Re: reno espace 2.2 black smoke
Black smoke from the exhaust denotes either an air intake or misfueling problem so obviously there is a serious problem somewhere. Modern Dci engines should run smooth and clean.
The 2.2 Dci engine has a notorious history of failing inlet manifold gaskets and aslo cracked inlet manifolds. Could also be a stcicking
valve fault or even leaking injectors. Personally I wouldn't put much faith in a Renault service history when it comes to the 2.2 Dci engine as neither checking the inlet nor
valve is part of any service schedule.
