What Does It Mean to Smell Exhaust Inside a Diesel Vehicle?

Model: (Various brands) Various
Part: Checks and maintenance

Video tutorial

In this video, you can see the possible reasons for smelling exhaust fumes inside the cabin of your diesel car: indeed, upon raising the vehicle, we discover there is a leak of exhaust gases, with the turbocharger and EGR valve completely sooted. Unfortunately, to reach a solution, you must disassemble everything, as it is impossible to see anything clearly.

Once you get to the heart of the problem, you will see that the issue is caused by the EGR heat exchanger, so there is still much to disassemble. After painstakingly reaching the exchanger, you will find that the flap that diverts the exhaust gas flow is damaged and therefore unusable.

You need to replace all the gaskets, the pipe, and the EGR heat exchanger, which you will reassemble, and then, after cleaning them, put back all the parts you disassembled. After performing an 'olfactory' check to ensure the problem is resolved, you can consider your operation complete.
