[What Is DPF Cleaning? | What Is DPF Cleaning?]
DPF cleaning is the process of removing accumulated soot and ash from your vehicle’s diesel particulate filter to restore proper exhaust flow, reduce back-pressure, and ensure emissions compliance. Through advanced techniques—like ultrasonic extraction, controlled thermal regeneration, and precision solvent flushing—we break down and flush away trapped particulates. The result is improved engine efficiency, smoother throttle response, better fuel economy, and peace of mind that your Euro 6 filter is operating at peak performance.
[Get It Right The First Time Around? | Don't Trust The CowBoys]
Don’t let cowboy “cleaners” butcher your DPF with slap-dash fixes—our authorised MOT-station team removes your filter, ultrasonically restores near-100% porosity, re-welds it, and flow-tests every unit. You’ll get a 100% MOT-safe certificate of cleanliness, exhaust engraving, and full registration tracking—so you’re far less likely to fail the new emissions test than with any amateur job. Trust the experts who know the MOT standards inside out.
How It Works?
Step 1
Book Appointment
Select your appointment date, time, and location—either at our workshop or via our mobile tuning service—according to the service you choose. Once booked, you'll receive a confirmation email with appointment details, technician info, and preparation tips, plus a friendly reminder before your slot to ensure a seamless experience.
Step 2
On-Site DPF Service
Our specialist arrives on-site with advanced equipment to assess soot load and back-pressure, then uses ultrasonic extraction, thermal regeneration and a solvent flush—finishing with flow and pressure tests to restore your DPF in about 90 minutes.
Step 3
Data Report
You’ll get a concise service report with back-pressure graphs, soot-reduction stats, live sensor and flow data, and Euro 6 emissions readings—plus we’ll reset your ECU’s DPF settings and share maintenance tips.
DPF Cleaning Service
At Precision Remaps UK, we deliver comprehensive DPF cleaning solutions to restore your vehicle’s exhaust efficiency and emissions compliance, including:
