Someone have any good ideas regarding replacement of headlights. Plug and Play available? 2002 TT is what we are driving. I know there are probably hundreds of conversations on this but Imhoping someone doesn't mind my being lazy. Thanks in Advance

I also have a 2002 TT and would like to upgrade the low beams. What did you end up doing? Thanks - [email protected].

No one replied. I see the headlights on ebay but they cost a few dollars so until I get some feedback, I'll keep looking.

I spent some time looking into this. What are you trying to upgrade... the bulbs or the whole headlight units? Do you currently have the Xenons or the Halogens? If it's just the low beams - just upgrade the bulbs or get new ones. If the whole unit, you can't 'plug & play' between Halogens & Xenons... although that should be possible if you are willing to go into the wiring diagrams and trace all the wiring and components down for each type. Be nice if someone knowledgeable could write a FAQ on how to downgrade Xenons to Halogens units.

Right. Well I have whatever came with the car. I have replaced the current low beams and they work great. But the whole plastic face of the light is worn out.

Ahhh... You should have said that in the first place. Search for "Restore Headlights Audi TT" on YouTube and you get a bunch of videos on how to polish the lenses - using either a kit or just various grades of sandpaper and liquid laquer. This one is particularly interesting:

Just to say it... Go to a wrecker yard and buy a $5 old/junk headlight to practise on first though - you don't want your TT headlight to be the first try.

After your done, apply a PPF film to the headlight to protect it after polishing. (PPF = Paint Protection Film - preferably the thicker kind to minimize impact damage)

BTW - if you don't know what you have for headlight type - how do you know what bulbs to replace? Most/All 225s came with Xenons, but there's plenty of 180s with Xenons as well. If your headlights have ballasts, you probably have Xenons. If you replaced the low beams, then you probably have Halogens, as the Xenons have D2S bulbs which are pricey.

Don't race to the bottom and buy the cheapest D2S lamps on Amazon. They will barely last two years with poor output after year one. Buy genuine Osram from a legit retailer. You get what you pay for. Plus if you determine it is a phony knock-off, you have recourse from a legitimate retailer.

Osram's website has information how to determine if a lamp is genuine or a counterfeit.
