Adjusting assembly mountings - all engine codes except CUKB, CXUA — AUDI

🧭 Before you start

Support the engine in its installed position. Renew the engine mounting bolts one by one and fit them finger-tight, then remove the battery tray, move the earth wire if fitted, and do the same at the gearbox mounting. Lever the assembly until the specified dimensions are reached, tighten the engine mounting, confirm the gearbox support arm and gearbox support edges run parallel, and tighten the gearbox mounting.

Fits: Audi A3 (8V, 2012–2020); platform code 85

Don't miss

• Renew the mounting bolts one at a time so the assembly never loses its location.
• Fit all new bolts finger-tight before adjusting the assembly position.
• Support arm and gearbox support edges must be parallel before the gearbox mounting is tightened.
• Engine codes CUKB and CXUA are not covered by this method.

📋 Procedure

1. Support engine in installation position .
2. Remove bolts (arrows) for engine mounting one by one and renew (if they were not renewed when installing engine).
3. Initially fit bolts hand-tight.
4. Remove battery tray Electrical system27Battery; Removing and installing battery tray.
5. If fitted, remove nut (arrow) and move earth wire clear. [Note: The illustration shows the gearbox mounting for vehicles with manual gearbox 0AJ; it is similar on other vehicles.]

6. Remove bolts (1) for gearbox mounting one by one and renew (if they were not renewed when installing engine).
7. Initially fit bolts hand-tight. [Note: Disregard (arrow and items 2, 3).]
8. Using assembly lever, adjust engine/gearbox assembly so that specifications listed below are attained: [Note: Distance (a) = 10 mm can also be checked with a metal rod of suitable size, or similar.]
9. Tighten bolts for engine mounting.
10. Ensure that the edges of the support arm (2) (on the gearbox assembly mounting) and gearbox support (1) are parallel.
11. Tighten bolts for gearbox mounting.
