Porsche Panamera Generations and Steering Identification
The 971 and current Panamera generations use electromechanical steering. Earlier 970 vehicles include different steering arrangements and should not be identified from a 971 part family.
| Generation or model | Typical UK period | Steering identification | Important compatibility check |
|---|---|---|---|
| Panamera 970 | 2009–2016 | Earlier or derivative-specific steering systems | Identify separately; do not use a 971 electric-rack number as a fitment guide. |
| Panamera 971.1 | 2017–2020 | Electromechanical steering | Check RHD, RWD/AWD, rear-axle steering and complete suffix. |
| Panamera 971.2 | 2021–2023 | Revised electromechanical steering | Verify production date, software and current supersession. |
| Current Panamera | 2024 onward | Latest electromechanical steering | Separate current-generation identification is required. |
Compatibility warning: a model name, year or incomplete part number does not guarantee interchange. VIN, RHD/LHD, option codes, full suffix, connector layout, software and photographs of the original rack must be checked before supply.
Porsche Panamera EPS Rack Part Numbers
These are identification and cross-reference candidates seen in Porsche technical or parts information. They are not a promise that the listed racks interchange.
971 main rack family
971.423.051.xx · 971.423.055.xx
Numerous suffixes exist for steering side, options, model phase and supersession.
RHD example
971.423.051.CE
Seen on a UK RHD Panamera application. The complete VIN and options remain necessary.
Service examples
971.423.051.DF · EP · BJ
Documented in later 971 parts listings; do not assume steering side or rear-axle-steering compatibility.
Bosch and wider references
7806994974 · 7806994205 · 4532002455
Cross-reference candidates associated with some 971 racks. Original Porsche label and VIN take priority.
Send the full number: spaces and dots may be removed on some labels, but every prefix and suffix still matters. The original rack label and VIN take priority.
Common Porsche Panamera Electric Steering Rack Faults
- Power-steering warning or heavy steering
- Intermittent assistance at start-up
- Knocking, creaking or free play
- Uneven or notchy assistance
- Low-voltage or network faults
- Water or connector corrosion
- Rear-axle-steering interaction
- Coding, calibration or alignment issues
A rack can knock, creak, bind or develop free play without storing a diagnostic code. Conversely, a warning code may be caused by battery voltage, wiring, communication, software, configuration or calibration rather than physical rack failure.
Panamera steering options must be identified
Porsche confirms electromechanical steering on the 971 generation and offers rear-axle steering on relevant variants. Front-rack identification and setup can differ with these options, so option codes and VIN are required before supply.
Porsche Panamera Fault Codes and Correct Diagnosis
Always provide the complete code, suffix or fault-status number and the control unit in which it was stored. Porsche bulletins show that the same headline code can require different action according to its sub-code and vehicle.
| Code or code family | Possible meaning | Checks before condemning the rack |
|---|---|---|
| B200046 | Power-steering control-unit functional restriction. Porsche bulletins use different status suffixes such as 000700, 000800 and 000900. | Record the complete status. On specified 992 and Taycan cases, 000700 can call for adaptation reset and re-coding, while 000800 or 000900 can require steering-gear replacement. |
| C10ACF0 | Power-steering limit stops not taught. | Carry out the specified steering-lock or end-stop learning procedure before treating the rack as failed. |
| U-code / no communication | Loss of communication with the power-steering control unit or implausible network data. | Check battery support, power, earth, connectors, CAN communication and related control-unit faults. |
| No stored code | Mechanical play, bearing noise, binding, water ingress or impact damage can exist without an electronic DTC. | Complete physical inspection, road-test assessment and checks of joints, mounts and surrounding suspension. |
