Hello guys, since I could not really help anyone in the collection thread coding for the A3 I have now opened my own thread. The topic certainly helps other users further. My goal: The oil service and inspection service display should be changed from 15000km/365days to 30000km/730days, so that I have a fixed interval at 30000km/730days. Since I don’t drive 30000km in two years first the time comes to me. That’s how I have handled this since 10 years every 2 years I change the engine oil in connection with the inspection (brake fluid change, interior filter, depending on the KM stand then air filter, spark plugs, DSG oil, Haldex oil,… intervals are in the service booklet). I know that this is not intended because there is either the fixed interval with 15000km/365days or the flexible interval with 30000km/730days and that the system calculates the next oil service on the basis of various factors: The maximum maintenance interval of 30,000 km or 2 years for petrol engines can be reached in driving mode and in most long-distance operation. In extremely uneconomic driving mode or in extreme operating conditions, e.g. short-distance operation, the shortest maintenance interval is 15,000 km or 1 year. That’s a good thing, but I’m not personally interested since I do the service every 2 years, so please don’t have a fundamental discussion about it. Please just comments, At the moment, the values are as follows (have been reset recently): WIV: Oil quality = “good quality” WIV: Min value Km-driving power/inspection = 15000 (km) WIV: Max value Km-driving power/inspection = 30000 (km) WIV: Min value of the time between inspections = 365 (d) WIV: Max value of the time between inspections = 730 (d) FIX: Driving distance since last run performance test. Inspection = 0 (km) FIX: Time since last time-dependent inspection = 0 (d) FIX: Max. driving distance until next runtime. Insp. = 30000 (km) FIX: Max. time until next time-dependent inspection = 730 (d) WIV: Distance from inspection = 0 (km) WIV: Time from inspection = 0 (d) SIA Max. time to service: 365 SIA Max. distance to service: 15000km And this is how the display now looks like: [url= https://data.motor-talk.de/…/209086941-w988-h741.jpg]KLICK[/url] The inspection service is displayed correctly, how can I get the oil service right now My thoughts now: Adjust all min values to the max values, so that there is 30000km/730days everywhere to trick the system, then theoretically there is nothing else left to show the system than 30000km/730days, what do you think about it?
