audi s4 b7 service reset, not so simple

[seany26]

When trying to do a service reset on my 2005 s4 it gives error upon reading on channels 43,44,45.
Thats;

43 Max Mileage to Service
44 Max Time to Service
and 46 Total Consumption.

also i tried to use the SRI function but only give the option for service reset, and still would not read the mentioned channels.
I should mention that it was on longlife service before and this is the first it has been changed to fixed servive intervils.
Channel Description Unit Current val. New val.
02 Service Reminder Status 0 ---
40 Mileage since Service miles x100 0 ---
41 Time since Service Days 0 ---
42 Min Mileage to Service miles x100 50 ---
43 Max Mileage to Service --- --- ---
44 Max Time to Service --- --- ---
45 Oil Quality 1 ---
46 Total Consumption --- --- ---
47 Soot Quantity km x100 0 ---
48 Thermal Load km x100 0 ---
49 Min Time to Service Days 365 ---

here is the sri function screen.


look forward to hearing a reply

thanks in advance

Ok ive now realised that its only when ive changed to 'fixed' service intervals that channel 43, and 44 cannot be read. when in flexible service intervals it will read these channels ok.
46 connot be read in any service setting.
