Installing valve body

–  If it has not yet been done, move selector element -A- to this position. This corresponds to selector lever position “2”.

–  Insert new seals -arrows- in gearbox housing. It is essential to make sure that seals do not slip when valve body is set in place.

–  Fit valve body so that the pin of the selector segment engages in the groove of the spool valve. –  Secure valve body with 2 bolts. –  Remove rubber band from spool valve. The operation of the spool valve must be checked now! –  Shift selector shaft from “2 to 3” and back.

You can continue with assembly if spool valve -arrow- moves as well. –  Valve body must be removed again if spool valve -arrow- does not move as well. –  Tighten bolts for valve body -arrows- hand-tight. –  Tighten bolts to 8 Nm, working from inside outwards.

–  Clip wiring harness for gearbox sensors -3- into retaining tabs -4- provided. –  Push on connectors -1- and -2-. Apply sealant -D 176 404 A2- to valve body cover as follows: –  Cut off tube nozzle at forward marking (nozzle approx. 3 mm Ø).

–  Apply sealant to clean sealing surface of valve body cover as shown. The sealant bead must be t  3…4 mm thick, t  applied on the inside in the area of the bolt holes -arrows-.

Applying a “wider” bead with good intention does not seal “better”, but rather leads to malfunctions.

–  Install valve body cover -2-. –  Tighten valve body cover bolts diagonally in several stages. –  Push breather cap -1- onto valve body cover. –  Install and adjust multifunction switch -F125- → Chapter. Further installation is carried out in the reverse sequence. –  Fill with ATF; check ATF level and top up → Chapter. –  Initiate basic setting in guided fault finding with -VAS 5051-. Basic setting can also be initiated in self-diagnosis with tester -V.A.G 1551-.
