P2002 on Jaguar
Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
P2002 on Jaguar vehicles indicates diesel particulate filter efficiency below threshold (bank 1). Au7o has documented this code across 2 Jaguar models — most commonly on XE, XF. 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 Jaguar range from $300 to $3,000, 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 Jaguar by Model
Jaguar XE(1 issue)
- Diesel Particulate Filter Clogging in Urban Use2017-2020
The diesel XE models experience DPF clogging when driven primarily in urban conditions where exhaust temperatures remain too low for passive regeneration. Repeated failed regeneration cycles coat the filter with hardened soot that cannot be burned off during normal driving.
Jaguar XF(1 issue)
- Diesel Particulate Filter Regeneration Failure2009-2018
Diesel XF models suffer from DPF regeneration issues, particularly in urban driving where the exhaust never reaches regeneration temperature. The DPF clogs with soot, triggering warning lights and reduced power. Repeated failed regeneration cycles can permanently damage the filter.

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