I'm trying to reset the service interval reminders for Oil, In-Service 1, and In-Service 2.

If I scan the instrument cluster for fault codes, it says that there are no codes, the module does not support fault codes, or there was a communication error.

Following the service reminder interval procedures on the Ross-Tech website I was able to update channel 6 and 7. But 5 would not accept any value, and neither would 8. I would get communication errors, or the value would not set.

Any ideas?

Which VAG-COM version? Which interface?

It's a Ross-Tech HEX-COM, with a version of VAG-COM that is about a year old.

Select Control Module &gt; [Select]
[17 - Instruments]
[Adaptation - 10]

1995-1997 (and maybe part of 98):

Channel 05 should be the distance until the next Oil Service.
It is in thousands of kilometers. Let's say you want the Oil
Service light to come on in 5000 miles. That would be 8000 km.
Put the value 8 into channel 05. The "standard value" used by the US
dealers would be 12 (7500 miles).

Channel 06 should be the distance until the next In-1 Service.
Same units as above. Standard value would be 24 (15,000 miles).

Channel 07 should be the time until the next In-1. In-1 lights
up based on time or distance, whichever comes first. This is in
10's of days. Standard value would be 36 for 360 days.

Channel 08 would be time until the next In-2. In-2 is based
strictly on time. Standard value is 72 for 720 days (about
two years).

If you can't access the module or get connection errors read below:-

The below taken from vag-com site, I have the same issue and have cleaned the pins and it's much better now but needs more cleaning as I still get disconnected often only on 17 Instruments.......

1994-1997 C4 (A6/S6) Instrument Clusters

These have a high bit-error rate. We suspect they use a software-UART and "stretch" bits sometimes. The error-detection/correction logic built into VAG-COM's low-level protocol drivers as of version 0.70 seems to take care of this in a majority of cases, but I still had few reports of customers not being able to communicate with these clusters. In version 0.75 or or newer, please ensure that Char Int on the Options Screen is set to approximately 3 (which is the default). On some PC's, it may be necessary to adjust this value to something other than 3. On very fast PC's try a higher value. On very slow PC's, try something less.

We have received reports from users who cleaned the terminals on the wiring connections at the back of their instrument cluster with electronics cleaner. This appeared to fix the problem with communicating with these clusters.<ul><li><a href="http://www.ross-tech.com/vag-com/audi_issues.html">http://www.ross-tech.com/vag-com/audi_issues.html</a</li></ul>

Can somebody tell me which connectors these are that need cleaning?? Does that mean you have to remove the facia/dashboard??

Is there any other things in the options panel that may be adjusted other than the Char option??
