Just got through servicing my 2006 A3, and tried to reset the service indicator. Turned on the ignition, pulled out the button under the speedo, and it said "service due in 22 days". According to the owner's manual, if you do this it will reset the service interval to --- and then after driving it, it will indicate the next service in xxxxkms and xxxx days. However, it just won't make the reset happen. I did the same service last year, and reset the service indicator OK. Cannot for the life of me remember what I did, except follow the service book as mentioned above. Any ideas?
