LR124526 Oil Pump Solenoid for Land Rover & Jaguar 3.0 TDV6
The LR124526 Oil Pump Solenoid controls the oil pressure regulation system used in Jaguar and Land Rover 3.0L diesel engines. Installed on the oil pump housing, this electronically controlled valve adjusts internal oil pressure according to engine speed, load and oil temperature. When the solenoid fails or becomes restricted by contamination, the lubrication system may produce unstable pressure readings and trigger diagnostic codes such as P0521 or P0522.
The Oil Pump Control Solenoid LR124526 corresponds to OE references LR124526 and C2S52809, fitted on multiple Jaguar and Land Rover models equipped with the 3.0 TDV6 diesel engine. The valve works together with the ECU to regulate the variable oil pump mechanism, allowing the engine to maintain appropriate oil pressure across idle, cruise and heavy load conditions.
In workshop diagnostics, technicians often inspect the 3.0 V6 Diesel Oil Pump Solenoid when oil pressure faults appear despite a functional oil pump and correct oil level. Deposits in the lubrication circuit, electrical coil degradation, or valve sticking can prevent the solenoid from modulating oil pressure correctly.

How the Oil Pump Solenoid Works
Modern Jaguar Land Rover diesel engines use a variable displacement oil pump rather than a constant pressure pump. The solenoid valve regulates internal oil flow to control pump output.
Typical operation process:
- ECU monitors engine speed and load.
- ECU sends electrical signal to the Oil Pump Control Solenoid LR124526.
- The valve adjusts the internal oil bypass channel.
- Pump output pressure changes accordingly.
Benefits of this system include:
- reduced parasitic engine load
- improved fuel efficiency
- controlled oil pressure during cold start
- reduced oil aeration at high RPM
If the C2S52809 Solenoid Valve becomes slow to respond or sticks in one position, oil pressure can become inconsistent across the rev range.
Typical Symptoms of a Faulty Oil Pump Solenoid
Workshops frequently encounter the following symptoms when the oil pump solenoid 3.0 TDV6 begins to malfunction.
| Symptom | Explanation |
|---|---|
| Oil pressure warning light | ECU detects irregular pressure signal |
| Fault codes P0521 / P0522 | Oil pressure sensor signal outside range |
| Delayed oil pressure at cold start | Valve stuck partially open |
| Engine entering limp mode | ECU protection strategy |
| Intermittent oil pressure fluctuations | Solenoid response delay |
In many cases the mechanical oil pump remains operational while the control valve becomes restricted.
FAQ
1. What are the common fault codes for a failing LR124526?
Technicians usually encounter P0521 (Oil Pressure Sensor Range) or P0522 (Low Voltage) when the solenoid fails to respond to ECU commands.
2. Is this a genuine Land Rover part?
This is an OEM-grade aftermarket replacement. It is designed to match the technical performance and dimensions of the original LR124526 and C2S52809 units.
3. Can I use this on a 2.7L TDV6?
While similar in appearance, this specific model is calibrated for the 3.0L V6 diesel engine. Check your OE number before ordering.
4. Why do these solenoids fail?
Internal electrical resistance changes over time, or the fine mesh filters (if equipped) become clogged with debris from extended oil change intervals.
5. How do you ensure quality without a local EU presence?
We implement a 100% end-of-line testing protocol. Each unit is tested for solenoid actuation speed and hydraulic seal integrity before being packed for international transit.
6. What is the typical lead time for bulk orders?
As we manufacture on-site, standard export orders are processed within 7-15 days depending on current production cycles.
7. Is this compatible with Jaguar F-Pace 3.0 diesel?
Yes, it is a direct replacement for the Jaguar XJ F-Pace XF 3.0 diesel oil pump solenoid C2S52809.
