Modern diesel engines are equipped with Diesel Particulate Filters (DPF) and Exhaust Gas Recirculation (EGR) systems that can easily become clogged, especially if you mainly do short trips around Norwich or King’s Lynn. ALT Mobile Mechanic specializes in mobile DPF cleaning and emissions diagnostics across Norfolk. We help you avoid the massive cost of a full DPF replacement by using professional cleaning agents and “forced regeneration” techniques right at your location.

Emissions faults often trigger a “Limp Mode” that leaves your car with no power. Our 15 years of experience allows us to diagnose whether the issue is a blocked filter, a faulty sensor, or a stuck EGR valve. Serving towns like Thetford and Cromer, we provide a high-tech solution that cleans your system and restores your engine’s performance and fuel economy, ensuring you pass your next emissions test with ease.

We are committed to honest, cost-effective repairs. Instead of recommending an expensive new part, we focus on restoring your existing system whenever possible. Our mobile service in Dereham and Fakenham is designed to save you hundreds of pounds while keeping your vehicle environmentally friendly and running at peak efficiency.
