Note: Pressure values depend on the height and weather. The tolerance ranges apply to an attitude ofabout 300 m.

1)

Check all earth connections in the engine compartment, specifically the connections in the plenum

chamber and on the side members. Look out particularly for possibly twisted or not fully touching cableshoes on the cable ends. Detach the affected earth connections and clean the earth pin and the contactsurfaces of the cables with the contact surfaces cleaner VAS 6410 (even if the contact surfaces seemfine). Reseal the screwed connection with conservation wax (Part No. AKR 321 M15 4).

2)

Remove the engine control unit and take off the plug. Take off the plug on the sender for boost pressureG31/G42 and tie it back. Dismantle the 94 pin connector housing for the engine control unit, seeattachment, and remove the pins for the boost pressure sender G31 and intake air temperature senderG42.

See the current flow diagrams for the precise pin assignments of the cables for the G31/G42 in the 94pin connector housing.

Route the wiring loom along the existing engine wiring loom to the engine control unit. To do this removethe necessary trim and components in the engine compartment. Slot the pins of the wiring loom in theclips of the 94 pin connector housing and refit the 4 pin plug on the G31/G42. Assemble in reverse order.
