Hi,
I have a 2000 Golf MK4 GT TDi which at the weekend appeared to blow the turbo. As I pulled up the slip road onto the motorway, there was a bang, lots of black/brown smoke out of the exhaust, a very loud turbo whistle, no (turbo) power, and a noise similar to a blowing exhaust. As I limped down the motorway, if I tried to accelerate, there would be more black smoke and juddering whilst it tried to apply a bit of power. When I pulled over, the idle was not stable and oil was leaking onto the floor below the driver side headlight.
The car turns over and starts ok, but with the same blowing and whistling noise coming from behind/below (ish) the driver side headlight, not that I know what I'm looking for!
I was recovered by the RAC and left the car at the garage, who have said the turbo has blown and it will be about £1000-1150 to supply and fit a new turbo, providing it hasn't done any further damage. One other garage has quoted £850 which seems too cheap.
After reading a few other posts, it seems like it might not be the turbo that has gone, as this would have caused maybe white or blue smoke?
Any advice would be most appreciated!
