Black smoke from tailpipe, will not come close to passing emissions test. Turbo has been replaced. The model is 97 850 turbo wagon. Does this mean the transmission in going. I just bought this car two days ago? Yikes.

loads of black smoke, loss of power and heating all indicate a faulty turbo--not winding up to provide the air flow required
check turbo actuator got the turbine vanes
Take it to a turbo repair shop and have it tested.
this case , you have to check turbo charger , when high RPM white smoke means lubricate oil goes to engine so give white smoke . on low rpm trubo close coming black smoke means no enough air gose to engine so this need to replace turbo . some type of turbo can be clean the wase gate ( which open with diafam beside turbo) make sure it's moving when accilerate. check vacum is ok . then clean wase gate > only some type have wings inside )if no replace turbo
Black smoke indicates you are running rich. You may have to address the fuel injectors to make sure one is not stuck open. After replacing the MAF censor this would be my next step. Also your turbo seal might be leaking causing your truck to run rich throwing off the o2 censor. Also you can get black smoke from turbo blowby. Not burning oil but actual oil passing the rear turbine seal and getting into the exhaust. This should give you a few good places to check out. Good luck to you.
The turbo will not cause black smoke. White smoke, yes, if its passing oil into the engine, but not black.
First check that the air intake and filter is not blocked, check that the air hoses from the turbo and intercooler are not collapsing when given throttle.if thats ok, then get the injectors tested, if they are ok then you need to get the injection pump serviced. Black smoke is a result of overfuelling, either by the poor dispersal of fuel from the injectors or the pump, or blockage of air into the engine on the intake system.
Hope that helps
I wouldn't drive it until you get a scan done to determine what the problem. Diesels are very expensive to fix. I would lean towards the cam shaft sensor has failed but don't quote me on that.
oil leaking into the turbo....there are places that rebuild turbos. Check the yellow pages or online. I had to replace the turbos on my Porche and promised to never buy a turbo anything again.
