Audi A5 DPF cleaning
2.0 and 3.0 TDI, EA189 through to EA897. Mobile chemical flush through the DPF's existing service ports, £275. Whichever engine your A5 carries, we come to you rather than the other way round. Call 0161 694 7331.
Which engine is in your A5
Two generations of A5, and a handful of diesel engines across them, each behaving slightly differently once the filter starts to load.
| Engine | A5 generation | Years | DPF/regen note |
|---|---|---|---|
| 2.0 and 3.0 TDI EA189 | B8 | 2007 to 2016 | Common-rail injection, no additive fluid, short-run urban blocking is the usual pattern |
| 2.0 TDI EA288 | B9 | 2016 onward | No additive; twin-stage regen strategy on some Euro 6 applications |
| 3.0 TDI EA897 | B9 | 2016 onward | Larger unit, higher exhaust temperature under load, less prone to blocking on mixed driving |
The B8's EA189 units are the ones most likely to arrive with a fault after a run of short trips, a pattern owners across the Volkswagen Group range will recognise. The B9's EA288 and EA897 catch it slightly earlier in most cases, but neither is immune on a car used mainly for short commuter runs into Manchester or Salford.
How the clean is done on an A5
The process is the same across every engine in the range, carried out wherever the car is parked rather than at a garage.
A diagnostic read confirms the soot load and pulls any stored fault codes before work starts.
The chemical cleaning agent is introduced through the DPF's existing service ports, no removal, no ramp.
A controlled engine sequence works the agent through the filter substrate, typically 60 to 90 minutes on site.
A post-clean differential pressure check confirms exhaust flow has been restored across the filter.
Stored fault codes are cleared and the warning light goes out before we leave.
Which of these does your A5 need
Most A5 DPF warnings are a soot problem, and our clean and DPF repair are the same £275 fixed service under either name. Replacement only becomes the right call once a filter has physically cracked or melted, something a diagnostic confirms rather than assumes; see DPF cleaning vs replacement for the full cost picture.
Does the regen system differ between A5 engines?
Yes, to a degree. The EA189 relies purely on exhaust temperature and drive cycle timing developed for an earlier generation of emissions control, while the EA288 fitted from the B9 onward runs a more refined strategy that, on some applications, uses a twin-stage regen. The 3.0 TDI EA897's larger displacement gives it more thermal headroom, so it tends to warn later than the four-cylinder units on the same driving pattern. None of this changes the fix: whichever engine, a blocked filter responds to the same chemical clean.

A5 engine questions
Which engine is in my A5, and does that change the price?
Is the additive fluid (sometimes called Eolys) relevant to my A5's DPF?
Does the clean affect the turbo or the EGR system on an A5?
Can you tell from the fault codes alone which engine my A5 has?
Is a DPF delete legal on a road-going vehicle?
