How do you reset service indicator Audi A4?

Press and hold the right button. (odometer reset)

now switch on the ignition

(oil lamp will not flash, but on at all times)

press the right button again

(insp is now displayed)

pull left button. (clock set)

(------ are now displayed)

Pull left button again

This works on my A4 tdi (110bhp) but should work on all. ALTERNATIVELY: Press and hold Service button, switch on the ignition. When the service message appears on screen - press 0.0 (odometer reset). That should reset your 'service!' message.
