Complaint in M112K: P2032 and/or P202E stored in ME control module of M112K engine

Remedy: Use Kit part no. A112 141 03 25

Remove the throttle valve from the supercharger. Refer to WIS document AR07.51-P-1401SVK.
Apply contact "Santovac" from kit with paintbrush to the contact pins of the connector at the engine harness, wait approximately 10 minutes to allow it to dry.
From the kit, install throttle valve with wiring adapter and dampening.

Complaint in M113K: P2032 and/or P202E and/or P208E and/or P208F stored in ME control module of M113K engine

Remedy: Use both Kit part no. A113 141 06 25 and part no. A113 141 07 25

Exchange the original throttle valve actuator with the throttle valve actuator from Kit A113 141 06 25 - refer to Remedy for M112K steps a, b and c.
Remove the original re-circulating air valve. Refer to WIS document AR09.50-P-8843T.

Start screws only of the re-circulating air valve first, then mount the supercharger rigidly.
Tighten front screws of the now aligned re-circulating air valve first.
Remove supercharger again. Refer to WIS document AR09.50-P-47055SVK.
