DESCRIPTION:
When diagnosing an unusual noise from the power steering pump or that steering requires extra effort due to low power steering pressure attention should be paid to the contaminants in the power steering oil.
Analysis has shown that the steering system could be contaminated with small particles originating from the manufacturing process of the power steering hoses. These particles may cause damage to the power steering pump. In these cases small metal particles can be found in the steering oil reservoir. See photos 1 and 2 in the attachment.
PRODUCT MODIFICATION:
An improved manufacturing process of the power steering hoses was introduced at structure week 2010w10 (see chassis ranges above).
SERVICE:
If metal particles are found in the power steering oil then flush the complete steering system with new fresh oil AND replace the power steering pump and reservoir according to VIDA. Flushing the system before replacing the pump will avoid repeat repairs. Follow the attachment for flushing.
