LED are better than the standard DRL you know it too? you just need convinceing and a wallet the size of Richard Branson lol lets not settle for second best GARY_Z..... I dont know why Audi did nt put them on all A4 still trying to figure that out
Ur right about the voltage issue i ve heard that from a few people was hopig someone had got around to solving that problem bugger... getting the bulbs out could be a tad tricky to.

As for the cost well... all depends on LED ur guess is as good as mine maybe Bratty could enlighten us on that issue HEX-CAN cable for the VAG.COM thats around £200

heres an example on ebay

If you where to source all parts needed for th D.I.Y at reasonable price well this is whats in store for you next... personally i dont fancy doing this seems like a headache however paying someone else to do it wells thats an aditional cost right..... catch 22
