Porsche DPF cleaning
£275 once, or a dealer bill running into four figures for a Cayenne, Macan or Panamera filter that was probably never broken. Mobile chemical flush, we come to you, across Greater Manchester. Call 0161 694 7331.
The replacement bill on a Porsche
A new DPF from a Porsche dealer is a serious bill. On the 3.0 V6 TDI fitted across the Cayenne, Macan and Panamera, an OEM filter fitted at a dealer typically runs to £1,200 to £1,500 or more once labour and diagnostics are added; on the Cayenne S Diesel's 4.2 V8 TDI, the larger exhaust layout pushes the job higher still. Independents can often manage the aftermarket part for £800 to £1,000 fitted, but that's still a four-figure decision for a filter that, in most cases, isn't actually broken.
The honest split: a blocked Porsche filter, one simply carrying more soot than the ECU wants to see, responds to a chemical clean at £275. A physically cracked or melted filter doesn't. The two look identical from the driver's seat, which is exactly why a dealer quoting for a new filter without checking which one you've got is worth a second opinion.
Clean, repair, replace or delete
| Option | Typical cost | What it fixes | Road-legal? |
|---|---|---|---|
| Clean/repair | £275 fixed | Clears a soot blockage | 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 Porsche filter that's blocked rather than damaged, which covers most of what we see across the Cayenne, Macan and Panamera range. Replacement only becomes necessary once a filter has physically failed. Porsche's V6 and V8 TDI units share their core architecture with Audi's diesel range, so see our Audi DPF cleaning hub if you're weighing up an A6, A8, Q7 or Q8 alongside a Cayenne or Panamera.

Porsche models and engines
Cayenne (2009 onward)
957 3.0 V6 TDI, 958 3.0 V6 TDI and S Diesel 4.2 V8 TDI (2013 to 2016). The model we quote for most across the range, and the one with the widest engine spread.
Macan (2014 to 2018)
3.0 V6 TDI. A single generation, single engine on this list, which keeps the diagnostic straightforward.
Panamera (2011 to 2016)
970 Panamera Diesel 3.0 V6 TDI. Porsche's four-door saloon, sharing its V6 TDI with the Cayenne of the same era.
What happens on the day
We come to the vehicle wherever it's parked, run a diagnostic to confirm the soot load and any stored codes, then introduce the cleaning agent through the DPF's existing service ports. A controlled engine sequence works the agent through the substrate, followed by a differential pressure check to confirm flow has been restored. Codes are cleared and the warning light is off before we leave. The whole visit takes roughly 90 minutes, and the filter never comes off the car.
