17 - Instruments IDE03349-FIX: Max. distance until next mileage-related inspection 16100 km
17 - Instruments IDE03350-FIX: Maximum time until next time-dependent inspection 365 Days
17 - Instruments IDE03351-FIX: Distance covered since last mileage-dependent inspection 6800 km
17 - Instruments IDE03352-FIX: Time since last time-dependent inspection 63 Days

When I had my oil changed (that can be reset via the MMI), I went into VCDS and altered the above information to match the oil change intervals (date/mileage). The part that's highlighted (above) is editable.

Thank you !

I don't see the "High Maintenace" option in the "Service Interval" screen. I only have the option to reset the "oil change interval", nothing else. Can you post any pictures of these options?
Thanks

Ok Guys; can someone please explain US A8 D4 servicing for a Brit like me?

My UK A8's service manual has two services; Oil Service and Inspection Service. Exact quotes from the book are "Oil service is every 12 months or 15,000km [9,000 miles]"; "Inspection Service is every 30,000 km [19,000 miles]" - and Yes, I know 2 x 9000 doesn't equal 19,000, but that's what the book says

Do you not have the same two service types in the US/NAR market?

And if so, what are the numbers, please?

Thank you

Julian

LOL, I am confused too. Even the Dealer couldn't explain it thoroughly. My guess it is just like our Lexus SUV (and previous car). The oil change is separate and can be cleared by most "oil change" businesses. The SERVICE DUE can only be cleared by the Dealer and/or with a VCDS (or compatible) unit. The SERVICE DUE message illuminates when it is time to visit the Dealer for them to perform routine services/inspections (wipers, cabin air filter, brake pad/fluid inspection, inspect this, inspect that, blah, blah, blah). I firmly believe it is a money-grab as it forces you to visit the Dealer.

I have two service reminders on my US A8L, one for the oil change and one for "service" both are on a 12 month/10,000 mile counter.

I reset the "service" reminder with my OBDEleven (can't be reset through the MMI) when I change my oil to make that one go away....

Thanks for responding promptly to my query.
So you’ve confirmed that your US market car has both these service intervals set in the instrument panel as 12 months / 10,000 miles, but:

1] What does it say the intervals are in the US market service book?

2) Do you set values in miles or kilometres? I ask that as although we use miles on our instrument panel and throughout the MMI screens in the UK, when you look at or adjust the values in the Instrument Panel control unit using VCDS, the units are actually stored as kilometers; the MMI converts them for display purposes...

And just for interest, find below photos of Service book extracts for the two service types and a picture of my MMI 'Service Intervals' screen from my 2015 A8.

Note: My Oil change numbers in the MMI look wrong because I don't actually use Fixed Interval oil changes myself. My values are based on the Longlife Oil changes that are based on 2 years, up to 18,000 miles

Sorry Dave, I don't believe this is totally accurate. Unless the US is totally different than Europe, I believe the IDE 3349-3352 values are used to set [3349/3350]and measure [3351/3352] the values for the Inspection Service only! It's confusing in the US as I believe Oil and Inspection are synchronised to be performed at the same time whereas they are different time periods in Europe!

The story of what variable is used for what is quite complicated, though, as I found out when I had to check all the values because my local UK Audi dealer has messed up all my service values giving me premature warnings.

My investigation reveals that the following ECU 17 - Instrument Panel values are used for Service on the A8 D4.

Some of those variables are used in Europe for our 'Extended Service Interval' option, where we can go for up to 18000 miles and/or 2 years before an oil change using appropriate 'Longlife' oils. 'Extended' or 'Longlife' service is selected by setting 515-Oil quality to 'Good'; fixed servicing as used in the US is selected by setting 515-Oil Quality to 'Poor'. Most of the ESI settings are used for the Extended Service but some ESI values are used even when 'Longlife' is not selected. Since I use 'Longlife' here in the UK, I can't see what happens to the values for Fixed servicing as when I check using VCDS, I obviously get values related to my choice of Longlife. I'd be interested to see what values are used and changed over time from someone who has VCDS in the US with Fixed servicing.

But here's my guess for what you might see for Fixed servicing:
1153-SIA is used to SET distance between OIL services - I'll guess as 9000Miles
1154-SIA is used to SET time between OIL services - I'll guess as 365 days
3349-FIX is used to SET distance between INSPECTION services - I'll guess as 9000miles
3350-FIX is used to SET time between INSPECTION services - I'll guess as 365 days
0515-ESI is used to select FIXED servicing by setting to POOR

The following variables are checked for servicing and set the 'Service' indicator
0510-ESI is used to check Distance for next OIL service
0511-ESI is used to check Time for next OIL service
3351-FIX is used to check Distance for next INSPECTION service
3352-FIX is used to check Time for next INSPECTION service

VCDS users can see what's going on over time in two ways:
1) You can invoke the Service Reset button on the main menu; although this option implies that a reset will be done, the first step will just go and read the values. [Note: currently VCDS doesn't read and show all the values I've mentioned, but I believe it's some of the Extended Service values that are missing]
2) You can run an Adaption Value map by selecting the VCDS 'Controller Channel Map' button and selecting 17 as the controller address, ticking 'Adaptation' and selecting CSV file. [The file generated will show all values from the Instrument panel]
