Question about BMW 525
Black smoke srart great when cold then goes funny at running tempature changed fuel pump main one in engine still doing same this is a 525tds m reg 1994
Mixture control black smoke is rich mixture ,but sorry not sure what or where the control is weither its a sensor or a ECU fault. most likely cause is the autochoke staying can only sugest the main agent or a decent garage who have some test equipment .if you see any sensors in or around the top of the engine try disconnecting them one at a time and see what happens if it stops,and engine will not start when its cold then you have found the problem .
