Post by mech770 » Sun Jun 11, 2017 2:40 pm

Quick how to for timing chain stretch:

Tools needed :
VCDS
Appropriate cable
Laptop

Time taken: 5 minutes

Steps:
1. Key in ignition, Engine off
2. Plug in Cable to OBD2 slot under drivers side dash (RHD)
3. Open VCDS
4. Navigate to engine control Module (1)
5. Click on measuring Blocks
6. Select Blocks 208 and 209
7. Look at column 3 "Idle stabilization
8. Anything from 8 to -8 is fine. Here is the technical bulletin:

P1347/17755 and P1340/17748 related to elongated timing chain. In VAS 5051/5052 if field 3 measurements in display group 208 and 209 are less than -8.0 KW (-9.0 to -14.0 KW) and if both speed sensor and camshaft sensors are OK - Replace upper timing chain

I have been meaning to recheck this actually. Should it be done with the engine cold or warm?
