Here at DPF Ultra Clean we understand DPF & SCR Exhaust systems, and what causes them to go wrong better than possibly any other cleaning facility in the UK. We have been successfully Diagnosing and Repairing Engine management system faults on Diesel vehicles for over 20 years. This now vast and rich knowledge base we have amassed is quite phenomenal, allowing us to offer guidance on what might potentially be causing your exhaust filter to block, how best to identify faulty components and prevent further premature blockages. We also have very extensive diagnostic equipment covering all makes of vehicles, Cars, Vans, Light Commercial Vehicles and Heavy Goods Vehicles up to and including Euro 6.
