Camshaft Phaser Gear VVT Adjuster compatible with Seat, part number 03C109088E B version. This component is designed for integration into turbocharged engines including 1.4 TSI, 1.8 TSI, and 2.0 TSI configurations within the EA113 and EA888 engine families. The unit provides variable valve timing control to support standard fuel efficiency, throttle response, and emissions functions. Constructed with steel and machined internal parts, it is built to operate under typical engine temperature and pressure conditions. This adjuster features spline geometry and oil passage alignment suitable for chain-driven camshaft systems requiring replacement of the phaser gear assembly. It works with factory ECU calibration without needing software reprogramming when installed correctly. This part helps address timing drift, engine noise, and camshaft-related misfires or limp-mode failures associated with worn components. Not intended for EA211 or diesel engines.
