Problem 1
Peugeot 5008: AdBlue fault with a no-restart countdown
What goes wrong
The pump and heater built into the AdBlue tank lose pressure or fail, or crystallised AdBlue blocks the injector and lines. The car counts down the kilometres until it won’t start again.
How to check it yourself
Read the codes: pressure codes like P20E8 point to the pump in the tank, injector codes to a blocked or failed AdBlue injector. Look for white crystals around the filler and the injector on the exhaust.
The usual fix
The pump is sealed into the tank, so the whole tank is usually replaced; a blocked injector is cleaned or replaced. Ask the dealer about Stellantis’ extended AdBlue coverage before paying, and act before the countdown reaches zero.
Signs: Check engine light
Fault codes: P20E8, P20EE, P21DD, P20BD, P207F
Problem 2
Peugeot 5008: PureTech timing belt breaking up in the oil
What goes wrong
The timing belt runs in engine oil and slowly breaks up, especially with short trips and fuel-diluted oil. Belt debris blocks the oil pump strainer and the brake vacuum pump, which can cause an oil-pressure warning, a hard brake pedal, or a jumped belt and a ruined engine.
How to check it yourself
Treat an oil-pressure warning or a hard brake pedal as urgent: stop driving. A garage checks the belt width against the limit through the inspection opening (a special gauge) and looks for rubber debris in the oil and sump strainer.
The usual fix
Replace the timing belt, tensioner, and oil pump strainer, clean the sump, and replace the brake vacuum pump if it’s contaminated. Ask a dealer about Stellantis’ extended PureTech warranty and whether the engine has had the updated belt. Use the specified oil (PSA B71 2312) and change it on time or earlier.
Signs: Check engine light, Hard starting, Loss of power, High oil consumption
Fault codes: P0011, P0014, P0016, P0017, P0524
Problem 3
Peugeot 5008: High oil consumption on the 1.2 PureTech turbo
What goes wrong
Carbon clogs the oil-control piston rings, so the engine burns oil; some owners report around a litre per 1,500 km. Oil on the spark plugs can then cause misfires.
How to check it yourself
Fill to max and measure top-ups over 1,000 km. Look at the spark plugs for oily deposits and check the dealer history for an oil-consumption test.
The usual fix
Ask a dealer for the official oil-consumption test: engines that fail it may get piston and ring work under Stellantis’ extended warranty. Keep the oil topped up in the meantime.
Signs: High oil consumption, Blue smoke, Misfire under load
Fault codes: P0300, P0301, P0302, P0303
Recalls for the 5008
The most recent recalls registered with the RDW, the Dutch vehicle authority, across all generations of the 5008. Not every recall covers every car: a dealer can check yours with the VIN (chassis number), and recall repairs are free.
Wiper malfunction
The wipers may not work due to a fault in the vehicle monitoring system (VSM).
Possible consequence: This can obstruct the driver's visibility in bad weather, increasing the risk of an accident.
The fix: The vehicle owner is requested to contact the brand dealer. They will update the software of the monitoring system (VSM).
Door Opening Issue
The doors may not open from the inside when the key is in the ignition.
Possible consequence: Occupants may be unable to exit the vehicle after an accident or emergency.
The fix: The vehicle owner is requested to contact a brand dealer, who will perform a software update.
Motor control unit short circuit risk
A short circuit may occur in the motor control unit due to a manufacturing defect.
Possible consequence: The drive may suddenly fail, and there is a risk of fire in the vehicle.
The fix: The vehicle owner is requested to make an appointment with a brand dealer. They will replace the MCU (Inverter).
Automatic emergency brake system warning light
The warning light for the automatic emergency braking system does not illuminate if the front camera is blocked. The automatic emergency braking system operates in limited mode.
Possible consequence: Increased risk of an accident.
The fix: The vehicle owner is requested to make an appointment with a brand dealer. They will update the vehicle system management software.
Missing oil sprayer for piston cooling
An oil sprayer for piston cooling may be missing in the engine block. This can weaken and break the piston, causing engine damage.
Possible consequence: In the event of engine damage, power may suddenly be lost, increasing the risk of engine overheating and fire.
The fix: The vehicle owner is requested to make an appointment with a brand dealer. They will check if the oil sprayer is present in the engine block. If absent, the engine block will be replaced.
Wheel Bolt Tightening Issue
The wheel bolts may not have been tightened to the prescribed torque.
Possible consequence: The wheels may detach from the vehicle, increasing the risk of an accident.
The fix: The vehicle owner is requested to make an appointment with a brand dealer. They will check the torque of the wheel bolts on all four wheels and correct it if necessary.
