^^^ hmm............ not sure that it's correct to say that the car needs to be taken to the dealer to re-set any aspect of the servicing regime on a mk7.
Fact is that at least for the aspects of car servicing related to distance traveled and elapsed time since last service -ALL of the numbers are accessible to anyone with a diagnostic device that can access adaptation channels in the hex17 module.
The underlying principles for the way that servicing is managed on early model mk7s is like this:
There are 2 x servicing types:
- ESI - this means "Extended Servicing Interval" and it applies if the car has extra measuring equipment that enables the vehicle to calculate a variable service interval based on the car's actual usage. It's possible to switch-on ESI, but the proper calculation needs a car with the PR number “QG1“. The PR number is on the vehicle data carrier.
- FIX - most cars use this facility; the service interval is based on the distance traveled and the time period set by values in the adaptation channels in module hex17 (read below).
For "FIX", there are 3 x parameters for each of the time period and distance traveled like this:
- Time/Distance traveled since last inspection - self explanatory, the number is increased automatically by the car, or it can be set separately by the user
- Maximum Time/Distance until next inspection - this sets a predetermined service interval and generally in Australia the factory values are 365 days and/or 1,500 kms
- Reset value for next Time/Distance-dependent inspection- this facility automatically resets the number in the Time/Distance traveled since last inspection if this is not done by the servicing agent. On most early model mk7's, the factory values used were twice the values in Maximum Time/Distance until next inspection. Note: resetting the value in Time/Distance traveled since last inspection does NOT reset the alarm message that appears on the dash (this is done via a separate adaptation channel)
So - there ain't nothing special about changing any aspect of these channels; it certainly isn't a matter that needs ODIS, or a visit to the dealer
Finally, just to round-off the discussion, here are the factory values for the FIX channels from a MY15 mk7 (from VCDS):
IDE03349-FIX: Max. distance until next mileage-related inspection |
15000 km |
IDE03350-FIX: Maximum time until next time-dependent inspection |
365 d |
IDE03351-FIX: Distance covered since last mileage-dependent inspection |
7000 km |
IDE03352-FIX: Time since last time-dependent inspection |
321 d |
On later MQB platform vehicles, these channels have been deleted:
IDE05931-FIX: Reset value for next mileage-dependent inspection |
30000 km |
IDE05932-FIX: Reset value for next time-dependent inspections |
730 d |
And here is a screen-shot of the same channels from a mk7 using OBD11:

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.
