l  1) Also secures starter l  2) Property class 10.9. The steel bolt may be re-used as often as necessary. l  3) Aluminium bolts must not be used more often than twice → Anchor.

The aluminium bolts -2 … 11- must not be used more often than twice. After the first use, the bolts must therefore be identified with an „X“ made by two chisel marks -arrow-. To avoid damaging the bolts when making this mark, do not clamp them directly in a vice. Clamp a 14 mm socket with 1/2" drive in a vice and insert the bolt as shown. Bolts already marked with an „X“ must not be used again. Procedure   Note t  Renew the bolts tightened with specified tightening angle. t  Renew self-locking nuts and bolts as well as seals, gaskets and O-rings. t  Do not remove plugs or protective caps until you are ready to fit the relevant line. t  Secure all hose connections with the correct type of hose clips (same as original equipment) → Electronic parts catalogue. t  Fit all cable ties in the original positions when installing. –  Before installing gearbox, remove residue from threaded holes for engine/gearbox bolts in cylinder block using a thread tap.

–  The following preparations are required before joining engine and gearbox. –  Insert assembly aid -T40169- into gearbox housing and clutch module/dual-mass flywheel from below, as illustrated. l  The assembly aid -T40169- must engage in the semi-circular recess -1- and in the inspection hole -2-.   Note There is only one inspection hole on the circumference; turn the clutch module/dual-mass flywheel accordingly. –  Insert pin of assembly aid into hole on gearbox housing.

–  Insert transport lock -T40170- into gearbox housing from below and clamp onto flange shaft -1-.

–  Check whether dowel sleeves -A- for centring engine and gearbox are fitted in cylinder block; install missing dowel sleeves. –  Check whether aluminium bolts securing engine to gearbox can be reused; if so, apply marking → Anchor. –  Bring gearbox into position on engine and tighten bolts -1 … 11-. –  Remove transport lock -T40170- and assembly aid -T40169-.   Note

The following step is necessary to ensure that the clutch module/dual-mass flywheel is straight and that it makes even contact with the drive plate. –  Use assembly lever -1- to press clutch module/dual-mass flywheel -2- slightly against drive plate -3- in direction of -arrow-.

–  Bolt clutch module/dual-mass flywheel onto drive plate as follows:   Note Use ring spanner insert AF 16 -V.A.G 1332/14- to tighten bolts. –  Hand-tighten first bolt -arrow- (2 Nm).

–  Insert guide pin of adapter -T40058- as follows: l  The larger-diameter section -arrow 1- faces towards the engine. l  The smaller-diameter section -arrow 2- faces the adapter.

–  Turn crankshaft 180° further in normal direction of engine rotation -arrow- with adapter -T40058-.

–  Tighten bolt accessible in this crankshaft position -arrow- to specified torque → Rep. gr.34 or → Rep. gr.37. –  Turn crankshaft by 60° each time and tighten remaining 5 bolts to specified torque → Rep. gr.34 or → Rep. gr.37. –  Hold ATF lines in installation position when joining engine and subframe. –  Install engine support and engine mounting → Chapter. –  Bolt drive shafts (left and right) onto gearbox flange shafts → Rep. gr.40. –  Vehicles with multitronic gearbox 0AW: Install ATF lines → Rep. gr.34. –  Vehicles with dual clutch gearbox 0B5: Install ATF-lines → Rep. gr.37. –  Install particulate filter: t  Vehicles with manual gearbox/multitronic gearbox 0AW → Chapter t  Vehicles with dual clutch gearbox 0B5 → Chapter.

Vehicles with manual gearbox or dual clutch gearbox 0B5: –  Raise engine/gearbox assembly using scissor-type assembly platform -VAS 6131 A- only until distance between tunnel cross member and body is -a-. l  Dimension -a- = min. 100 mm. –  Vehicles with manual gearbox: Install selector rod and push rod → Rep. gr.34. –  Vehicles with dual clutch gearbox 0B5: Install selector lever cable → Rep. gr.34. All vehicles (continued): –  Raise engine/gearbox assembly using scissor-type assembly platform -VAS 6131 A-. –  Align subframe and tunnel cross member on longitudinal members according to markings made before removal. –  Tighten subframe bolts only to specified torque (do not turn further); the bolts are only to be fully tightened after performing the wheel alignment check → Rep. gr.40.   WARNING Risk of accident because of loose bolt connections. Do NOT drive the vehicle unless the subframe bolts have been finally tightened. –  Tighten bolts for tunnel cross member → Rep. gr.34 or → Rep. gr.37. Remaining installation steps are carried out in reverse sequence; note the following: –  Vehicles with four-wheel drive: Install propshaft → Rear final drive 0BC; Rep. gr.39 or → Rear final drive 0BF and 0BE - sport differential; Rep. gr.39. –  Vehicles with manual gearbox: Install slave cylinder → Rep. gr.30. –  Install front cross member → Rep. gr.66. –  Vehicles with multitronic gearbox 0AW: Install selector lever cable → Rep. gr.37. –  Secure intermediate steering shaft on steering box → Rep. gr.48. –  Install subframe cross brace, upper suspension links, anti-roll bar and, where appropriate, diagonal struts; secure suspension strut to track control link → Rep. gr.40. –  Install brake calipers → Rep. gr.46. –  Install engine control unit → Rep. gr.23. –  Install filler neck for washer fluid reservoir → Electrical system; Rep. gr.92. –  Electrical connections and routing → Current flow diagrams, Electrical fault finding and Fitting locations. –  Install electrical wiring, terminal 30 wiring junction 2 -TV22- and cover for electronics box in engine compartment → Electrical system; Rep. gr.97. –  Install refrigerant lines → Rep. gr.87. –  Observe notes on procedure for connecting the battery → Electrical system; Rep. gr.27.   Caution Risk of irreparable damage to control units because of excessive voltage. Never use battery charging equipment for boost starting. –  Install air cleaner housing → Rep. gr.23. –  Install lock carrier cover → Rep. gr.63. –  Install plenum chamber cover and strut for lock carrier → Rep. gr.50. –  Fill up with engine oil and check oil level → Booklet811, → Booklet812 or → Booklet818. –  Connect coolant hoses with plug-in connector → Fig.. –  Fill up with coolant → Anchor.   Note t  Drained-off coolant may only be used again if the original cylinder head and cylinder block are re-installed. t  Contaminated or dirty coolant must not be used again. –  Bleed fuel system → Rep. gr.23. –  Charge refrigerant system → Air conditioner with refrigerant R134a. –  Install wheel housing liners → Rep. gr.66. –  Fit front wheels → Wheels and tyres; Rep. gr.44. –  Perform wheel alignment check → Rep. gr.44.   WARNING Risk of accident because of loose bolt connections.
