Volkswagen P2002

DPF efficiency below threshold on VW — substrate damage after failed regens or post-dieselgate software complications.

Volkswagen P2002 — DPF efficiency below threshold on VW — substrate damage after failed regens or post-dieselgate software complications. Typical UK independent garage cost: £220–£2400.

What actually causes P2002 on a Volkswagen

VW EA189 engines post-emissions software update see more frequent regens, which accelerates ash accumulation and substrate stress. P2002 is the 'this DPF is done' code — usually replacement or professional clean. EA288 (later EU6 engines) generally last better but still fail on short-trip cars.

Volkswagen engines that log P2002

• 2.0 TDI CR EA189 (Golf, Passat, Tiguan)
• 2.0 TDI CR EA288 (Golf Mk7, Passat B8)
• 1.6 TDI CR (Polo, Audi A1)

How we diagnose P2002 on a Volkswagen

1. VCDS: read DPF soot, ash, regen count, last regen distance and time
2. Inspect DPF substrate via endoscope where access permits
3. Back-pressure test cold and hot
4. Check VIN against VW recall/goodwill database
5. Quote off-vehicle clean (£250) before full replacement (£1,500+)

The common misdiagnosis to avoid

Don't replace a DPF before checking for active recalls or extended warranty on EA189 post-emissions cars — some customers are still being offered free DPF work under goodwill.

Volkswagen P2002 repair cost in the UK

Expect £220–£2400 including parts and labour at an independent garage. Main-dealer quotes on Volkswagen 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.

Service campaign / TSB note

VW post-emissions software (23R7/23X6) altered DPF regen strategy on EA189.

Bob's workshop tip

After any DPF work on a TDI used for short trips, recommend a 30-mile motorway run weekly — this single habit doubles DPF lifespan.

Codes usually seen alongside P2002 on Volkswagen

• P244A
• P244B
• P2463

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%
