Womala Control Valve Solenoid XR858494 for Jaguar XJ XE XF

Product Overview

The Variable Valve Timing Solenoid XR858494 (also known as a camshaft position sensor or VVT oil control valve) is an OE-grade engine management component for select for Jaguar and for Land Rover vehicles with 2.0L turbocharged petrol engines . It controls oil flow to the camshaft actuator, adjusting valve timing to optimize engine performance, fuel efficiency, and emissions . XR858494 is the primary part number for the exhaust position; LR025652 is the Land Rover equivalent . For the intake side, a different part (LR024995) is required .

Key Features

• Controls valve timing – regulates oil pressure to the VVT actuator to advance or retard cam position based on engine speed and load 

• Exhaust position – specifically for the exhaust camshaft on Bank 2 (or compatible positions depending on engine configuration) 

• OE-grade quality – genuine Jaguar/Land Rover specification; available from OE suppliers including Pierburg 

• Direct-fit replacement – plug-and-play installation with factory connector

OE Cross-Reference

💡 Important: This is the exhaust solenoid. For the intake solenoid, order LR024995 .

Jaguar Applications

Land Rover Applications

Engine compatibility: 2.0L L4 Turbo Petrol (204PT / GTDI) 

⚠️ Important: This solenoid is for 2.0L petrol engines only. Not for diesel or V6/V8 variants.

Signs of Failure

• Check engine light – VVT-related DTCs (e.g., P0019, cam/crank correlation codes) 

• Poor engine performance – reduced power, hesitation, or rough acceleration 

• Rough idle – unstable RPM at idle 

• Increased fuel consumption – reduced fuel efficiency 

💡 VVT solenoid failure can be caused by oil sludge blockage or a faulty VVT actuator . Before replacing the solenoid, check the engine oil level and condition.

Critical – Verify Your VIN Before Ordering

VVT solenoids are VIN‑, engine‑, and position‑specific. Variations in engine type (2.0L petrol vs. diesel), VIN range, and intake vs. exhaust position affect fitment. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. When replacing the solenoid, check engine oil for sludge or contamination. Clean the solenoid screen if reusable, or replace as needed.
