0 to 60 in 3-5 minutes

K03 TURBO CHARGERMy Jetta TDI (Turbocharged Direct Injection) is having issues, in that the turbo, created by a turbocharger (pictured at right), is no longer working. The turbocharger takes compressed air and a lot of gas and, like the name says, injects a turbo boost into the engine, giving my TDI a nice little boost from about 2,500 RPM to 4,000. However, without this nice little boost, while I can still drive fast, I cannot accelerate much at all. It literally takes up to 5 minutes, depending on the slope of the road, to get to 60 MPH.

This may sound all bad, but it’s not. I’ve been getting awesome gas mileage, about 45 MPG, which is much higher than the typical 35-40 MPG. Also, as someone who usually drives pretty fast, I’ve learned a lot about humility and patience.

However, this past week I put on about 1,000 miles between a trip to Chicago and 3 days in Indy. If you were one of those people who was extremely annoyed by the slowly accelerating white Jetta on the highways between Chicago, Indy and Goshen, I apologize, especially to the trucker who flipped me off and tried to run me off the road. I really was accelerating as fast as I could and was not trying to ruin your day.

My mechanic, Eckhert, a somewhat crusty old German man, will be tending to the TDI this week. If my working theory that it’s just a cracked air tube is correct, it’ll just be a $25 or so fix.

  • Update on the car: It was a cracked air tube that's out of sight behind the turbo. Eckhart was stumped, as he'd checked everything he could think of, but then, while sitting on the john, he told me, he was reading in some sort of mechanic's magazine about TDIs and problems they have and thought to check that air tube. An $84 fix, including an oil change and steering fluid top-off. I can accelerate again!

    The intake manifold could be clogged up, especially just past the EGR valve. Did the check engine light come on, when it failed? The CVT or waste-gate type mechanism could be frozen because of soot build-up, (the airplane wing like fins change the angle of the air hitting the impeller and controls boost) but if you drive fast that shouldn't be the problem, unless the car was babied before you bought it.
