No commission! I've no idea who these guys are that distribute the leads (there are several about, I just suggest going for the cheapest on e-Bay) but it seems that every other new thread relates to someone needing to arm themselves with this cheap bit of kit, hence at risk of sounding repetitive I say "see my thread on tester for tenner and a laptop".
My own story is that I had the airbag warning lights on for a couple of years and begrudged paying £40-£50 for a professional to extinguish them (OK, they probably paid £2000 for a Snap-On set-up with bells and whistles for all makes of car and need to recover it). I actually got a VAG-COM lead recently to try to bottom out a poor starting issue (which I still haven't fixed). However, the lead, with the link added between pins 7 to 3, allowed me to turn out the airbag lights, so in that regard, it has paid for itself already. Now... back to the poor starting....
