P2002 on Land Rover
Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
P2002 on Land Rover vehicles indicates diesel particulate filter efficiency below threshold (bank 1). Au7o has documented this code across 2 Land Rover models — most commonly on Discovery, Range Rover Sport. 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 Land Rover range from $200 to $3,500, 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 Land Rover by Model
Land Rover Discovery(1 issue)
- Diesel Particulate Filter (DPF) Regeneration Issues2010-2020
Diesel Discovery models suffer from DPF regeneration problems, especially when used for short journeys. The DPF becomes overloaded with soot and the active regeneration cycle cannot complete, leading to a blocked filter. Warning lights illuminate and the engine enters limp mode. Repeated failed regenerations cause the DPF to become permanently blocked, requiring expensive replacement.
Land Rover Range Rover Sport(1 issue)
- Diesel DPF Regeneration Failure in Short-Trip Driving2014-2022
The diesel Range Rover Sport suffers from DPF clogging when used predominantly for short trips. The DPF regeneration cycle requires sustained exhaust temperatures that are not achieved in city driving. The vehicle may attempt regeneration frequently, increasing fuel consumption and causing a diesel smell. If regeneration fails repeatedly, the DPF becomes permanently blocked.

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