–  Support subframe with engine and gearbox jack -V.A.G 1383 A- as shown in illustration.

–  Mark installation position of subframe on longitudinal members with felt-tip pen. –  Unscrew subframe bolts -1, 2 and 3- on both sides in stages and in diagonal sequence.   Caution Risk of damage to parts of the running gear. Do not let the vehicle down on the wheels if the gearbox mounting, steering box and subframe cross brace are not properly installed. –  Using engine and gearbox jack -V.A.G 1383 A-, lower subframe only far enough to remove bottom ATF line; ensure sufficient clearance for hydraulic hoses (left-side) and electrical wiring (right-side). Installing Installation is carried out in reverse sequence; note the following: l  Tightening torques → Chapter „ATF cooler, ATF lines and ATF filter“   Note Renew O-rings   Caution Risk of damage to gearbox t  All plugs from engine bung set -VAS 6122- which were inserted in ATF lines and gearbox when dismantling must be removed. t  If you forget to remove the plugs, the ATF cooling will be ineffective and the gearbox will be damaged. –  First press ATF lines onto gearbox and cooler by hand until they engage, then bolt on. –  Press retaining clips onto ATF line connections and then pull to check that clips have engaged properly. –  Check ATF level and top up as required → Chapter. –  Align subframe on longitudinal members according to markings made before removal. –  Tighten bolts for subframe to torque setting only, do not yet turn further (wait until wheel alignment has been carried out) → Running gear, front-wheel drive and four-wheel drive; Rep. gr.40.   WARNING Risk of accident if bolted connections are not tightened. The vehicle must not be driven if the subframe mountings have not been fully tightened to the final setting. –  Install anti-roll bar → Running gear, front-wheel drive and four-wheel drive; Rep. gr.40. –  Install electrical wiring → Current flow diagrams, Electrical fault finding and Fitting locations. –  Observe measures required after connecting battery → Electrical system; Rep. gr.27. –  Secure intermediate steering shaft to steering box → Running gear, front-wheel and four-wheel drive; Rep. gr.48.
