Oh dear. As I understand it the only way to stop a runaway is to block the airflow. If someone is brave/daft enough would stuffing a jacket/jumper into/against the air intake stop it?

Someone posted on here a short while back to stall the engine would stop it - which means you'd have to sit in it - not for me

And difficult to stall an auto, though not impossible. Agreed, not sure I'd want to get in the car.

I had this happen to my 200tdi discovery on the motorway. Pulled on to the hard shoulder and it just ran and ran. Tried to stall but it just ripped the clutch to pieces.
Ran for about 10 minutes at stupid revs and tons of smoke, basically running on the engine oil.
Scared the Censored out of me.
I got 2 fire engines and a copper called out by a passer by.
Not a nice experience
 life is tooooo short.enjoy the moment.dont worry be happy

Whatโ€™s happening? What causes this?

Okay, got it:

 4/10/18: After 44 Days in the workshop sheโ€™s finally back and I couldnโ€™t be happier to hand that D5 loaner back!
Love the car, but faith in LR Assist and LRโ€™s technical back up has taken a BIG knock Sad

This used to be quite common in older designed engines, quite often they would rotate in the opposite direction, can be caused by carbon build up on the cylinder head in high milage engines, the carbon retains the heat when the engine is switched off and is hot enough to cause combustion.
Going back to the days of rotary arms in distributors of petrol engines, the reason of the rotary arm having a "tail" was to stop engines running away in reverse.
 It can when others can't,
It will when others won't,
It goes where others don't.

Best way is to use squirt a CO2 fire extinguisher into the inlet Thumbs Up

Used the method a few time in the Army when we had tank engines running away dancing down the workshop while on run up using remote umbilicals Laughing

Co2 fire extinguisher into the air intake is a very good idea Thumbs Up I have heard of a coat up against the air intake also works.

You can block the air intake or as Sharky says use a co2 extinguisher, I think I've put this on here before but many years ago was working on a Detroit Diesel V8 2 stroke and it started to runaway, i shouted at the apprentice to try and block the air intake as I went to get a co2 extinguisher, as I was coming back the engine had stopped and I could hear the apprentice screaming, he couldn't find anything to block the air intake so he had sat on it! Shocked This did stop the engine and saved it but in the process it had nearly sucked one of his Censored cheeks off, apparently the next day he had what looked like an 8" love bite on one of his cheeks Rolling with laughter Rolling with laughter

Rolling with laughter Rolling with laughter

If using a coat remove it first. Rolling with laughter

I think the reason a coat is suggested is itโ€™s probably not going to get sucked in. A plastic bag etc would disappear instantly

Blocking air intake doesnt always work and certainly didnt on my 200tdi.
C02 is the way as said.

The older DAFโ€™s were prone to the odd runaway in the past.

This Focus I saw on my Blackvue a few months ago was nearing the end.

Is it fair to assume that even if stopped quickly the engine is toast? Question
