Renault Deisel still running with ignition off

Jun 13, 2006 10 Replies

One of our company vans, just conveniently 20 days out of warranty, lunched it's engine on the A3.



Warning lights made the driver pull over but the engine continued running at high revs even with key out, clouds of black smoke till it eventually expired.



Local dealer not very helpful sighting lack of coolant and oil smelling of burning - NO REALLY !! ??



Anyone got any ideas ? Had Turbo failure mentioned, van has had a few warranty issues, cam belt and fan belt pully breaking



Any input appreciated

Running by using the engine oil as fuel.

He's a detective, an' no mistake...

Turbo failure sounds very possible - pumping oil through into the intake.

If it genuinely was low on coolant, that's not impossible as the root cause

- is the turbo watercooled on these? Giving it some hammer on a hot day...

If that is the cause what is to be done in this eventuality??

... stick something in the air intake/exhaust to block them up?

well if the engine is running wild(ie running off the oil at high revs) then do not block the exhaust off, yes you can block the inlet (if you can get to it) but i would not use anything more flexible than a block of wood. there is a lot of suction on the inlet on a high reving diesel.

Stall it. Brakes on, in top gear (at a guess), clutch out. (Dunno about on an auto though).

cheers, clive

Stick it in top, brakes hard on, jump off clutch and stall it?

Trouble is that if it _is_ pumping the engine oil in and running on that, it'll run out quite quickly... and when it does...

Duhhh of course!

Well done :-)

It's not always guaranteed to work. Plus you can end trashing the gearbox, clutch and/or driveshafts.

But it certainly does sound like turbo failure. What model of van is it?

Or you could hold your foot on the brakes untill they go on fire and then roll the car over on a roundabout. Like this bloke

I'm sure this has been done to death before but why the heck didn't he turn the ignition off?? (the BMW twit, not the diesel owner).

Tim

ummm so the oil seals in the turbo start to leak and it blows oil into the inlets ? a bit disturbing that, I wander how broken the turbo needs to be before that happens !
