Hyundai Tucson DPF cleaning
£275 once. Or a garage bill running into four figures for a new filter you probably don't need. Mobile chemical flush, we come to you.
The replacement bill on a Tucson
A new DPF for a Tucson isn't a small purchase. An aftermarket filter fitted independently typically runs to £800 to £1,000, while an OEM part fitted at a dealer can reach £1,200 to £1,500 or more once labour is added. That's before the car sits off the road while the part is ordered in.
What most dealers don't lead with is that the majority of blocked Tucson filters are dirty rather than damaged. A chemical clean restores flow through a soot-loaded filter for a fraction of the replacement cost, and the filter itself never has to come off the car.
Clean, repair, replace or delete
| Option | Typical cost | What it fixes | Road-legal? |
|---|---|---|---|
| Clean/repair | £275 fixed | Clears a soot blockage restricting exhaust flow | Yes |
| Replacement | £800 to £1,500+ fitted | Needed only if the filter is physically cracked or melted | Yes |
| Delete | Call to discuss | Removes the DPF from the software permanently | No |
Cleaning is the right first call for a Tucson whose filter is blocked rather than damaged, and that covers most of the faults we see. Replacement only becomes necessary once a filter has physically failed and no longer holds together well enough to clean. It doesn't suit a road car carrying a routine fault code, which a clean resolves instead. Repair is simply the search term some owners use; the job itself is the same £275 chemical flush, priced and carried out identically to a clean. See our full replacement cost comparison for more detail.
Tucson engines covered
1.6 CRDi
The smallest diesel offered on the Tucson range, fitted mainly to lower-power trims. Cheapest to replace at a dealer of the three engines, but no less prone to a soot blockage on short journeys.
1.7 CRDi
A common mid-range fitment on earlier cars. Shares its regen behaviour with the equivalent engine across the Hyundai and Kia range.
2.0 CRDi
The larger unit, fitted across both generations covered here (2015 onward). Best placed of the three to shift soot on a longer run, but still not immune on a mostly urban Tucson.
None of the three engines uses an additive fluid, so a blocked filter clears through driving conditions and a proper clean rather than a fluid top-up. All three respond to the same £275 fixed clean. See our full Hyundai range we cover.
What happens on the day
We arrive at your home, workplace or wherever the Tucson is parked, run a diagnostic to confirm the soot load and stored codes, then introduce the cleaning agent through the DPF's existing service ports. A controlled engine sequence works the agent through the filter, we check the result with a post-clean pressure test, then clear the codes. Roughly 90 minutes from start to finish.
