508

Defect

On affected vehicles the engine will run all the time and will not shut off in start/stop mode due to incorrect Body Control Module coding.

Remedy

Update the Body Control Module software.

Defect

On affected vehicles the Engine Control Unit (ECU) software is not according to specification.

Remedy

Upload modified software to the ECU.

Defect

On affected vehicles the Advanced Driver Assistance System (ADAS) functionality may not meet regulatory requirements and the Active Emergency Brake (AEB) and Lane Keep Assist (LKA) can inadvertently be deactivated by a long press of the ADAS button on the radio.

Remedy

On the affected vehicles the radio software will be updated by an Over-The-Air update which will be remotely checked as successfully installed.

Defect

The accessory roof rack for the Peugeot 508 saloon could detach from the vehicle if used to carry items other than a roof box.

Remedy

A full refund will be offered by the selling retailer (return of the roof rack and receipt) and recommend the customer purchase another solution to transport bicycle(s).

Defect

The filtering performance of the Diesel Particle Filter (DPF) may not meet the required specification.

Remedy

Replace the DPF on affected vehicles.

Defect

Certain rear suspension fixing bolts may not conform to specification which could cause them to break.

Remedy

Replace the affected bolts

Defect

The calibration of the engine management software could result in emissions of NOx which do not comply with the regulatory limits.

Remedy

Download new engine management software

Defect

The engine electronic cooling management control strategy and the maximum temperature alert threshold could cause the engine to overheat. This could result in a warning light and a message being displayed on the instrument panel.

Remedy

On affected vehicles download a new engine management software in order to modify the cooling management parameters to improve the control of the engine operating temperature.

Defect

An engine component may not be to specification which could result in loss of engine performance. This may lead to the engine stalling and potentially causing an engine failure. In very unlikely circumstances the vehicle speed may increase without warning but will stop on its own after a few seconds.

Remedy

On affected vehicles carry out a functional diagnostic check of the engine. If necessary replace the engine.

Defect

The positioning of the starter motor supply terminal may not conform to specification. Contact with a neighbouring component could cause a short circuit.

Remedy

On affected vehicles check the position of the terminal and where necessary reposition. Replace damaged components if necessary.

Defect

A possible nonconformity of an internal component of the starter motor relay could affect the control of the starter motor. This could adversely affect the starting operation and damage the starter motor due to overheating and in extreme cases there is a risk of fire.

Remedy

On affected vehicles check and where necessary replace the starter motor relay.

Defect

A component in the gearbox actuator may not be to the correct specification which may affect gear selection.

Remedy

On affected vehicles replace the gearbox actuator

Defect

The ignition module which triggers the front seat airbag may not deploy in the event of an impact. There is no indication to the driver the unit is faulty.

Remedy

Recall the vehicles that are likely to be affected and replace the front seat airbag unit.

Defect

The fuel heating device integrated in to the diesel fuel filter cover may be defective and allow heat to build up within the electrical supply connector causing the cover to distort and air to enter the fuel circuit. This could make the vehicles difficult to start and a warning light will be illuminated on the dash board. The engine could be difficult or not possible to start. In the worst cases a diesel fuel leak could eventually appear.

Remedy

Recall the vehicles that are likely to be affected and replace the fuel heater cover. Additionally the electrical connector will be inspected and where necessary replaced.

Defect

It is possible that a leak can occur between the injector spill rail connection and the plastic fuel return pipe. This can cause leakage of fuel which can either pool on the engine cylinder head and then become deposited onto the road surface where it could cause a skid risk to other motorist or if the fuel comes into contact with extremely hot engine components an exhaust manifold for instance it is possible that an under bonnet fire could ensue.

Remedy

Recall the vehicles that are likely to be affected to check the sealing of the fuel return pipe connection on each injector and if necessary replace the injectors as well as the fuel return pipes.
