If your diesel car has started losing power, using more fuel, or flashing that DPF warning light, you’re not alone. It’s one of the most common issues we see at our workshop — and the good news is, in most cases, it’s fixable with the right DPF cleaning and diagnostics.

We help drivers from Luton, Harpenden, Watford, Hitchin, and nearby towns get their diesel cars running smoothly again. Over the years, we’ve cleaned dozens of blocked DPFs with a 100% success rate — when the filter is physically intact.

And for complete peace of mind, we offer a “No Clean – No Pay” warranty:
if the DPF can’t be successfully cleaned, you don’t pay.

We Don’t Just Clean – We Diagnose the Root Cause

A blocked DPF is often a symptom, not the actual problem. That’s why we always start with a full diagnostic check before doing any cleaning.

Many customers have come to us asking for a DPF clean, but after checking the system properly, we’ve found other faults — things like faulty sensors, leaking injectors, or exhaust temperature issues that caused the DPF to block in the first place.

Fixing the root cause first prevents the same problem coming back and saves you paying for unnecessary cleaning.

We’re honest about what we find, and we’ll always show you the readings, explain what’s happening, and give you clear options before doing anything.

Real Examples from Our Workshop

We’ve seen it all over the years:

• A Land Rover came in recently with the DPF light on. The customer had been told elsewhere it just needed cleaning, but during our checks, we found the DPF was physically damaged inside. Cleaning wouldn’t have helped, and we proved it with pressure readings. We advised a proper replacement — and saved the customer from wasting money.
• On several modern Volvo diesel models, the DPF and AdBlue catalytic converter are built into one unit. When this fails, cleaning won’t solve it, and replacing the full assembly is the only long-term fix.
• We’ve also seen cars where customers tried “DPF cleaning additives” from shops — unfortunately, these rarely help and sometimes make things worse.

Our goal is simple: be transparent, do the job properly, and only charge for what actually works.

Our Professional DPF Cleaning Process

When cleaning is the right option, we use a controlled, professional process that safely removes soot and ash without damaging the filter.

1. Diagnostic Scan & Pressure Test – we measure how blocked the DPF is and check for related faults.
2. DPF Cleaning – we use specialist equipment and cleaning solutions to break down the soot buildup and restore proper flow.
3. Post-Clean Verification – we recheck the pressures and road test the vehicle to confirm full restoration.

In nearly all successful cases, customers notice an instant improvement in performance, fuel economy, and throttle response — and the warning light disappears.
