| Notes for eliminating the noises |
| A closed hydraulic system will always produce running noise. |
| Noise is always produced when the steering is turned up to the end stops (this must only occur briefly). |
| The increased pumping noise in the steering end stops (during parking manoeuvers) is system related and technically unavoidable. |
| For noises that differ from the usual technically unavoidable operating noises take the following measures: |
| –
| Checking the hydraulic oil level in the reservoir of the engine pump aggregate → Chapter |
| –
| Check the feed pressure of the engine pump aggregate → Chapter |
| –
| Check the connections of the pressure line (expansion hose), return line (return hose) on the power steering gear as well as the engine pump aggregate (air in steering system). |
| –
| Check routing of the pressure line (expansion hose), return line (return hose) (lines pinched or in contact with other vehicle parts) |
