Full disclosure, I'm not using VCDS, using a TopDon scan tool with advanced vw/audi coding/adaptation capability. I do not have the service due message, only the reminder, all the damn time - when switching ignition on and then off. I also don't have a wrench icon in this A5 cluster. Not a feature.
Oh I see. Yeah so essentially the same thing as us then. I really struggled with wondering if my TT was always like this...like it's supposed to do that, but I wasn't sure hence why I made this post originally. However with only one other person (now two) saying they encountered the same I'm thinking indeed something is amiss--though again it's not really so bothersome
to me that I really care about it. The actual service required/due reminder still works as it should, it's just kind of the indication of when service is due coming on all the time (instead of "close" to the interval) that's the thing that's not right.
I wonder if this has anything to do with the variable oil service and fixed. How would you actually 'switch' the car from fixed to variable or vice versa? Is it just the oil quality = 2 value?
Yes but you still have to fill in some other values that wouldn't be populated at all in the fixed mode. With VCDS you get the full rundown and you can kind of switch between each type to see what it
would change things to if you select the "change to flexible" or "change to fixed" options--basically it gives you a preview of the values (which you can also then set to custom values) before you actually write/program them.
The thing is I never fooled around with the variable intervals on the TT so I don't think it's related to this. On a side note I
did set it up to see if it worked on my A3 (and it def. does) but again that car doesn't show the reminder in the same fashion. That car is actually set to flexible right now and it's working fine. It hasn't yet gotten to my personal "regular OCI" of 8,000km (5,000 mi) and I do plan on changing it at that point anyway but I was just kind of fooling around with the flexible to see how it worked and what it recommended--as said it works, anyway. I think the only thing you need to make sure this works is the oil level/temp sensor in the pan (some lesser model cars in the US/Can market don't have this hence why they say you shouldn't enable it on these cars). That and of course to make it work correctly in practice you should use a 507.00 oil (or a 511.00 oil should be good too)--you're not supposed to use with 502.00, which is what the "oil quality" thing refers to. It's really not about the oil quality it's about the SAPS, but that's an entirely different topic haha.
Here is what I have:
002 Service reminder - stuck at 2 (attempting to switch it to 0 says 'adaptation successful', but the value does not change!)
OIL (minor maintenance)
040 Mileage since service - 0 (x100km)
041 Time since service - 0 (day)
042 Minimum mileage to service - 140 (x100km) = 14,000km
043 Maximum mileage to service - 150 (x100km) = 15,000km
049 Minimum time to service - 350 (days)
044 Maximum time to service - 365 (days)
045 Oil quality - 1 (normal quality, 2 is for flexible service?)
047 Soot entry - 0
048 Thermal Load - 0
050 Basic distance value for oil change with fixed service interval - 150 (x100km) = 15,000km
051 Basic time value for oil change with fixed service interval - 365 (days)
Inspection (Major maintenance)
052 Basic distance value for inspection - 300 (x100km) = 30,000km
054 basic time value for inspection - 730 (days)
053 Distance since inspection - 0 (x100km)
055 time since inspection - 0 (days)
-At one point I had 042 and 043 pair set to the same value, as well as 049 and 044. I figured maybe that was the problem, and I needed to create a range of distance and time which influences when the reminder displays, but still nothing.
-Then I figured I would force the system to display service due by setting 040 and 041 beyond the threshold, and it does display service due. Then I went into 002 and it was still set to value 2. I tried to input a 1 value (which is service reminder on) but adaptation fails. Tried 0, did not change to 0, still stuck at 2.
I can't really remember what was supposed to be set to what--so many values and I only really would know when I'm looking at it but I had
thought you're not supposed to have both min and max values for fixed, it should be only one (I think max) but again I can't remember so take that FWIW.
As a question, when you're resetting this with your TopDon, is it an automated process that does this (or can you use such a process on it)? Or are you just setting each value individually/manually? In that case I'd suggest changing the 002 value
last, after changing the others.
However all that said, TBH I don't think it has anything to do with these values. As said I've tried the resetting in VCDS, tried comparing to my A3 and everything works right and looks exactly the same in terms of these functions and the values shown in VCDS. My thinking has always been this is something completely separate, like some
other adaptation value or coding value...most likely in Instruments but even possibly elsewhere (making it harder to pinpoint). But yeah I don't think anyone can say...until they find what it is. As said I kind a just gave up on this, lol, 'cause it seemed like it was going to be way more work for what to me is "the smallest little thing" that honestly doesn't bother me any more than me simply
knowing it's "not really supposed to do that". Functionally/operationally, it doesn't really mean much.
