Variable Service Reset
For some models post 2000 MY, variable service reset should be used. To reset the
service interval, enter 00000 into service reset channel 2 to clear the service
counters.
The channels 40, 41, 42, 43, 44 and 45 are used on installing a new instrument pack.
Old values are entered into the new instrument pack to ensure that vehicle servicing
is carried out at the correct intervals.

Login to ECM (VAG Mode11)
Some ECMs may require a valid login code to be entered before allowing some
actions such as re-coding, adaptation values, coding cruise control, A/C etc.
Each vehicle control module has a unique login code that is stored in the 'Vehicle
Factory Repair Manual' or can be obtained from a VAG dealer. The login code is a 5
digit number between 0 and 65535 and is entered via the OmiCheck. If the login is
accepted 'Code Accepted' is displayed, if, however, the login code is incorrect the
response depends upon the protocol:
• KeyWord 1281 - Communication between the OmiCheck and the module will be
broken and the message 'Datalink error, Login lost - Please check the code
entered then retry' (the control module will need to be reset by switching the
ignition off and then on again).
• KeyWord 2000 & CAN - an error message is displayed and communications are
maintained
