Audi A4 service indicator - jcfaeecht
Does anyone know how to reset the service indicator on an Audi A4 without a reset tool.
Or if a tool is required where can I get one at a reasonable price.

Thanks

Audi A4, A6, A8, TT - Resetting Service Reminders
Posted 11 Jun. 2003

Audi has included a Service Interval Reminder that includes oil mileage interval, the service mileage interval, and the service time interval. To reset the Service Reminders using VAG-COM:

Select Control Module > [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).

1998 and Newer:

Channel 02 - set to 0 to reset

Failing this, Stan at German Swedish and French, or Eurocarparts do service resetting tools.

Or borrow one. Good luck.
