DPF filter - Maintenance, repair or removal
The DPF (diesel particulate filter) is an essential component of a modern diesel engine, which reduces harmful emissions by trapping soot before it enters the atmosphere. Over time, the DPF filter can become clogged, lose efficiency or become completely blocked, which results in poor engine performance, increased fuel consumption, reduced power and the exhaust system can be completely blocked. Timely maintenance, repair or proper replacement of the DPF filter helps to avoid expensive engine damage and ensures that the car meets technical and environmental requirements. In our service, we perform professional diagnostics, cleaning, repair, replacement or - at the customer's request and in accordance with the legislation - also removal.
