1DS Xenon) nothing. mechanic told me ballast probably at fault. Then a joyrider reverses into me, unluckily taking out the wrong side. But mechanic swaps ballast from smashed unit to malfunctioning light unit, light still not working but we now have a warning light (which I'm told we didn't have before, but i think we did). He tells me it is due to corrosion (leaky fuel filter cap, and missing rubber cap) and that the unit ballast connections are likely corroded also.

So the part number on the light unit is  OEM 3T2 941 016 E or 1ZS 247 047-12. Which I can't find available anywhere. There are plenty of 3T2 941 016 some bi xenon and some not but I'm not sure the significance of the last letter and if there's any interchangeability?

 

Any tips?

That's pretty helpful, thanks @superbdreams

Is there an official lookup or list of parts with descriptions so that I can find out the differences are. Sounds like I'll just have to rule out most of the ones the that parts site recommend for my car as they seem to have a different body/engine type.

 

Another thing I'm considering is replacing the wiring in the headlamp but can't find much information about doing this. I repair amps as a hobby so am not shy of electric work. If it saves me £400 replacing a couple of corroded terminals then it worth a crack. But I guess these all in one units don't have separate wiring kits available?

I got the wiring harness with my ballast


And still have it if you want me to post it you?

Its sitting in my glovebox just incase

you need to split the headlight to get access a couple of tutorials on youtube

Not for the faint hearted but doable

Made my day. Yeah that would be great if you're happy to do that. I can reimburse you somehow, paypal or otherwise. Or if it's simpler just purchase new if you know a source.
