Peugeot P2002

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

1. Check Eolys fluid level (under the tank or boot floor depending on model)
2. Read DPF soot/ash and regen-distance counters
3. Top up Eolys and reset counter via Lexia/Diagbox
4. 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.

Codes usually seen alongside P2002 on Peugeot

• P2463
• P1471

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

• Read soot and ash loading on live data before spending anything
• Clean or replace the DPF pressure pipes and sensor
• Forced regeneration if soot loading is high but ash is low
• Off-car DPF clean, or replacement if the substrate is damaged

Reading P2002 on a Peugeot properly

A generic reader will show P2002 and nothing else. What matters is the freeze-frame data stored with it — engine speed, load, coolant temperature and fuel trims at the moment the fault was logged — plus whether any other module on the Peugeot has logged something at the same time. Codes rarely arrive alone, and the order they were stored in usually points at which one is the cause and which are the consequences.

Clearing P2002 without fixing it

Erasing the code resets the Peugeot's readiness monitors as well as the light. The fault returns on the next drive cycle if the cause is still there, and in the meantime the incomplete monitors can stop the car passing an emissions check. After a genuine repair, the car is driven until the relevant monitor completes before it is handed back.

Bob's Mechanical Repairs is an independent garage in Birnam, Dunkeld, Perthshire, with 32 years of Bob's experience on the tools. If P2002 is showing on your Peugeot, bring any scan results with you — we will read the live data ourselves, confirm which cause it actually is, and price the repair before any work starts.
