P2002 on Skoda
Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
P2002 on Skoda vehicles indicates diesel particulate filter efficiency below threshold (bank 1). Au7o has documented this code across 2 Skoda models — most commonly on Kodiaq, Superb. 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 Skoda range from $250 to $2,500, 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 Skoda by Model
Skoda Kodiaq(1 issue)
- DPF Clogging and AdBlue/SCR System Faults on 2.0 TDI Diesels2017-2023
Diesel Kodiaqs used mainly for short urban trips frequently suffer incomplete diesel particulate filter (DPF) regeneration, leading to a clogged filter and recurring warning lights. The associated SCR/AdBlue system (urea pump, injector, NOx sensors) is complex, and a single failed component triggers an emissions fault, sometimes with a no-restart countdown warning. Symptoms include power loss, black smoke, strong exhaust smell and a check-engine light.
Skoda Superb(1 issue)
- 2.0 TDI EGR System and DPF Failure2008-2020
Same EGR cooler and DPF cluster as Octavia 2.0 TDI but more severely felt in Superb due to its motorway-heavy duty cycle. Post-Dieselgate emissions update accelerated DPF clogging in some cases. Failed EGR cooler can dump coolant into intake.

What does P2002 mean on Skoda?▼
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 Skoda specifically, this code is documented across 2 models.
What causes P2002 on Skoda vehicles?▼
Common causes on Skoda: 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.
