  1. If you run the engine with the MAF sensor plug disconnected then it will run at a default setting which is close to where is should be so if the engine then runs well you know its the sensor.

    If it doesn't make any difference then I would be looking elsewhere.....possibly turbo variable vanes gummed up with carbon is a popular one for these symptoms

  2. Seems like these errors relate to coding issues and/or CanBus communication errors.
    You may have to dig a lot deeper with some more serious diagnostic equipment to come up with more information.

    However, if the battery condition is poor and the charge level low then this could result in the Power Steering fault you describe, maybe replacing the battery if needed will resolve this issue

  3. only other thing it can be is the wiring to either the coil or the injector

    Inspect the wiring and the plugs onto each component for security, damage or corrosion

    Alternatively, see if swapping the components to another cylinder puts the fault onto that cylinder instead

  4. Sounds like a very rare car indeed and hindsight is a wonderful thing (i wished i had kept half the cars I owned over the years).

    Obviously the Police force then went over to Ford cars for cost reasons I would imagine.
    I think the 2.6 was the European 'Opel' engine range but would have been more tuneable than the 3.0 litre possibly?

  5. The trouble with cooling systems is that once you fix a leak the pressure then goes to the next weakest point so potentially it could have gone within the engine (you don't state whether petrol or diesel engine - different tests for each one to determine if engine is leaking internally).

    I would definitely start with replacing the Coolant Pressure Cap as if this is weak then the pressure drops and can lead to higher temperatures which boil off the coolant and also to allow air to enter the cooling system. Very cheap and easy part to replace to start with the diagnostic process.

    From there I would go with a pressure test to see if the pressure drops within the system and also to see if it is leaking externally under pressure.

    After that then it is a case of internal engine investigation but even then this can be done without too much dismantling of components
