This might sound like a crazy post. Perhaps it really is. I am interested to know if there's any way to cause a DSG to stall in some kind of emergency. The thing that comes to mind is when a turbo is blowing a gasket and the car is starting to run on the oil from the sump. Normally the car will rev out uncontrollably because its no longer under the control of any electronic management systems. It will clearly fail if it goes beyond the red line, which it will eventually do as the oil seal comes apart and the oil is sucked through the turbo into the engine. So the car will start to drive faster and putting one's foot on the brake is going to be a hard way to stop the car but will eventually be brought to a very hot stop, at which point the transmission clutches disengage leaving the engine to fly apart in seconds. In this scenario, one can stall a manual car, but ordinarily a DSG is not going to allow that. So I thought I would ask the many knowledgable people in this place if any of you has ever found a way to do it?

Turn the ignition key to the off position, the ASV should starve the engine of air and stop the runaway condition.

Is it really as simple as that? Surely the air can still get through can it not?

In all the years of cruising various VAG forums I've never heard of this happen (dsg or not) if it did happen to me, the last thing I'd be concerned about is trying to save/stall the gearbox as the engine will be goosed. 

 

Years / decades since I never did this.    But you could go away from the front where the bits of metal might be coming from and shove a potato up the tail pipe.

Surely the engine isn't goosed until it goes bang?

Hi Toot,

 

Where are the bits of metal coming from? Do they come out or off the engine or out of the tailpipe. What exactly would cause that. Is it a realistic liklihood that these bits of metal can just fire out of the engine bay?

Well when offroaders are rolled and diesel engines run on an engine might well explode.   But as to a VW group TDI I doubt that.  Even with one that has oil dilution with the diesel.
