Hi

 

My 2001 mk2 galaxy 1.9 turbo diesel started to blow black smoke and make a funny hissing and a metal grating noise like something spinning and also looses power when under pressure which results in very heavy black smoke coming out. has anyone got any idea what this could be.

 

Ps it only makes the grinding noise when accelerating, if you ease of the throttle the noise stops but also gets faster when accelerating

Sounds like your turbo is goosed. I wouldn't drive it too hard or for too long as it could ruin your engine.

I agree sounds like a turbo problem with the symptoms you describe other reasons for black smoke could be as follows:

 

Black Smoke

Black smoke emitting from your exhaust is due to a air to fuel ratio imbalance. This occurs when the diesel fuel system is delivering either too much fuel into the engine or there is not enough air.

Below are some ideas of what is causing your vehicle to emit black smoke:-

* Faulty Diesel Injectors

* Dirty Air Filter

* Faulty Diesel Pump

* Valves clogged within cylinder head due to EGR being faulty.

* Intercooler or Turbo Charger faulty

It sounds like your turbo to me too. I would stop driving it, if at all possible, until you check it out. Your description of the noises, particularly the variation with throttle position and acceleration, is what I would expect if the vanes were rubbing on the housing (though I've never listened to a damaged one myself). If it is this and you continue to use it you can potentially get small fragments of metal debris into the engine and cause more damage. It probably needs to have the undertray removed and the turbo pipework removed so the turbo can be examined.

 

Hope it's not this but the sooner you check the better.

Thanks for the help, I checked the turbo today and the main pipe had come apart, their is a steel pipe that goes into a rubber hose and the clip had slipped off, and the steel pipe came out off the hose, i put them back together replaced the clip and all is back to normal, full power no noise and no smoke, happy days.

 

Thanks again for your replies
