Hyundai i30 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 an i30
A new DPF for an i30 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 factoring in the time the car spends off the road while parts are ordered in.
What most garages don't lead with is that the majority of blocked i30 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 an i30 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.
i30 engines covered
1.4 CRDi, 2007 onward
The smaller of the two diesel options across the i30's production run. Cheaper to replace at a dealer than the 1.6, but no less prone to a soot blockage on short, low-load journeys.
1.6 CRDi, U2 family, 2007 onward
Fitted more widely across the range and shared with several other Hyundai and Kia models. A newer replacement part than the smaller unit, but still a four-figure job at a dealer if the filter has genuinely failed, which is rare compared with a simple blockage.
Both engines share the same U2-family regen strategy and store the same fault codes once a blockage sets in, so the diagnostic process is identical whichever one is fitted to your car. Both are covered by the same £275 fixed clean, whichever you have. See our full Hyundai range we cover.
What happens on the day
We arrive at your home, workplace or wherever the i30 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.
