Would that not be the fuel solenoid? I am not familiar with the newer engines but I believe all diesels will run on without a fuel shut off as no ignition is required....
fuel solenoid or running on own oil.

Running on own oil? not sure what you mean. Right - either way it needs sorting - I shall investigate, thanks for narrowing it down.
do a you tube search for "engine runaway"

A compression ignition engine will run on any heavy oil that finds it's way into the cylinders, including it's own engine oil.

Hi
Don’t think the Puma has a solenoid - I had someone suggest a wiring problem....perhaps in the break lights

Thanks, that is helpful. Will take to garage man. Just what i need at the moment!

It is usually caused by engine oil entering the intake tract from worn turbo seals, or by overfilling, or by oil getting into the intake tract via breathers.

I have had the EGR valve stick and then fix itself. Had a break light go, but was just a bulb and have replaced it.

Hi
Let me know what he says....I had mine in and the garage changed the ignition switch. Did it again today! I’m going back anyway as I’m having a problem with the drive belt. So will be asking them to check wiring - someone informed me to check the break wiring.
egr can be disabled thru remap.

My defender has done 67000. It seems a common problem but it’s different wiring issues. Some scary comments on here! I am driving still. A runaway does not need the ignition and it’s not about the electrics but other problems.....also rare! It’s easy to scare.
The brake pedal has two switches, one for the brake light and one connected to the ECM. Not sure what the one connected to the ECM does, but half recollect that it reduces engine power when the brakes are applied (as said, not sure). I suspect this switch is faulty enabling the engine to run on until the brake pedal is pushed. Its a possibility.
not scaring - just making aware.

Cheers sounds sensible
What are You thoughts about the runaway comments?
