My 2002 mk4 tdi golf is throwing out alot of black smoke at times, usually when driven low in a gear. Also when you drive along, it will lose power, usually when its warmed up and not when its cold? my mechanic took off all the air pipes and cleaned out the turbo unblocked the breather pipe and put back together, there was some oil found in these pipes. When put on his computer it came up with an air in system error. Have also changed the mas flow meter but still no better, please,please, please can anyone help. When running ok she goes well.
