INFORMATION

The VANOS central valve and corresponding fastening bolt, located at the gear-driven end of each camshaft, can consist of three different design versions since the introduction of the "B" designation 3 and 4 cylinder modular engines as of 5/2014. The third design version was fully phased in by 5/2018.

The central valve must be compatible with the camshafts and the VANOS actuators within the same production period. The central valve fastening bolt diameters and thread pitch changes with each central valve version, preventing it from being assembled correctly if components are mixed from a different version.

Determine the VANOS hardware versions before ordering any replacement parts.

Remove the VANOS actuators (refer to Repair Instruction 11 36 655 "Removing and installing/replacing both actuators").
Locate the VANOS central valve Part Number (P/N) per the table below.
Confirm the P/N shown in the illustrations below using ETK (EPC electronic parts catalog) or AIR per the vehicle's production date.

All three of the VANOS central valve designs are shown (circled), though only one design is utilized per engine.

NOTE: If the VANOS central valves, VANOS actuators, or camshafts are replaced due to valvetrain repairs:

Use the matching date ranges shown in ETK
If the integration level is 18-03-500 or higher: No programming is required.
If the vehicle Integration level is lower than 18-03-500: Program and code the vehicle using the ISTA 4.10.13 or higher.

NOTE: If the cylinder head needs to be replaced, the new head will be delivered with camshafts designed for either the "short" or the "deep-drawn" VANOS central valves. Make certain to order and install the corresponding, matching VANOS adjusters and VANOS central valves (refer to ETK)
