Hi Whealey - congrats on your car - it looks really nice with those wheels.I am pretty confident on the computer but don't know a whole lot about the electronics in cars. Despite this, I am very tempted to buy a VAG-COM kit to do some mods to my A5 such as the DRL mods.
Can someone who has used one please reply and let me know how easy it is to learn how to use it and also if the codes/tuts on the net are enough to be able to work it out.
As for the VAG com mods, I'm just down the road from you in Doncaster if you want your DRLs etc sorting out. Beer chits are not necessary but probably accepted if offered. Let me know if you're interested.
If you do want to buy your own cable, then the software is easy to use and there are various threads on A5_OC that detail the necessary settings etc. Just do a search.
There is also a useful site here that has a lot of detail.
P.S. Please update your profile with your location - it helps provide accurate replies and information.
