If your diesel has lost its pull and doesn't respond like it used to, a clogged DPF or carbonised EGR valve are usually to blame — and they often affect each other. At RedHat Garage in Sugiez we diagnose the root cause (not just clear codes) and fix the problem for good — cleaning, regeneration or replacement depending on condition. The difference is immediately noticeable after the repair.

This is a typical symptom of the engine's limp mode, often triggered by a clogged diesel particulate filter (DPF) or an issue with the EGR valve. The control unit reduces power to prevent major damage to the engine or exhaust system. A precise diagnosis at our workshop is necessary to identify and fix the root cause rather than just addressing the symptoms.
Yes, a clogged diesel particulate filter (DPF) is one of the most common causes of power loss in modern diesel vehicles. When the filter can no longer perform its regeneration cycles correctly, the exhaust backpressure increases, and the engine enters limp mode. This is often related to a carbonised EGR valve. We diagnose the exact cause to provide a lasting solution to the problem.
The cost of resolving a DPF or EGR issue depends heavily on the vehicle model and the condition of the components. Following a thorough diagnosis, we will provide you with a detailed and binding cost estimate. You can then decide whether the work should be carried out. We do not begin any repairs until you have reviewed and approved our written offer.
To schedule an appointment, please send us a message via WhatsApp or use the 'Request an Appointment' form on our website. Please attach a photo of your vehicle registration document and briefly describe the symptoms along with the current mileage. We will then get back to you with a proposed appointment, usually within a few working days.
No, simply clearing error codes does not fix the underlying problem and usually results in the fault reappearing quickly. We focus on diagnosing the actual cause of the power loss, whether it's the DPF, the EGR valve, or another component. Only when the root issue has been resolved will the fault memory remain clear permanently.
Not necessarily. Whether a particulate filter needs replacement depends on its condition and the vehicle model. In many cases, a professional cleaning or an initiated regeneration is sufficient to restore its full functionality. We assess this during the diagnosis and propose the most technically and economically sensible solution, which will be detailed in the cost estimate.
