Question

I've noticed some black smoke coming from my exhaust occasionally. I'm worried this could be dangerous, so what could be causing this?


Answer

Depending on what type of engine is fitted (petrol/diesel), diesel engines do produce black smoke when accelerating especially when the vehicle has been driven on short start stop journeys. Petrol engines should not produce black smoke, if this is the case diagnostic tests should be carried out for rectification.
