It's been mentioned on this board already, but the Draper tool works! Just received mine from a seller on Ebay UK and turned off that annoying service light. Supposedly it works for the airbag light as well, but I haven't needed to try that yet. I bought it primarily to turn off the airbag light as I'm sure to trip it while dinking around with repairs. Otherwise, I probably would not have bothered with it just for the service light.
If you want to save a few bucks, do not use PayPal to pay for your order...their conversion rate from dollars to pounds is a rip off. I called the seller and payed over the phone with my credit card...probably saved at least $10 not using PayPal.
