P2002 on Jaguar by model: symptoms, diagnosis and fix
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.
Common Symptoms
- DPF warning light on dashboard
- Reduced engine power
- Increased fuel consumption
- Strong diesel smell from exhaust
- Engine management light
How to Fix
Perform a forced DPF regeneration via dealer diagnostic tool. If the DPF is heavily blocked, chemical cleaning or replacement is required. Adopt a driving pattern that includes regular highway runs of 20+ minutes at 2,500+ RPM to allow passive regeneration.
Owner tips & cautions
- TipTake the XF diesel on a 30-minute highway run once a week to allow passive DPF regeneration. Short urban trips are the #1 killer of diesel DPFs.
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.
Common Symptoms
- DPF warning light illuminated
- Reduced engine power in limp mode
- Increased fuel consumption
- Frequent regeneration attempts (high idle in park)
- Engine management warning light
How to Fix
Perform a forced regeneration via dealer diagnostic tool. If the DPF is over 80% blocked, professional chemical cleaning or DPF replacement is required. Change driving habits to include at least one weekly 20-minute highway run at 2,500+ RPM.
Owner tips & cautions
- WarningDo not buy a diesel XE for pure city driving. The DPF needs regular highway runs or it will clog and require expensive cleaning or replacement.

Frequently asked questions
What does P2002 mean on a 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 it is documented across 2 models: XF, XE.
What are the most common causes of P2002?
The most common causes of P2002 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P2002 on a Jaguar?
Published repair estimates on Jaguar range from $300 to $3,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
