Only the company’s two most well-known vehicles, the Vectra and Omega models, were equipped with the 2.0-liter Opel X20DTH or LD1 diesel engine, which was manufactured between 1997 and 2000. The unit’s Y20DTH index changed after it was upgraded to Euro 3 environmental standards.
The X17DTL, X20DTL, and X22DTH engines are also part of the X family.
The engine was mounted on:
- Opel Omega B (V94) in 1997 – 2000;
- Opel Vectra B (J96) in 1997 – 2000.

Disadvantages of the X20DTH engine
The Bosch VP44 high-pressure fuel pump’s malfunctions are the main cause of the car owner’s issues;
Fuel pump control transistor burnout is the most frequent cause of failure;
This is where the system will simply air out if the fuel filter is replaced incorrectly;
Because the gaskets beneath the nozzles are drying out, oil and diesel fuel can be combined;
Additionally, the particulate filter is clogged or soot frequently wedges the EGR valve.
