A matter of days after getting the car MOT’d and serviced sods law dictated that a fault would occur. Moments after getting the car valeted it threw an Airbag warning light, fortunately a few weeks ago I purchased an OBDII code reader. This was its first test, plugged in and within seconds had tracked down the fault code (a dodgy igniter drivers side airbag), cleared it and the warning light disappeared and hasn’t returned. It cost about £80, so wasn’t the cheapest one, they start at about £20, but go up to £400+.
Many of the cheap ones have poor reviews, but this one said it worked as expected in pretty much every review, so I thought why not. This is specifically a VAG one, rather than a generic reader and works rather well. No need for batteries as it is powered by the OBDII socket and it boots up in seconds, like 1 or 2 seconds. Recommended? Yes if you have a Volkswagen, Audi, Seat,Skoda or Lamborghini.
