Eolys Fluid Re-Filling — Mobile Service by Carbon Clean Co
Keep Your Diesel Healthy, Efficient & Emission-Compliant
Eolys (sometimes called PAT or DPF additive) is a cerium-based catalyst that’s dosed into the fuel tank of many modern diesels from Peugeot, Citroën, Ford, Volvo and others. It lowers the temperature at which soot burns, allowing the diesel-particulate filter (DPF) to regenerate cleanly during normal.
When the additive reservoir runs low the ECU triggers a warning light (see image above). Ignore it for long enough and the car will limp, fuel economy will dive, and costly filter or turbo damage can follow in as little as 1,000 miles.frenchcarforum.co.uk Typical tanks last 70–120 k miles, so most owners face at least one top-up in the vehicle’s life.

Our 6-Step Re-Fill & Reset Procedure
- Confirm the Fault
Scan the ECU for DPF-additive codes and check remaining fluid level. - Pressure-Test the System
We run a low-pressure leak test on the additive circuit; hidden pipe cracks are a common cause of repeat warnings and fuel odours. - Drain or Prime
Some models need the old pouch removed; others allow a direct top-up. We handle both with purpose-built refill rigs to avoid spills. - Dose with the Correct Fluid
We carry Eolys 176, PowerFlex, Infineum F7995 & F7680 to match OEM specs. - ECU Counter Reset
Using dealer-level software we tell the additive ECU the tank is full, clearing the dashboard light immediately. - Regeneration Check-Run
A short, controlled road test confirms that the DPF reaches regeneration temperature and that no new faults are logged.
Problems a Simple Leak or Low-Additive Level Can Cause
- Premature DPF blockage and expensive forced regeneration
- Reduced power / limp-mode on hills or motorways
- Poor fuel economy caused by constant post-injection
- Surging or rough idling from skewed exhaust back-pressure
- MOT emission failures and potential fines in low-emission zones
Our pressure-test during the refill pinpoints even hair-line leaks, eliminating repeat visits.

If your diesel has an under-floor additive tank or refill pouch, we can service it.
FAQ
How long does the refill take?
Around 60 minutes on most models, including diagnostic reset.
Will ordinary DPF cleaners work instead?
No. Tank-based cleaners sit in the fuel for minutes; Eolys is dosed every fill-up for thousands of miles.
Is it safe for the environment?
Yes. We recover any residual fluid and follow hazardous-waste regulations; the refilled system reduces soot burn-off temperature, cutting particulate emissions overall.
Do you guarantee the service?
Every refill comes with a 12-month / 12,000-mile workmanship guarantee plus the additive manufacturer’s warranty.
