A quick google search found this which might help.......Hi!
I tried this after oil change in Boxer 2011 but it's not working. Is there some other way to reset service light?
Thanks in advance!
Procedure for Boxer spanner light it is slightly different but not complicated. However, you should carry out any service that is due and then do a re-set procedure as follows:
* Place the ignition key in the MAR position (1st notch) and wait until the spanner stops flashing,
* Press the trip recorder re-set button for five seconds.
-------The distance remaining to the next service is displayed-------.
* Press the trip distance recorder zero reset button for five seconds to store the operation in the memory.
Important: after this operation, if you wish to disconnect the battery, lock the vehicle and wait for at least five minutes, otherwise the zero re-set will not be registered.
