Could anyone advise me if it is possible to replace the lights on my A4 2.4 1998 model? If so can I do it as a DIY job? Cost? Were can can I buy it?

 

I'm not sure what you are asking. Would you like REAL xenon lights like in new Audi's (~$300), or are you talking about cheapo $20 xenon look-a-likes?

 

they sell kits to turn your normal headlights in real hid's there kind of expensive or you can go with the cheapo bulbs

 

if you have a 98 you might want to start by getting a set of one piece e-codes

 

If all you are asking is, if it is possible to do put Xenons in your car, the answer is yes. I am luck that I have a 1996 A4 and the owner before me had Xenons put in my car. I have the receipts and they were almost exactly $300.00. As to where to get them and how to put them in, I can't help you there, but it seems that $300.00 seems to be the going rate. They look great.

My problem with my Xenons are that one of them seems to have condensation in it. What do I do about that?

 

dpouley, if you have condensation, that means that the headlights are probably the cheap aftermarket replacements....you can heat up your housing in the oven (might as well do both while you're at it) and reseal them with some silicon...
