Why my ml 270 cdi is blowing out smoke and loses power?

Your ML 270 CDI may be blowing smoke and losing power due to several potential issues. Common causes include a clogged air filter, faulty injectors, or a malfunctioning turbocharger, which can affect engine performance and lead to smoke from the exhaust. Additionally, worn piston rings or valve seals may cause oil to enter the combustion chamber, producing blue smoke. It's advisable to have the vehicle inspected by a qualified mechanic to diagnose and address the underlying issue.
