Black smoke/liquid on cold start
Hi, ive got a 190e 1.8, we call this a 180e in australia. It has 117,000 kms and runs and looks like brand new. One small issue though, during cold starts the exhaust pipe intermitently releases black smoke but this stops once the engine is warm or once the accelerator is pushed a bit. The car runs fine during this phase and idle mixture appears correct. All Filters spark plugs rotor cap leads were replaced recently plus the oxygen sensor. Pressure regulator is fine. Fuel economy is 16-20 litres/100 kms. Any suggestions or even idle comments would be appreciated.
