Specialized service · Intake
In diesel engines, the mix of EGR soot with oil vapours creates a carbon paste that obstructs the entire intake system. Professional cleaning restores airflow and returns performance to the engine.
The problem
In diesel engines, cleaning the intake system is even more critical than in petrol engines. Diesel works with a higher compression ratio and uses EGR (Exhaust Gas Recirculation), which continuously reintroduces soot into the intake system.
A dirty intake system generates more soot during combustion. This excess overloads the DPF/FAP, causing frequent regenerations and eventually total filter clogging — an extremely expensive part to replace.
Failure symptoms
Consequences
Intake carbonization is progressive and never resolves itself. The deposits become harder and more difficult to remove over time.
