Had a recurring airbag light fault light up a couple of times now. Had it reset by kind sould with VAG COM but haven't really felt inclined to invest in the system / laptop myself. Went for one of these tools on eBay instead. Cost just £18 plus p&p. And I've got to say - it does what it says on the tin! Not going to diagnose much in detail (though I do have a 'Mixture adjustment control' fault code too). Seems to just do Engine codes, ABS codes, Airbag codes and auto transmission codes. Mine is a '99 A3 1.8. I'd recommend it if anyone needs lights resetting on the cheap! Mine is the U280. Just thought others might like to know.
