Kyllä sen saa ja annan saman ohjeen mikä mullekin annettiin delta-autosta "kato googlesta" 
1. Turn on ignition.
2. Hold down the odometer button (RH side) for either 5 secs (if this is 1st time this has been reset) or 10 seconds.
3. H will appear the 1st and then CFG1, otherwise just CFG1. Press the odometer button again to obatain CFG" and again for CFG3. Select 1 of the 3 as follows: 18000 miles (CFG1), 12000 (CFG2), 9000 (CFG3)
4. Hold down the odometer button again for at least 5 seconds.
5. The spanner/wrench symbol will disappear.
Apparently some other models, say Boxer, etc, you have to hold the odometer button as you switch on the ignition. However, the principle is basically the same.
Hope this is useful anyone out there.
