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 5 Skoda models — most commonly on Fabia, Kodiaq, Octavia. 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 Fabia(1 issue)
- 1.6 TDI (EA189) Dieselgate Recall and Post-Fix EGR/DPF Failures2010-2015
Fabia Mk2 1.6 TDI (and some 1.2 TDI) diesels use the EA189 common-rail engine caught in the VW Group emissions scandal; UK cars were recalled from 2016 for an NOx software 'fix'. Honest John confirms the Fabia 1.6 TDI EA189 (built c.2010-2015) was among affected cars. A widely reported side-effect is that, after the emissions update, EGR valves and DPFs clog or fail prematurely - owners report warning lights, limp mode, loss of power and poor economy, with VW Group later refunding/repairing many EGR failures. Short-trip urban use makes DPF regeneration problems worse.
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 Octavia(1 issue)
- 2.0 TDI (EA189) EGR cooler cracking and DPF blockage2010-2020
On 2.0 TDI (and 1.6 TDI) diesel Octavias, the EGR cooler can crack internally, leaking coolant into the intake and causing white smoke, coolant loss and, in the worst case, hydrolock; the problem is aggravated by the post-Dieselgate emissions update raising EGR usage. Separately, the diesel particulate filter (DPF) becomes blocked on cars used mainly for short urban journeys that prevent regeneration, lighting the DPF/EML warning and forcing limp mode. Both are well-documented on Briskoda.
Skoda Scala(1 issue)
- 1.6 TDI DPF clogging and oil dilution on short-journey use2019-2020
Scala diesels (1.6 TDI, EA288) used mainly for short urban trips suffer DPF (diesel particulate filter) clogging because the exhaust rarely reaches the ~600 C needed for regeneration, so soot accumulates. Incomplete/interrupted regenerations also cause engine-oil dilution (diesel injected for regen washes into the sump), which can raise oil level and degrade lubrication. This is a VW-Group EA288 TDI pattern, the Scala included; Euro 6 cars can additionally see NOx-sensor and AdBlue/SCR injector crystallisation faults.
Skoda Superb(2 issues)
- 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.
- Diesel particulate filter (DPF) clogging and regeneration failure2008-2020
The 2.0 TDI diesels (Mk2 and Mk3) suffer DPF problems, especially on cars used mainly for short, low-speed urban trips that never allow the filter to complete a regeneration. Symptoms include a DPF warning, repeated/incomplete active regenerations, raised idle, and rising sump oil level (and falling fuel economy) because diesel from post-injection regen dilutes the engine oil. Owners report DPFs needing replacement at relatively low mileage (e.g. ~52,000 miles). Active regen contaminating the oil was specifically noted by dealers on Mk3 2.0 TDI cars.

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 5 models.
