How to Prepare a DPF Service for Euro 7 — Technology Ready for Stricter Standards
At a glance — what actually changes
• Dates: M1/N1: new types 29 Nov 2026, all new 29 Nov 2027. M2/M3/N2/N3: new types 29 May 2028, all new 29 May 2029. (EUR-Lex)
• Light-duty (M1/N1): tailpipe pollutant limits remain at Euro 6 values, but PN10 applies, RDE is expanded, and new rules cover brake particle and tyre abrasion emissions.
• Heavy-duty (M2/M3/N2/N3): tighter limits (e.g., lower NOx/PM, PN down to 10 nm) plus new NH₃ and N₂O caps and harmonised cycles.
• Durability: in-use compliance extended up to 200,000 km or 10 years (light-duty), with stronger on-road verification.
• Compliance tools: Environmental Vehicle Passport (EVP) and on-board OBM/OBFCM data increase transparency of real-world performance.
What Euro 7 changes (and why workshops should care)
Euro 7 re-frames compliance from a one-off lab test to long-term, real-world performance. For light-duty vehicles (M1/N1), pollutant limit values stay at Euro 6 levels, but regulators now count particles ≥10 nm (PN10), expand RDE coverage, and add brake and tyre emission requirements. Heavy-duty categories (M2/M3/N2/N3) face materially stricter limits (NOx/PM) and new species (NH₃/N₂O), with harmonised WHSC/WHTC limits and strengthened on-road checks.
Critically, Euro 7 extends emissions durability—think 200,000 km / 10 years for light-duty—so post-service filter performance matters more than ever. If cleaning leaves residue that raises Δp, the vehicle’s real-world emissions buffer shrinks.
Dates you must communicate to customers:
• M1/N1: new types from 29 Nov 2026, all new registrations from 29 Nov 2027.
• M2/M3/N2/N3: new types from 29 May 2028, all new registrations from 29 May 2029. (EUR-Lex)
The practical risk: residue after drying
Basic “wash + passive dry” processes often leave fine PM that settles as water evaporates. These residues inflate backpressure (Δp), undermine airflow and shorten the time a vehicle remains compliant under Euro 7’s longer durability horizon. This is a process problem—not a customer problem—and it’s fixable by upgrading the method, not abandoning hydrodynamics.
The Hybrid Advantage — a three-stage process that prevents residues
Otomatic’s DPF-Hybrid™ enhances classic hydrodynamic cleaning with two additional steps that tackle exactly where Euro 7 raises the bar: residue control and repeatability.
1. Pneumatic pre-cleaning — high-energy air pulses open blocked channels and dislodge dry deposits so rinse water can reach deeper.
2. Hydrodynamic flushing — directed flow with detergent removes soot/ash thoroughly.
3. Impulse drying — hot pulsed air physically expels moisture and suspended particles before they can dry and re-deposit.
4. This sequence mitigates post-drying residue and protects the ceramic monolith—key to stable Δp over a longer in-use period.

AI automation for consistency (and auditability)
AI SmartClean™ adjusts direction, pressure, flow and cycle length to the filter’s size/structure/contamination—reducing operator variability and damage risk. For Euro 7, that consistency is gold: it supports repeatable outcomes and clean before/after evidence when customers or authorities ask for documentation.

Your Euro 7-ready DPF service — a 6-point checklist
1. Measure & document every job: Δp (backpressure), airflow, and (if applicable) mass of removed deposits — before/after, with a PDF report handed to the customer.
2. Standardise the cycle: pre-clean → wet flush → impulse-dry. Avoid “wash + passive dry” on modern filters.
3. Calibrate for repeatability: use AI SmartClean™ profiles to cut operator error; log parameters for traceability.
4. Protect the monolith: verify pressures/temperatures by substrate type; prefer processes proven to avoid post-drying deposits.
5. Waste handling: use dedicated chemistry and filtration; follow proper chemical and filter cartridge disposal rules (add HowTo on your site).
6. Train your team: week-over-week review of results, parameter logs, and complaint-free rate.
Korduma kippuvad küsimused
Q1: Do light-duty Euro 7 vehicles have stricter pollutant limit values than Euro 6?
A: The limit values for tailpipe pollutants in M1/N1 remain at Euro 6 levels, but Euro 7 adds PN10, broadens RDE, and introduces brake/tyre emission rules—so the practical bar for compliance is higher.
Q2: When will Euro 7 actually start to matter for my workshop?
A: From 29 Nov 2026/29 Nov 2027 (cars/vans) and 29 May 2028/29 May 2029 (trucks/buses). Vehicles hitting your bay will increasingly be Euro 7-approved and more sensitive to poor cleaning. (EUR-Lex)
Q3: How does Euro 7 track real-world performance?
A: Via expanded on-road testing and data transparency—the Environmental Vehicle Passport (EVP) and OBM/OBFCM make emissions-relevant information available to users and authorities. Poor cleaning tends to show up in the data.
