Recall records and data freshness
Recall context: are there safety notices to know about?
6 relevant recall notices appear for this model. Treat them as safety checks to verify for the exact car, not as normal MOT wear.
| 2022-01-11 | CATALYTIC REDUCTION (SCR) SYSTEM WIRING MAY BECOME DAMAGED BY CONTAMINATION Catalytic Reduction (SCR) system wiring may become damaged by contamination Inspect the SCR harness repair if necessary and fit protector. |
|---|---|
| 2022-01-04 | LOW PRESSURE FUEL PUMP IMPELLER MIGHT BECOME DEFORMED The impeller in the low-pressure fuel pump may become deformed causing fuel pump failure. Replace the low-pressure fuel pump with an improved part. |
| 2020-03-23 | ONE OR BOTH LED DAYTIME RUNNING LAMPS MAY FLICKER FLASH OR FAIL COMPLETELY One or both LED daytime Running Lamps may flicker flash or fail completely. Replace sealing gaskets and install gas absorbing sheets on affected units that operate normally. Replace any faulty units. |
| 2019-07-25 | SOOT MAY ACCUMULATE AROUND THE INTAKE SHUTTER VALVE ON THE INLET SIDE OF THE ENGINE Soot may accumulate around the intake shutter valve on the inlet side of the engine. Check clean or replace the intake shutter valve and update software. |
| 2018-09-17 | INJECTOR MOUNTING NUTS TIGHTENING FORCE MAY BE INSUFFICIENT The tightening force of the injector mounting nuts may be insufficient. This could cause combustion gas to leak from the injector and contaminate the engine oil within the cylinder head. This in turn could cause the engine oil strainer to become blocked. This could cause the engine to stall. Engine Pressure Oil Light appears along with the engine malfunction indicator. Possible Engine Stall without Warning Vehicles affected will have the engine checked for contamination and repaired / replaced if necessary. The Fuel injectors will also be re-tightened to the appropriate torque. |
| 2018-09-17 | FUEL INJECTOR SOFTWARE DOES NOT CONTROL THE ELECTRIC CURRENT CORRECTLY The Software controlling the fuel injectors does not control the electric current correctly. This may cause the injector control circuit to short circuit and cause the engine to stall. Results in possible Engine Stall without Warning Vehicles affected will have the injector control software re-programmed |
