Sorry, my mistake, car was last serviced 03 Feb 2021 by VW agent, just before the W agent MOT'd the vehicle. At the time I asked for the service interval to be set correctly. They said, after the service, that the car was "all ready to go". I, incorrectly, assumed this meant they had reset the service indicator as I had requested.
I find that the indicator is still coming on in Sept 2021. I emailed them this weekend asking for the interval to be set to 12 months from when they last serviced the vehicle (Feb 2022 - presumably this is the date that one would calculate from the online FSH record that I have not seen) and they replied today saying the service indicator interval could not be changed. However, they said that, if I pop the car in, they could switch it off (presumably until next September) which means that the service indicator would not come in when it is due in Feb 2022.
All I want on my car is a service indicator that is correctly set to take into account when the car was last serviced. I don't think that is an unreasonable request.
It should not be VW policy to have people ignoring warning indicators or to install systems in cars that do not warn at the appropriate time.
