Air suspension (compressor, air springs)
Signs: Suspension warning, the car sits low or drops overnight
Fix: Replace the leaking air spring; a worn compressor usually follows a leak

The Jaguar XJ (X350) was built from 2003 to 2009.
For this generation we cover 1 engines and 5 known faults, each with the mileage range where it usually appears.
The most expensive known risk is Crankshaft bearing failure / snapped crankshaft (V6 diesel): it usually appears at 100,000–250,000 km and costs €5,000–12,000 to fix.
In UK roadworthiness tests in 2024, at 150–200 thousand km this model most often failed on: lights, wipers and visibility (14.3 %), suspension (11.9 %), brakes (11.1 %). It fails less often than average on: brakes, suspension, tyres and wheels, lights, wipers and visibility, body and corrosion, exhaust, emissions and leaks.

|---|---|---|---|
| 2.7 / 3.0 TDV6 / SDV6 (JLR / PSA / Ford V6 diesel) | Diesel | Belt · 170,000 km / every 84 mo | 5W-30 · Ford WSS-M2C913-C / JLR STJLR.03.5005 · ~5.9–6.5 L · every 15,000 km |
Signs: Suspension warning, the car sits low or drops overnight
Fix: Replace the leaking air spring; a worn compressor usually follows a leak
Signs: Knocking from low in the engine, or sudden engine failure without warning
Fix: There is no sure prevention; frequent oil changes help. The repair is a rebuilt or replacement engine
Signs: No warning — if the belt snaps, the engine stops
Fix: Replace it together with the timing belt, tensioners and water pump
Signs: Limp mode, power loss
Fix: Clean or replace
Signs: Loss of power, whistle, smoke
Fix: Replace the turbo (labour is high: the body or the engine has to be lifted on some models)

2.7 / 3.0 TDV6 / SDV6 (JLR / PSA / Ford V6 diesel): belt · 170,000 km / every 84 mo.
The faults with the highest risk: crankshaft bearing failure / snapped crankshaft (V6 diesel) (100,000–250,000 km, €5,000–12,000); rear fuel-pump belt (changed with the timing belt) (150,000–180,000 km, €300–700); turbocharger failure (2.7 TDV6) (120,000–220,000 km, €1,500–3,500); air suspension (compressor, air springs) (100,000–200,000 km, €600–2,500). The full list by engine is on this page.
In UK roadworthiness tests in 2024, at 150–200 thousand km this model most often failed on: lights, wipers and visibility (14.3 %), suspension (11.9 %), brakes (11.1 %). It fails less often than average on: brakes, suspension, tyres and wheels, lights, wipers and visibility, body and corrosion, exhaust, emissions and leaks.
Before you buy, ask an authorised dealer to check by VIN whether the car has any open recalls. If the engine has a timing belt, ask for the invoice for its replacement: with no proof, assume it has not been done. On the test drive, watch for these signs: knocking from low in the engine, or sudden engine failure without warning; no warning — if the belt snaps, the engine stops. The full checklist is in the guide to buying a used car.
These models share engines with this car, so they share some of its faults too.
