Dangerous Omega! Hi I have just experienced a dangerous full throttle incident on my 03 2.2DTI and could do with some advice please? The car suddenly took off like a banshee in 4th gear (no throttle applied)! switching off the car on the key had no effect. I had to stall the car to get it to stop which frghtened the hell out of me.Luckily I had a clear road & no roundabout ahead. I stoppd in a cloud of  grey smoke, the engine re started on the key but ran away again straight through the rev limiter again only stopping with a forced stall
       Can anyone assist with potential causes? being drive by wire I thought this would be impossible?
thanks  Chris Mac

Sounds to me like the throttle has stuck fully open. Throttle body might need a clean First thing I'd do is to whip it off and have a look.

If its DBW I suppose its possible an electrical/electronic fault is sending a "open fully" signal, but I'd check the physical prossibility first as thats easier than electronics .. to me anyway !!!

If its NOT DBW then its mechanical and should be checkable by removing the input to the throttle body and seeing if the throttle closes ??

This is all based on logic and NOT any knowledge of a TD lump .. I know nowt about them at all ....  so could be totaly wrong !!

Didn't even know if the 2.2 D's actually have a throttle at all?

Hope its not the "Discovery self destruct" problem - oil mist through the breathers becomes enough for the engine to "self-run" on its own fumes..hence why turning off the key made no difference (which should shut off the diesel supply electronically)..

How many miles? What is service history like - I hope not those ridiculous 20k service intevals

sounds like engine wear and when hot starts to burn its own engine oil ,turning off ign will have no effect,

sounds to me ike the seals have gone in the turbo and she is running on her own oil, nasty situation that!!! you were very lucky to stop it as normaly they rev themselves todeath till they run out of oil,

That's the one...for some reason, a lot of LandRover Discoverys are affected...

Had that on a large generator set on board ship many moons ago....  Once we realised what was happening and despite trying all solutions including fuel shutoff and throwing plastic sheeting over the turbo intake, we got to break out the way whilst it self destructed....

What we in that trade called a 'brush and shovel' repair.....

lol know what you mean Brucie, seen a truck engine do it the driver tried to throw his high vis jacket over the air intake to stop it and the engine sucked it in and  eat it and carried on running!!!!!! then we ran!!!!

   Good call....

But how do you squirt it into the intake in a hurry!  I'd either brake to a halt (as Chris did), or run...

I was still thinking of the large stationary Ruston fekker, of a type that used to drive main line trains!

Ruston fekker

And the same to you!

What the heck is one of those?  Google don't help me..
