BMW 120d Catalytic Converter Problems

BMW 120d catalytic converter problems can amplify the exhaust emissions and a decline in engine performance. Most problems shoot from sudden temperature changes. Extreme unburnt petrol in the exhaust can convert the catalyst into a bomb shell due to extremely high temperatures and damage the catalyst substances. As a result, the catalytic converter does not work properly and requires a replacement.
