It’s a good job you were able to stop the engine, otherwise it could have been destroyed from overrevving for long periods of time, and you would have had to fork out a TON of money for an engine rebuild, or possibly a new engine if it was too damaged to rebuild.
I stalled it in 6th to cut the engine, the road speed and break application stalled it. Once the revs dropped to 0k I depressed the clutch again to not strip the gears. I hope that clarifies. I maybe should have made that clear.
Volkswagen Audi group diesels have an ASV. It's there to immediately starve the engine of air when you take your key out - stops the engine from continuing to run on what it can get when you turn it off for an instant engine shutoff, and stops runaways from blowing themselves up.
Good save. I had the same happen to me on an 07 Honda Civic 2.2L CDTi however it was on 175k, injectors filled the sump up, took the turbo out with and stretch the timing chain. Scary stuff, but pulled it over, 6th gear and dumped the clutch.
Lucky the clutch stopped it. In a semi truck it usually burns the clutch. The engine normally produces 1850, or 2250 lbs of torque. And a clutch rated for that. But in a runaway the engine can probably produce 10 times that much.
@@poellot it was a very fortunate situation. The clutch had been replaced in it’s time, I think the paperwork said around 110k, but still that’s a lot of strain on the clutch at the time of the event, because not only is the engine producing a lot of torque like you say, but it’s also going beyond limits to which the engine is set to REV at. I am gutted to have experienced such, but at the same time I’m also grateful to have as well. Had it been an automatic, it would have been a completely different kettle of fish. It’s all good and well saying ‘pop the bonnet and block the intake!’ But who knows what that engine is going to do at that moment in time? Might blow up in your face sending melted bits of engine at you or lubricants, not to mention being on the side of a very busy road which can be quite overwhelming for someone whose never experienced such. Diesels are fantastic engines, but when they go wrong, they do it properly! 😂
@@Coxyboy1994 i just got a 2014 passat tdi. It has an intake valve. If you shut off the ignition it shuts. "Anti shudder valve" they call it. But in the event of a runaway, turning off the ignition should shut it and stop the runaway. I have been a diesel mechanic for years and always worry about a runaway from a turbo seal. Im glad my Volkswagen has a solution for this. If i ever experience a runaway ill know to press the ignition and hopefully the damage will be zero to the engine, replace turbo and clean the intake and have very little cost compared to a blown engine
@@Coxyboy1994 if you have ever been to a truck or tractor pull, you know that erie sound of a diesel running 10 times the rpm it was made for. I have never experienced it first hand but know exactly what it would be like. I hope to never find out if the intake valve on my Volkswagen works as intended but i hope it does if ever needed. It is an automatic dsg transmission.
self revving like that is usually caused by diesel getting into the oil, could either be that your piston rings are on the way out, injector seals are gone or (most likely) it could be that the DPF is failing to regen causing the extra diesel that is dumped into the engine to leak into the oil although, might not be any of those aha
Hi, what exactly was the problem in the end?, I have had the exact same issue and currently waiting on my car being looked at, mine only has 31,000 mls on it and has been well looked after
It's the reason why I'll never get a car with a turbo. So much to go wrong. I've had family members who's turbos in BMW and Audis that have blown and wrote the car off. More hassle than they're worth in my opinion
Yeah sadly just about everything has one these days :/ though, touch wood this is the first time I've ever had an issue with one and the last 8/9 cars I've had have been turbo charged.
Car now finally works. Long story short. Injectors where filling the engine with oil. Causing multiple issues. Turbo was just a victim of that. Broke down in the same way twice after this even after being "fixed". Audi fixed it in the end, the extra cost was worth it as the "dart board" mechanics stopped when they got the car. Real lesson, NEVER buy a car with a limited warranty because the guys who sold this car knew it was a dog and sold a dog with one leg, pretending it had 4. I'm not going to name them because that is pointless, all traders do this. Just make sure when they say the words limited warranty, you say, thanks, but no thanks.
BassVentura pd engine, the injectors are under the rocker cover, when the injector oil seals fail, engine oil leaks past into the injector hole and into the engine, thus engine run away
Hi just read in the description that your car is an Audi 2.0tdi. Have you recently had the emissions fix carried out on your car? If you have Facebook look up VW Emissions Scandal in groups and there is a group with nearly 5000 people all having problems! My VW was having issues with the engine "hunting", took it back and they replaced all injectors free of charge. Not too sure though, not seen anything like this before! Very strange.
When you put the clutch you just let the engine rev max, that's the worst scenario. You should put it in 3 gear of whatever and brake till it dies while trying to turn off the engine
I stalled it in 6th to cut the engine, the road speed and break application stalled it. I had to clutch because I was being pulled, granted not the fasted car in the world but an A6 can bugger off if stuck in "go mode". Once the revs dropped to 0k I depressed the clutch again to not strip the gears. I hope that clarifies. I maybe should have made that clear.
I had this quite scary it redlining by itself I turned the engine off. EGR was caked in dry diesel and DPF blocked. Engine oil was 2 litres overfilled because off failed DPF regens
I'll be honest I'm not 100& sure the engine cut off button did work (Stop/Start). I engaged 6th gear on the pull over and did not release the clutch until about 10-15 mph when I could feel the tightness. So the stall and high gear engine control was probably more effective. A good tip to pass on!
UPDATE: It appears the turbo has gone. Audi have it and they want 2K to fix. I only bought it 06/05/17 so waiting to hear back from the garage I bought it from.
Hey everyone about 3 weeks ago I was on the motorway with my dad and we had a Vauxhall zafira b model CDTI 2006 1.9 Diesel and At that time we had it for about 11 months then the car made a weird noise so we got off at Huddersfield and parked up and the car was releasing blue smoke so my dad turned it off then turned it on and it had runaway engine. We was lucky we had the handbrake on so we didn't move but our car went over Redline so we found out turbo went and sold it for £250 And Now We Have A 2005 Ford Galaxy 1.9 TDI and it made a weird noise and we thought it was the clutch but it was......THE TURBO AGAIN so then we fixed it and now it works fine engine is much quiter and runs smoother.....THE END
Hi, that seems to be working well. You can move car around, on and off transporters etc. But the second transfer of the car had to be winched because the engine kept climbing when you use the throttle. He didn't want to risk it running away with him up the back of the wagon!
HI, i was wondering if you have any bad parking or badly parked clips? i need so content. If so please email me. You will be credited in the video and description. Thanks ParkingFails
could be clutch blue smoke double check AA break down will tell you. And Good luck with your Car. could've if you where driving @ 70-80 mphs it was good time you are lucky .
