Porsche 991.2 Steering Wheel Part Number: Complete Guide

If you own a Porsche 991.2 (2016–2019) and need to replace or upgrade your steering wheel, getting the right part number is essential. The steering wheel is not only a primary control interface but also a key safety component tied to the airbag system. Using an incorrect part can lead to fitment issues, loss of functions, or even safety hazards. This guide explains the different steering wheel variants for the 991.2 generation and provides practical steps to identify the correct part number for your car.

Understanding Porsche 991.2 Steering Wheel Variants

The 991.2 generation offers several steering wheel designs, each with its own set of features and corresponding part numbers. The main variants include:

Standard Steering Wheel

The base steering wheel on most 991.2 Carrera and Carrera S models. It typically has a three-spoke design with multifunction buttons on the spokes (audio, cruise control, phone). It may be leather-wrapped or partly Alcantara. The standard wheel does not include the Sport Chrono mode switch.

Sport Steering Wheel (GT Sport)

Often referred to as the GT Sport steering wheel, this is a popular upgrade found on GTS and GT3 models, but also available as an option on other trims. It features a thicker rim, a 12 o'clock center marker, and sometimes exposed carbon fiber or Alcantara. It may also have a dedicated Sport Response button.

Heated Steering Wheel

Available across multiple wheel designs, the heated steering wheel includes a heating element and a temperature control button. The heating function adds complexity to the wiring and requires a compatible module.

Multifunction with Shift Paddles

Most 991.2 PDK cars come with shift paddles integrated into the steering wheel. The paddles are either conventional plastic/metal or the more premium magnetic paddles found on certain options.

How to Find Your Steering Wheel Part Number

To locate the exact part number for your car, you have two reliable methods: checking the vehicle identification number (VIN) or inspecting the existing steering wheel.

Check Your Vehicle VIN

Porsche uses option codes to track installed equipment. Your VIN can be decoded to reveal the exact steering wheel code. Several online VIN decoder tools (free or paid) can list the options. Look for code 438 (steering wheel leather) or 439 (steering wheel Alcantara) and whether it includes heating (code 269). The part number is often found in the parts catalog associated with that specific option combination.

Identify Options Codes

If you have your vehicle's build sheet or option sticker (located in the spare wheel well or maintenance booklet), look for codes like:

• 438: Steering wheel, leather
• 439: Steering wheel, Alcantara
• 449: Steering wheel, with heating
• XSX: GT Sport steering wheel (on GTS models)
• IW6: Steering wheel, multifunction, with shift paddles

Once you have the codes, you can cross-reference them with Porsche's official parts diagrams or consult your dealer.

Common Part Numbers for 991.2

Below are typical part numbers for popular 991.2 steering wheel configurations. Note that part numbers can vary by version (e.g., left-hand drive vs. right-hand drive) and production date. Always verify compatibility before ordering.

Heated Steering Wheel (Standard)

• 991.347.057.XX (basic leather, heated) – The exact suffix (XX) depends on color and stitching.
• For Alcantara heated wheel: 991.347.035.XX

Multifunction Steering Wheel with Paddles

• 991.347.036.XX (leather, multifunction, with shift paddles)
• 991.347.037.XX (leather, multifunction, without heating)
• 9P1.419.091.XX (GT Sport multifunction, includes shift paddles and center marker)

GT Sports Steering Wheel (without heating)

• 991.347.045.XX (leather, GT Sport, with 12 o'clock marker)
• 991.347.047.XX (Alcantara, GT Sport)
• 9Y0.419.000.XX (full Alcantara GT Sport with exposed carbon fiber)

Heated versions often add "H" to the part number or a specific suffix reserved for heating modules. For example, the heated GT Sport wheel may have a separate part number for the heater ring and wiring harness.

Upgrading vs. Replacing

When ordering a steering wheel, decide whether you are replacing an identical unit (e.g., same style) or upgrading to a different design.

Compatibility Considerations

• Airbag: The steering wheel and airbag module must match. The airbag part number must be compatible with the steering wheel model. For example, a GT Sport wheel requires a specific airbag unit (often triangular or circular) designed for that wheel. Using the wrong airbag can prevent proper deployment.
• Wiring: Heated steering wheels need a dedicated wiring harness and a control module that handles temperature regulation. Retrofitting heated functionality typically requires adding a control unit and possibly reprogramming the vehicle's central electronics.
• Shift Paddles: If upgrading from a non-paddle wheel to a paddle wheel, you need to ensure the PDK control unit supports paddle inputs. Most 991.2 PDK cars do, but the wiring may need to be extended or modified.
• Multifunction Buttons: The multifunction control module (SET/MEMO, volume, phone) is integrated into the steering wheel. Different wheel designs use different button layouts, so the new wheel must have the correct button set for your car's configuration (e.g., with or without adaptive cruise control).

Always consult a Porsche parts specialist or dealership before purchasing. They can provide the exact part number based on your VIN and confirm compatibility.

Final Recommendation

To get the perfect steering wheel for your 991.2, start by decoding your VIN to identify the installed options. Then, define your goal – are you replacing a worn wheel, upgrading from standard to GT Sport, or adding heated functionality? Once you know the option codes and desired design, use a genuine Porsche parts catalog (online or from dealer) to locate the specific part number. Do not rely solely on aftermarket listings; cross-check the number with official Porsche resources. Remember that safety components like the airbag must match the wheel. If unsure, pay a Porsche dealership for a few minutes of parts lookup – it is money well spent compared to ordering the wrong part. With the correct part number, you can order confidently and enjoy your upgraded steering wheel.
