Oil Change...FSS did not extend mileage - PeachParts Mercedes-Benz Forum

#1 12-27-2002, 03:36 AM

The last time I decided to an oil change between intervals in my
C 240, the FSS read "8,000 km A Service". After changing the oil, the FSS automatically extended the mileage by 1,600km reading "9,600 A Service.

I decided to do the same this time by chaging the oil betwen intervals. This time, the FSS read "3,200 km B Service". After the oil change, the FSS still read "3,200 km B Service". This time, the FSS did not extend the mileage after oil change like it did the last time. I thought it was supposed to extend to a new mileage, but it did not this time around.

Any ideas?

Thanks,
Johf

There is a maximum mileage that the system will allow for YOUR driving style. You must have reached that maximum.
That happens if you do a lot of around town driving.
The instrument cluster uses imputs other than oil quality & mileage to calcaluate when the next service is needed

are you reseting the fss yourself per the owners manual?

Oh, for Petes sake, DON'T reset it! This car has the Maintenance Commitment Plan, so MB will pay for the FSS services. If you reset it, it will be that much longer (about 10,000 miles) before the thing will call for a FSS service. You'll be ripping yourself off if you reset it. I wouldn't complain about the miles remaining on FSS staying the same, it's a blessing in disguise.
