Engine running to red line and unable to "kill" by turning off key

(1996 Volkswagen Passat TDI)
in Eaton Rapids, MI on October 25, 2010
driving car 60 mph and it redlined. Tried to shut off by turning off key and it kept running. Friend (mechanic), says he found the "turbo" behind motor and in front of firewall seized up and it was running on oil? Help with diagnosing would be appreciated. Only has 140,000 miles on it

Sounds like the engine "ran on oil" when the turbo failed, was the engine low in oil or did you see a cloud of smoke out the exhaust? I haven't heard of turbo failure on your engine perhaps check on line VW or VW turbo diesel forums on line. There is a professional service called Identafix.

oil was not "low" but down. Mechanic tells me intake is full, air filter is full, basically oil in places it shouldn't be. When engine red lined, yes, big cloud, oily cloud? couldn't say, although when it happened I pulled over to side ot road and people stopped thinking car was on fire. I finally got motor to stop by putting in 4th gear and "lugging" it down.

you had a "runaway diesel". Diesel mechanics know what this is. Happened to me on an isuzu diesel years ago. Scary, apparently a vacuum develops that sucks diesel fuel into the cylinders - and won't stop even when ignition turned off.
