Not entirely true. A quick search on the unrelated Sprinter forums doesn't indicate that has ever been an issue to have a warranty claim denied for missing the recommended change interval by a mere 2K.
If you change your own oil (on any vehicle for that matter), you must keep complete and accurate records. It generally means; log, with mileage when oil was changed. I also suggest you keep the receipts showing type, quantity and brand of oil and filter purchased. Make special notes if you had difficuty in doing the warning light reset, ( i.e. you did it at a later mileage) as it may keep in memory, when the system was reset.
There was a seperate thread some time back, on the proper way to reset the maint. Indicator on the Sprinter.
