Defect

Suspension wishbone bolts may have been incorrectly tightened during the production process.

Remedy

Check and tighten wishbone bolts to the correct torque.

Defect

On the affected vehicles the operation of the brake vacuum pump may be affected by material detaching from the timing belt caused by the ageing of the engine oil.

Remedy

To rectify this issue a software update will be downloaded which will improve the vacuum diagnosis (in order to warn earlier about the risk of loss or reduction of braking assistance).

Defect

The rivet used to retain the curtain airbag in some vehicles could be incorrectly fitted.

Remedy

Check if the curtain airbag is correctly retained by the rivet and if necessary refit the curtain airbag correctly.

Defect

The operation of the brake vacuum pump may be affected due to material detaching from the timing belt.

Remedy

Check and if necessary replace the timing belt and other components of the braking assistance system including the vacuum pump. Additionally alter servicing schedules depending on usage.

Defect

The brake vacuum pump may be affected by material detaching from the timing belt.

Remedy

Update detection software inspect and if necessary replace vacuum pump and timing belt.

Defect

Front air bag igniters may not deploy correctly.

Remedy

Check and if necessary replace the affected front airbags.

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

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

It has been identified that the bonnet striker support may corrode. If this corrosion is not treated there is a possibility the bonnet striker support may fail which will allow the bonnet to open whilst the vehicle is in motion. Early warning signs or symptoms of corrosion can be seen by the driver around the bonnet striker support and on the leading edge of the bonnet also the bonnet may not lock correctly.

Remedy

Recall affected vehicles to inspect the area around the bonnet striker support and take preventive action to protect the area from corrosion which may include the replacement of the bonnet if required.

Defect

The fuel injectors supply rail could develop a leak over a period of time leading to a drop in fuel pressure in the injector supply rail which can affect the operation of the stop start system. In some extreme cases the engine might not restart and a spray of petrol under the bonnet may occur which is a fire risk.

Remedy

Recall the vehicles that are likely to be affected and check the fuel injector supply rail. Where necessary replace the fuel injector supply rail.

Defect

An oil leak could develop at the turbocharger lubrication union retaining bolt due to a non-conformity of this part.

Remedy

On affected vehicles replace the turbocharger lubrication union bolt and its seals.

Defect

The tightening torque for the front and rear right hand seat belt lower mountings may not be correct to specification. This could lead to the mountings detaching and in a collision additional injury to the driver.

Remedy

Recall the vehicles that are likely to be affected and rectify the tightening torques for the front and rear right hand seat belt lower mountings.

Defect

The fuel filter's integrated heater may be defective and could cause the cover to distort. This could cause air ingress and fuel egress. Either could cause poor starting and a warning light should illuminate

Remedy

On affected vehicles replace fuel heater cover. Check and if necessary replace connector.

Defect

The torque settings of the fixings of the front suspension fuel tank fuel cooler and the rear wheels have been set incorrectly. Consequences of the incorrect torque settings include abnormal noise and poor operation of the vehicle.

Remedy

Retighten to the correct torque value the front suspension fixings fuel tank fixings fuel cooler fixing and rear wheel bolts.

Defect

The front suspension lower arms may not be fully secure as the mounting bolts may not have been tightened correctly. The driver will initially be alerted to there being a concern because of the abnormal noise that will develop. If the noise is ignored over a long period it is possible the suspension lower arms may detach.

Remedy

Recall the vehicles that are likely to be affected to replace the suspension bolts and tighten them to the correct torque.

Defect

The supply terminal to the engine relay unit may have been over tightened and over time this could damage the component and cause the engine to cut out. In addition this could cause the diagnostic warning lamp to illuminate in error and it may make it more difficult to start the engine.

Remedy

Recall the vehicles that are likely to be affected to check and if necessary replace the engine relay unit.

Defect

The fixing bolts of the front LH and RH seat belt return rail may loosen and in cases of extreme force break.

Remedy

The bolts on the left and right- hand sides will be replaced.

Defect

The stroke of the brake pedal which could affect the slowing down of the vehicle may be in excess of manufacturer's recommendations due to the brake bleeding operation not being fully performed.

Remedy

Recall the vehicles that are likely to be affected to ensure the brakes have been fully bled and that brake travel is within manufacturer's recommendation.
