12242190 – VIRGIN engine ECU for Opel Astra H and Zafira B 1.6 MT35E
The Delphi MT35E engine control unit with part number 12242190 has been electronically tested, professionally remanufactured and prepared in VIRGIN condition. The module is supplied with a Car Pass security code, allowing the required programming and vehicle adaptation procedures to be carried out.
ECU applications
- Opel Astra H 1.6 – selected hatchback, GTC and Estate versions with the Z16XEP petrol engine, manufactured approximately between 2004 and 2008,
- Opel Zafira B 1.6 – selected MPV versions with the Z16XEP petrol engine, manufactured approximately between 2006 and 2008,
- selected vehicles equipped with the Z16XE1 engine, provided that they use an MT35E ECU with matching part numbers and specifications.
Before ordering, compare part number 12242190 and all other markings on the label of the original engine control unit. The vehicle model and engine capacity alone do not guarantee compatibility with the ECU software and configuration.
Common symptoms of ECU failure
- the engine cranks but does not start,
- intermittent engine stalling or difficulty restarting,
- no diagnostic communication with the engine control unit,
- incorrect control of the fuel pump, ignition system or fuel injectors,
- fault codes such as P0230, P1600 or errors indicating an internal ECU malfunction,
- irregular engine operation and fault codes returning despite a correctly functioning electrical system.
Similar symptoms may also be caused by damaged wiring, incorrect power supply, poor ground connections, faulty relays or other components of the engine management system. A complete vehicle diagnosis is recommended before replacing the ECU.
Programming and ECU preparation
The engine control unit is supplied in VIRGIN condition, which means that the immobiliser data from the previous vehicle has been removed. After installation, the ECU must be programmed, assigned to the vehicle and synchronised with the immobiliser system.
Adaptation can be carried out using TECH-2, OP-COM, MDI or another compatible diagnostic tool supporting Opel programming procedures. The process may include entering the security code, immobiliser matching, variant configuration and clearing stored fault codes.
Cloning the data from the original engine control unit is also possible. When the damaged ECU can still be read with professional programming equipment, its software, configuration and immobiliser data can be transferred to a replacement module. A cloned ECU normally does not require additional coding after installation.
Frequently asked questions
Does the 12242190 ECU fit an Opel Astra H 1.6 Z16XEP?
Part number 12242190 is used in selected Opel Astra H 1.6 vehicles equipped with the Z16XEP engine. All numbers on the original ECU label should be compared before ordering, as several MT35E versions were fitted to this model.
Is the MT35E ECU with Car Pass ready to install in an Opel Zafira B?
The module is supplied in VIRGIN condition, but after installation it must be programmed to the vehicle and synchronised with the immobiliser. The supplied Car Pass code allows the required diagnostic procedures to be completed.
How do I program the 12 242 190 engine control unit after replacement?
The ECU can be programmed using TECH-2, OP-COM, MDI or another compatible diagnostic tool. The ECU replacement procedure must be performed, followed by immobiliser matching and verification of the vehicle variant configuration.
Can the original Delphi MT35E engine ECU be cloned?
Yes, provided that the data can still be read from the original module. Cloning allows the software, vehicle configuration and immobiliser data to be transferred to a replacement ECU, which can then be ready for installation without further coding.
Is the 12242190 engine ECU covered by a warranty?
Yes. The module has been tested, remanufactured and is covered by a 6-month warranty. Before installation, the vehicle wiring, power supply, ground connections and controlled components should be checked to eliminate any fault that could damage the replacement ECU.
