The electric throttle body (OEM 55496779) is a precision-engineered airflow control unit designed to regulate the amount of air entering the engine on several Vauxhall/Opel diesel vehicles, including Astra J & K, Insignia A & B, Meriva B, Mokka/Mokka X, Antara, Zafira C and related models. This throttle body is electronically controlled and works in conjunction with your vehicle’s engine management system to provide smooth acceleration, accurate idle control and optimal combustion — helping resolve symptoms such as rough idle, poor throttle response, error codes and limp-home mode caused by wear or failure of the original unit. It directly replaces OEM numbers like 55496779 / 55491244 and fits a wide range of 1.6 CDTi and 2.0 CDTi diesel engines when matched to the correct vehicle and engine code.

OEM Number: 055491244, 0817090, 0825048, 817090, 825048, 55496779, 55491244, 55570009, 55578278, 055496779

Key Benefits

 

✔ OEM-Compatible Replacement
Replaces original equipment part numbers 55496779 and 55491244 for direct fitment on compatible diesel Vauxhall/Opel models.

✔ Restores Accurate Airflow Control
Precisely manages airflow into the intake based on electronic throttle commands, improving engine response and idle stability.

✔ Solves Common Driveability Issues
Replacing a worn or faulty throttle body often clears fault codes, rough idling, hesitation under acceleration and “limp mode” related to incorrect air-mass readings.

✔ Improves Engine Efficiency
Correct airflow regulation helps the ECU achieve optimal combustion and fuel-air mixture, potentially improving fuel economy and emissions.

✔ Durable & Reliable Design
Designed to withstand repeated actuation and the harsher conditions inside the intake system of modern diesel engines.

Frequently Asked Questions

Q: What does a throttle body do?
A throttle body controls the amount of air entering the engine’s intake manifold by opening or closing a valve based on electronic signals, directly affecting engine power, throttle responsiveness and idle performance.

Q: What are signs my throttle body (55496779) is failing?
Typical symptoms include rough or unstable idling, hesitation when accelerating, reduced performance, warning lights, or the car entering “limp mode” — often linked to incorrect airflow measurements or sensor errors.

Q: Which vehicles does this part fit?
This unit fits various Vauxhall/Opel diesels, including Astra J & K, Insignia A & B, Meriva B, Mokka/Mokka X, Zafira C Tourer, Antara and similar models with compatible 1.6 CDTi or 2.0 CDTi engines, when the OEM part number matches 55496779 / 55491244.

Q: Do I need recalibration after replacing it?
After replacement, your vehicle’s ECU may require a throttle relearn or idle adaptation to optimise performance; consult a technician if needed.

Q: Can cleaning fix the problem instead of replacing?
Cleaning carbon build-up on the throttle body can sometimes temporarily improve symptoms, but a worn or electronically faulty unit will usually need full replacement for a lasting fix.
