| Summary of components of engine pump aggregate TRW |
| The engine pump aggregate: |
| t | Is a complete component consisting of the steering hydraulics pump -V119- (electric motor and gear rack pump), the power-steering control unit -J500- and the hydraulic oil reservoir. |
| t | It is has a re-engaging protection after faults, failure or crash → Chapter. |
Note| t | No provision is made for repairing at the engine pump aggregate. |
| t | The cause of any problems which may be arising is determined by the pressure and tightness test. |
| t | If there is insufficient hydraulic oil in the reservoir always check the steering system for tightness. |
| t | If there is a leak in the area of the line connection first check the lines/line connections for tightness, if necessary retighten and wipe dry. |
| t | Do not use drained hydraulic oil again. |
| t | Always replace gasket rings. |
| t | Oil type: hydraulic oil → Chapter |
