    Thank you,

    So before they diagnosed that it was the fuel solenoid immobiliser issue they thought the fuel filter was blocked and that the engine wasn't getting enough fuel.

    It had an intermittent starting issue which the immobiliser I am told can do. So they tried other things before bypassing the immobiliser. So I am thinking they thought the engine wasn't getting enough fuel and did something there.

    Egr valve was stuck open.

    How much should an egr valve bypass cost me?

    So car picked up and feels better.

    They did a egr bypass without needing to use a plate.

    Not that technical but glad its working. Car has power and driving much better.

    So they originally bypassed the fuel solenoid cut of from the immobiliser. That had to be done.

    Ok very strange.

    Car seems fine until you go on a hill and then it almost loses all power, change down a gear and again and you end up in 2nd going 20km/h and you can't go any faster.

    Can't they do a remap. Check wiring to pump is all in place and not broken off.

    OK so they did an egr delete now with blanking plates like I thought they should have done initially.

    Valves were staying open under load. Praying it's now sorted.
