Camshaft Adjustment Turning Tool, 2.0L TFSI EA888 Gen. EVO4, T40427

Specialized tool for camshaft adjustment on VAG 2.0L TFSI engines from the EA888 Gen. EVO4 series. Essential during timing procedures where camshafts must be rotated into the correct position before locking.

Compatible with engine codes:
CJXA, DLVB, DMSA, DMSB, DMTA, DNFC, DNFE, DNFG, DNPA, DPAA, DRYA

Function

During timing setup, camshafts must often be rotated precisely to align with locking tools. On these engines, the camshaft adjusters do not feature flat surfaces for conventional tools (e.g. spanners).

This turning tool allows controlled and secure rotation of the camshafts, ensuring correct positioning according to manufacturer specifications.

Mechanical Importance

When camshafts are locked in position, the timing chain remains under tension and may sit loosely between camshaft sprockets. Without proper control, valve spring force can cause unintended camshaft rotation.

This tool prevents such movement, maintaining precise alignment and reducing the risk of timing errors or engine damage.

Reference

OE reference: T40427

Advantages

✔ Enables precise camshaft positioning
✔ Required for correct timing procedure according to VAG standards
✔ Prevents accidental camshaft rotation
✔ Ideal addition or upgrade to existing timing tool kits
