My A3 2.0 TDI is currently on the 'flexible service' schedule as prior to lockdown I was typically covering 20k miles per year. The car was last serviced in Nov 2019 at about 38000 miles. Due to the lockdown I've not been driving much and the mileage is now around 45000. The onboard computer is saying I don't need a service for another 10800 miles or 182 days. I doubt I will cover the mileage this year but if I leave it for another 6 months it will be almost 2 years since the last service. I guess my question is, should I stay on the flexible service schedule and follow what the computer is recommending or take it in for a service sometime soon.
