FAQs
What vehicles is this throttle body compatible with?
This D2P throttle body is designed for Opel and Vauxhall diesel vehicles, specifically models like the Astra J, Insignia A, Meriva B, and Mokka, typically with 1.6L and 2.0L diesel engines. Always check the OE part numbers (55496779, 55491244, 55570009, 55578278) against your vehicle's requirements.
Do I need to recalibrate the throttle body after installation?
Yes, most modern vehicles require a throttle body relearn or calibration procedure after replacement to ensure proper idle speed and performance. This is typically done using a diagnostic scan tool.
What are the symptoms of a failing throttle body?
Common symptoms include rough idling, stalling, hesitation during acceleration, poor fuel economy, and illuminated check engine lights.
Can I install this myself?
While physically possible, professional installation by a qualified mechanic is highly recommended. This ensures correct fitting, proper sealing, and the necessary electronic calibration, preventing potential engine issues or fault codes.
How long does a throttle body typically last?
The lifespan of a throttle body can vary depending on driving conditions and maintenance. However, they are designed to last for many years, often the lifetime of the vehicle, unless affected by contaminants or mechanical failure.
What is the difference between this and an OEM throttle body?
This D2P throttle body is designed as an aftermarket replacement that meets or exceeds the performance and specifications of the original equipment (OEM) part. It offers a cost-effective alternative while providing similar functionality and reliability.
Troubleshooting
Check Engine Light (CEL) illuminated after installation
This often indicates a need for a throttle body relearn/calibration procedure. Consult a mechanic or the vehicle's service manual. Ensure all electrical connectors are securely attached.
Rough idling or stalling
Verify the throttle body is correctly seated and sealed. Check for vacuum leaks around the intake manifold and throttle body. Ensure the electronic relearn procedure has been completed successfully.
Poor acceleration or hesitation
Confirm the throttle body is functioning mechanically and electronically. Check for any obstructions in the air intake system. Ensure the correct part was installed for the vehicle's specifications.
Vehicle enters 'limp mode'
This is often a response to critical sensor data. Re-check all connections and ensure the relearn procedure was performed. Professional diagnostic scanning may be needed to identify specific fault codes.

Setup, Compatibility & Care
Compatibility: Before purchasing, verify that this throttle body is compatible with your specific vehicle make, model, year, and engine size. Cross-reference your original part number with the listed compatible OE numbers (55496779, 55491244, 55570009, 55578278).
Setup: Installation should be performed by a qualified mechanic. The process typically involves:
- Disconnecting the battery.
- Removing the air intake ducting.
- Unbolting and removing the old throttle body.
- Cleaning the mounting surface.
- Installing the new D2P throttle body and securing it.
- Reconnecting intake ducting and battery.
- Performing an electronic relearn/calibration procedure if required by the vehicle manufacturer.
Care: Throttle bodies are generally maintenance-free components once installed. However, keeping the engine's air intake system clean (e.g., regularly replacing the air filter) can help prolong its life. Avoid using harsh cleaning solvents directly on the throttle body itself. If issues arise, professional diagnosis is recommended.
