This procedure details how to
install a NEW Instrument Cluster in Immobilizer-equipped VW/Audi vehicles
with Immobilizer II . As of 11 Mar. 2002, VW and Audi
are providing 7-digit Secret Key Codes in place of the earlier 4-digit SKC's. Keys must be coded using the new 7-digit SKC (secret key code)
method unless the owner still has the correct 4-digit code. VW stopped
giving out PIN/SKC information at all in 2005.
Immo-3 knows your car's VIN.
Access 17-Instruments (or separate 25-Immobilizer on vehicles that are set
up that way) and look at the first "Extra" field.
If you see something like: "Immo-ID VWZ7Z0W0648696" You've got
Immo-2 (or maybe even Immo-1 in earlier non-US models).
If you see something like "WVZKB58001H231169 VWZ7Z0W0648696" You've got
Immo-3. The first 17-digit string is the VIN. The second 14-digit string
in the Immo-ID.
Important Note:
Unless you ALREADY have the SKC information for your vehicle and
components then you will NOT be able to do any of the Immobilizer
functions.

--- Entering the Mileage in the New
Cluster ---
-
If you are live in a market where the odometer reading
is in miles, you should change to km before entering the mileage. To do
this, consult the Factory Repair Manual for your vehicle. Here is an
example:
[Select]
[17 - Instruments]
[Recode - 07]
Change the 3rd digit from a "2" (US) to a "3" (Canada)
[Do It!]
Confirm that the odometer in the car now shows kilometers, not miles.
-
[Select]
[17 - Instruments]
[Adaptation - 10]
Enter "channel number" 09 to select channel
Put in the number of km divided by 10.
Example: If old cluster had 50,357 km, put in 5036.
Note: Some clusters may require a Login of 13861 before you can set
the mileage.
[Test]
Observe the Instrument Cluster and make sure the mileage displayed is
correct. Once you save this value, you will be unable to change the
mileage EVER!

-
If you are live in a market where
the odometer reading is in miles, you should now change back to miles. To
do this, consult the Factory Repair Manual for your vehicle. Here is an
example:
[Select]
[17 - Instruments]
[Recode - 07]
Change the 3rd digit from a "3" (Canada) to a "2" (US)
[Do It!]
Confirm that the odometer in the car now shows miles, not kilometers. Make sure that the mileage reading
is correct.
