Generation, production date, RHD/LHD, rear-axle steering, Power Steering Plus, drivetrain and the complete original label can change the rack specification. A 991 rack must not be assumed to fit every 991, and the 992 uses different families again.

Porsche 911 991 and 992 Years and Steering Variants
Both generations use electromechanical front power steering, but hardware and software revisions vary considerably across model phases and steering options.
| Generation or model | Typical UK period | Steering identification | Important compatibility check |
|---|---|---|---|
| 911 991.1 | 2012–2016 | Electromechanical front steering | Check Carrera, 4/4S, Turbo or GT application, RHD and full 991.347 suffix. |
| 911 991.2 | 2016–2019 | Revised electromechanical rack families | Rear-axle steering and Power Steering Plus option content can affect identification. |
| 911 992.1 | 2019–2024 | Electromechanical steering with integrated control | Check 0N1 without or 0N5 with rear-axle steering, software and RHD family. |
| 911 992.2 | 2024 onward | Latest electromechanical steering revisions | Do not infer compatibility from an earlier 992; verify VIN and current supersession. |
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 911 991 and 992 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.
991 label families
991.347.005.xx · 991.347.006.xx
Identification numbers seen on early and later 991/981-family rack labels. The complete final digits are essential.
991 service families
991.347.011.xx · 991.347.012.xx
RHD examples include 99134701137 and 99134701267, but model and option fitment must be checked.
992 RHD examples
9P5.423.050.D · 9P5.423.050.E
Parts information distinguishes D without rear-axle steering and E with rear-axle steering for RHD applications.
Do not mix steering-side families
992.423.050.D · 992.423.050.E
These appear in LHD catalogue applications and must not be substituted for the RHD 9P5 family without exact verification.
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 911 991 & 992 Electric Steering Rack Faults
- Yellow or red power-steering warning
- Heavy steering or intermittent assistance
- Knocking, creaking, notchiness or free play
- B200046 or B200000 functional-restriction entries
- Low-voltage or communication faults
- End stops or steering angle not learned
- Software mismatch after rack replacement
- Water, connector or impact damage
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.
Verified Porsche 992 diagnostic guidance
Porsche technical information documents B200046 with status 000700 on certain 2020–2021 992 vehicles as an adaptation/software condition; the same bulletin specifies different action for 000800 and 000900. Separate 2025 992 guidance records B200000 status 001050 or 001150 as a voltage-fluctuation/software issue where automatic rack replacement is not appropriate.
Porsche 911 991 & 992 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 |
|---|---|---|
| B200000 | Control-unit function limitation documented on specified model-year 2025 992 variants. | Check the complete suffix, supply voltage and applicable software action; Porsche states replacement is not expedient for the cited complaint. |
| 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. |
