I've had a chat with my stepson and he tells me that when the RAC man turned on the engine, he couldn't turn it off. He had to remove leads under the bonnet to stop it. He also said there was very little oil in it.

Regards
John

That is a runaway caused by excessive crankcase pressure.

Remove the PCV filter it will be choked up solid, top up the engine oil and start it up.

If the engine runs away (uncontrollable throttle) if it is a manual car, then put it into fifth gear and drop the clutch to stall it, if it's an auto, start the car after removing the air intake pipe from the air cleaner box, if it runs away, block the air inlet until the engine stops.


For the price of a gallon of the cheapest oil you can find (10/40) it's worth investigating it properly

If it's a diesel engine and you can't stop it sounds very much like it was running on it's own oil and could have run away until the point it goes bang - that may account for why there's very little oil in it. Whether a turbo failure could cause these symptoms I'm not sure?

when I got my 2.0 cdti back the pcv filter hadn’t been changed since 2012 and blew the oil seals on my turbo and it hydraulicd after I changed the pcv filter thinking that’s all it was. Big cloud of smoke and loud bang
