Due to an error in the manufacturing process the lower steering shaft universal joint may not have been produced to the correct specification. Under heavy steering forces it is possible for the column shaft to move within the universal joint connection.

Fix: Check dimensions of the universal joint and column shaft and replace where necessary.

On affected vehicles air lines and/or electric wiring may not have been correctly installed. This may allow them to chafe against the propshaft when the frame is fully powered. This may affect the ABS and if the spring chamber feed pipe is damaged cause the spring brake actuators to operate and lock the wheels on the rear axle.

Fix: Inspect affected air lines and wiring; replace where necessary; reroute airlines and wiring.

The electrical lines and/or compressed air lines may chafe through in the area of the second axle. When the electrical wires are abraded the wire can short and illuminate appropriate warning lamps in the cab. It is also possible though much less likely for the air line to the spring brake to abrade and eventually release sufficient air for the spring brake to apply and lock the rear axle. The service brake line is protected.

Fix: Recall the vehicles that are likely to be affected and correct the routing of the wiring harness. Replace the possibly chafed sensor and/or compressed air lines.

The exhaust tailpipe variants K7D K7C and K7N can become loose. Variant K7D can fall away from the vehicle leading to a heightened risk of incident for other road users. Where an exhaust gas leak occurs this can constitute a risk of fire.

Fix: Recall the vehicles that are likely to be affected and replace the seal of the exhaust tail pipe flange with a metal bead gasket.

The control unit for the steered trailing axle may crack due to a warped fixing bracket and allow the ingress of moisture.This may cause a short circuit. Normally a yellow fault message will appear and the system will immediately default to safe passive steering mode. However it is possible the defect may have an adverse affect on the performance of the axle whilst the vehicle is in motion.

Fix: On affected vehicles replace the control unit bracket Check and if necessary replace the control unit.

The Front radius angles in the driver�s and passenger metal seat base may not have been formed correctly and as a result the seat base may suffer from stress cracks which could compromise the strength of the seat base in the unlikely event of a rear end collision. The seat belt system is an integrated part of the seat.

Fix: Recall the vehicles that are likely to be affected to replace the driver and passenger seat bases.

On affected vehicles the steering may be considerably restricted due to a faulty steering angle sensor

Fix: On affected vehicles check sensor and replace steering gear including steering angle sensor if necessary

On affected vehicles the harness to the power distributor may chafe against a support bracket. In extreme cases the wires may chafe through and short. This can cause erroneous warning lamp illuminationor functional limitations to the transmission control or illumination equipment. Other consequential damage may also occur.

Fix: As a precautionary measure affected vehicles will be recalled to bring them up to the current series production configuration. The sub wiring harness will also be inspected for evidence of chafing and any damaged wiring will be repaired or replaced as required.

It is possible that the routing of the frame wiring harness could chaff on a right angle edge at a cable set bracket. This could result in a short circuit which should be identified to the driver by warning lights on the instrument panel before any damage occurs. However the manufacturer is taking steps to prevent any safety issues by recalling the vehicles.

Fix: Recall all the affected vehicles and replace the cable set bracket plus if required replace any damaged frame wiring harnesses.
