Required tools
Tools:
•
9900 - PIWIS Tester 3 with installed PIWIS Tester software version 38.900.000 (or higher)
•
Battery charger with a current rating of at least 90 A, e.g. V A S 5 9 0 8 / battery charger 90 A.
NOTICE
Fault entry in the fault memory and/or control unit coding aborted due to low voltage.
•
Increased current draw during diagnosis or control unit coding can cause a drop in voltage, which can
result in one or more fault entries and the abnormal termination of the coding process.

Before getting started, connect a suitable battery charger with a current rating of at least 90 A to the
jump-start terminals.
NOTICE
Control unit coding will be aborted if the WiFi connection is unstable.
•
An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle
communication module (VCI). As a result, coding may be aborted.

During control unit coding, always connect the PIWIS Tester to the vehicle communication module (VCI) via
the USB cable.
NOTICE
Control unit coding will be aborted if the driver's key is not recognized
•
If the driver's key is not recognized in the vehicle, coding cannot be started or will be interrupted.

Place the driver's key with the back facing down into the front left storage compartment in the centre
console to guarantee a continuous radio link between the vehicle and the driver's key.
