Deletes known airbag failed Gölfen

I've used it to read out errors in my golf 4 cabrio the side airbag well known and clear. In addition I have dealt with the battery disconnected the plug under the seat with contact spray and re-plugged. The warning light remained on course thus yet. So the stored error had to be deleted, which was a matter of 2min with this device. Class. Error cleared, warning light stays off. Airbag doing. A lot of money saved. Once read errors can (without elimination and cancellation costs at VW already 25 pounds). Has therefore made already paid.
