P2002 on SEAT
Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
P2002 on SEAT vehicles indicates diesel particulate filter efficiency below threshold (bank 1). Au7o has documented this code across 2 SEAT models — most commonly on Ibiza, Leon. P2002 indicates that the diesel particulate filter (DPF) on bank 1 is performing below its required efficiency threshold. The DPF captures and stores soot from diesel exhaust and periodically burns it off (regeneration); the engine computer monitors exhaust pressure across the filter and other data to judge how well it's trapping and clearing soot. When that efficiency falls too low, this code sets. Symptoms can include reduced power, a clogged-filter warning, frequent or failed regenerations, and increased emissions. Typical repair costs on SEAT range from $200 to $1,500, depending on the specific model and root cause.
Common Causes of P2002
- •Clogged or damaged diesel particulate filter
- •Failed or incomplete DPF regeneration (mostly short trips)
- •Faulty differential (DPF) pressure sensor or hoses
- •Faulty exhaust temperature sensor(s)
- •Exhaust leak before or across the DPF
- •Engine running issues causing excess soot (injectors, EGR, turbo)
- •Use of incorrect (non-low-ash) engine oil or fuel quality issues
P2002 on SEAT by Model
SEAT Ibiza(1 issue)
- Diesel Particulate Filter (DPF) Clogging on TDI Diesels2009-2016
The TDI diesel Ibizas (notably the 1.2 TDI/1.6 TDI Ecomotive) suffer DPF clogging, especially when used predominantly for short urban journeys that never reach regeneration temperature. Incomplete or repeated active regenerations dilute the engine oil with diesel (raising the oil level), which can in turn accelerate engine wear. Symptoms include a DPF/glow-plug warning light, limp mode, increased fuel consumption and a smell of diesel in the oil. The problem is well documented on owner forums and Q&A sites for the Ibiza ST Ecomotive.
SEAT Leon(1 issue)
- EA189 TDI Diesel: EGR/DPF Clogging and Post-Dieselgate Oil Dilution2009-2015
Diesel Leons (1.6 TDI and 2.0 TDI) using the EA189 engine - the engine at the centre of the Dieselgate emissions scandal - are widely reported for EGR valve and EGR-cooler clogging with soot and DPF (diesel particulate filter) blockages, especially on short-trip/urban driving that prevents the filter reaching regeneration temperature. After the mandated emissions 'fix', many owners additionally reported worsened DPF behaviour and oil dilution (diesel washing into the sump during frequent active regens), requiring more frequent oil changes.

What does P2002 mean on SEAT?▼
P2002 stands for "Diesel Particulate Filter Efficiency Below Threshold (Bank 1)." P2002 indicates that the diesel particulate filter (DPF) on bank 1 is performing below its required efficiency threshold. The DPF captures and stores soot from diesel exhaust and periodically burns it off (regeneration); the engine computer monitors exhaust pressure across the filter and other data to judge how well it's trapping and clearing soot. When that efficiency falls too low, this code sets. Symptoms can include reduced power, a clogged-filter warning, frequent or failed regenerations, and increased emissions. On SEAT specifically, this code is documented across 2 models.
What causes P2002 on SEAT vehicles?▼
Common causes on SEAT: Clogged or damaged diesel particulate filter, Failed or incomplete DPF regeneration (mostly short trips), Faulty differential (DPF) pressure sensor or hoses, Faulty exhaust temperature sensor(s), Exhaust leak before or across the DPF. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2002 on a SEAT?▼
