The EGR valve is exposed to exhaust gases that generally contain oil particles and unburnt diesel, which tend to clog the valve: therefore, a simple cleaning can restore its function. It is also advisable to clean the manifold to which the valve is connected, as combustion residues can also clog the manifold itself.

For the vehicle in question, dismantling the valve is very straightforward: it is located at the front of the engine, and you only need to remove the plastic cover to access the fastening pins. Additionally, the manifold has a sort of cap, making dismantling and cleaning very easy to perform.

Once the manifold cap and the EGR valve are removed, use brake cleaner to carry out the cleaning.
