DPF efficiency below threshold on Peugeot HDi — clogged DPF and Eolys fluid empty on 1.6/2.0 HDi.
Peugeot P2002 — DPF efficiency below threshold on Peugeot HDi — clogged DPF and Eolys fluid empty on 1.6/2.0 HDi. Typical UK independent garage cost: £140–£1400.
What actually causes P2002 on a Peugeot
PSA DPFs use Eolys fluid (cerium additive) injected into fuel to lower regen temperature. When the Eolys tank empties, regens stop completing and P2002 follows within months. Always check Eolys level first — top-up is £40 and clears the issue if caught early.
Peugeot engines that log P2002
- 1.6 HDi DV6 (208/308/3008)
- 2.0 HDi DW10 (308/508/5008)
How we diagnose P2002 on a Peugeot
- Check Eolys fluid level (under the tank or boot floor depending on model)
- Read DPF soot/ash and regen-distance counters
- Top up Eolys and reset counter via Lexia/Diagbox
- Forced regen if soot load below 80%
The common misdiagnosis to avoid
Garages quote DPF replacement on P2002 without checking Eolys level — a £40 top-up and forced regen often clears it.
Peugeot P2002 repair cost in the UK
Expect £140–£1400 including parts and labour at an independent garage. Main-dealer quotes on Peugeot are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.
Bob's workshop tip
PSA HDi P2002 — Eolys first, every time. Customers thank you for the £40 fix instead of a £1k DPF.

Symptoms drivers report with P2002
- The 'Engine Service Now' message on the dash, often without a limp mode initially.
- Thick black soot deposits around the inside of the tailpipe (it should be clean enough to eat off).
- A heavy smell of diesel fumes inside the cabin when sitting at traffic lights.
- The car seems to perform fine but the 'DPF Full' warning keeps popping up every 50 miles.
- Excessive cooling fan noise because the car is constantly trying (and failing) to start a regeneration.
Repairs that clear P2002
- Static regen on scan tool
- Replace pressure sensor
- Injector leak-off test
- Chemical DPF clean, replace if blocked >80%
