Loss of power up hills.Almost as if the turbo boost not working.Had it at merc garage ,who say it is ok.Initially pulled up hill about 60mph.Offered more throttle and a big black puff came out the back.The engine had no go in it.Back on the flat and the van will not pull more than 60mph.Doesn't won't to rev more than 2,000,in any gear.
Help!
