Have followed the instructions for service light reset but not successful.
I have carried out the following:-

1. Turn ignition onto postion II.
2. Remove left diagnostic box top and place jumper in position 7.
3. Press grey button 4 x ~ 1/2 second interval between, (LED comes on each time button pressed then goes out when button released).
4. Wait a couple of seconds (the LED flashes indicating connection to computer?
5. ~ second gap then press grey button once (LED comes on then goes out when button released.
6. ~ a second gap then press grey button 5 x (LED comes on each time button pressed and then goes out when button released
7. ~ second gap then press button once (LED comes on the goes out)
8. Wait a couple of seconds LED flashes.

After disconnecting the jumper and viewing dash the service light is out, therefore, believe success.
However,turn igntion off and then start engine....service light still on.

Any help or guidance on the above procedure appreciated.

Thanks
Peter Burville
