🧭 Before you start

Fits: Audi A5 (8T, 2007–2016), Audi A5 Cabriolet (8F), Audi A4 B8 (8K, 2007–2015)

• Timing position: the crankshaft or camshaft is set and locked during this job
• Special tools named: T40311/1, T40311

Don't miss

• With the cable ties it is possible to detach the camshafts together with the camshaft bearings. This prevents components from being interchanged.
• Make sure you do not damage the roller rocker fingers and hydraulic compensation elements when removing the camshafts.
• The cable ties help to keep the camshafts and camshaft bearings straight when they are tightened.

📋 Procedure

1. Remove timing chain from inlet camshaft .
2. Check "“TDC”" position of camshafts:
3. Place camshaft fitting tool T40096 on teeth of inlet camshaft so that the two arms of the tool engage on the two halves of the gear (one in each half, as shown in illustration).
4. Tighten the clamping tool using the knurled wheel so that the faces of the gear teeth are in alignment.
5. Wrap one cable tie (arrows) on each side around bearing pedestal and bearing cap and secure. [Note: With the cable ties it is possible to detach the camshafts together with the camshaft bearings. This prevents components from being interchanged.]

6. Loosen bearing cap bolts in the sequence (12 ... 1). [Note: Make sure you do not damage the roller rocker fingers and hydraulic compensation elements when removing the camshafts.]
7. Carefully detach bearing caps together with camshafts.
8. ⚠ Do NOT interchange components!Do not release cable ties until after re-installation. — Place camshaft fitting tool T40096 on teeth of inlet camshaft so that the two arms of the tool engage on the two halves of the gear (one in each half, as shown in illustration).
9. Tighten the clamping tool using the knurled wheel so that the faces of the gear teeth are in alignment.
10. Fit camshafts and camshaft bearings (secured with cable ties (arrows)) on cylinder head. [Note: The cable ties help to keep the camshafts and camshaft bearings straight when they are tightened.]
11. Check "“TDC”" position of camshafts:
12. Check installation position of dowel sleeves:
13. Fit bolts (1 … 12) in bearing caps.
14. Screw locating pin T40311/1 into threaded hole (1) in line with cylinder 5, as shown in illustration.
15. Place gauge T40311 onto support brackets for clamping pieces (arrows), as shown in illustration.
16. Tighten bearing cap bolts .
17. Check "“TDC”" position of camshafts:
18. Remove camshaft fitting tool T40096.
19. Install camshaft timing chains .
