Anyone found a decent cheap VAGCOM? Able to switch the option for xenons when changing bulbs ect stuff like that?

The only good ones are the genuine rosstech ones. If you can't afford one check out the VCDS owners map and see if someone close to you has one

Post a link of what cable you are talking about

As above, I've had two cheapo ones, we're terrible, wouldn't connect, limited function etc....

 

Bit the bullet and bought a genuine Rosstech cable, its soooo much better, wish I had done from the start (on my 3rd VAG car in a row and wife has a 2012 Ibiza so justifies the cost, in my head anyway).
