Car guideVW group
Most 2015 to 2023 VW group cars with adaptive cruise use one harness that plugs in under the steering wheel. Cars without Lane Assist need one coding change.
Install
The gateway harness is the normal path. It handles cars with and without a factory lane camera.
Your car needs radar adaptive cruise control. Lane Assist helps but is not required on most of these cars.
Volkswagen listcomma sells one harness for these cars. The kit adds a harness box and a long cable to the device.
See the harnessThe gateway module sits above the pedals on the driver's side. You do not touch the camera or the OBD port.
Steering works down to a stop on almost every listed car. Cruise needs at least 20 mph or 30 km/h to set.
No Lane Assist?
A car with radar cruise but no Lane Assist can still steer with openpilot on most MQB cars. The steering rack has to be told that Lane Assist exists.
openpilot ships its own script that makes the change through the harness. The community wiki shows the steps for a Golf Mk7 without Lane Assist.
A coding tool such as VCDS, OBDeleven, or Carista can do the same on module 44, called Steering Assist. Cluster module 17 coding is optional.
Newer APA and VWBS steering racks use byte 3, bit 0. Older ZFLS racks use byte 0, bit 4. The openpilot script reads the rack type and picks the right one.
Newer cars need the hood open during coding. A wrong change can fault the steering, so work parked and keep a note of the original value.
This is a community-documented procedure, not official comma support. Sources are listed at the end of the page.
Know before buying
Platform matters more than badge. These groups are not covered by stock openpilot today.
Not in stock openpilot. Community forks run them with third-party harnesses.
These use FlexRay networking, which the community does not expect to support.
Code exists but is switched off. Steering cuts out every six minutes on that platform.
Some have a combined gateway that works in software but has no harness in the store yet.
On VW group cars the factory adaptive cruise keeps speed control by default. Our brand table shows how that compares with Toyota, Honda, Ford, and others.
See the brand tableQuick answers
By default the car's own adaptive cruise keeps speed control. openpilot speed control is an early option that only works with the gateway harness.
On most MQB cars, yes. The steering rack must be told it has Lane Assist with one coding change, described below.
No. Newer MQB Evo cars are not in stock openpilot. Community forks work on them, but comma does not sell a harness.
Those use a different network type called FlexRay, and the community does not expect support. The Audi Q3 is supported.
comma lists both with a VW MEB harness. Check the shop for that harness before you order a device.
Harness and kit facts come from comma's shop and its supported-cars table at one checked version. Coding facts come from openpilot's own configuration script and the community wiki. Checked September 11, 2026.
Confirm your exact model and year, then pick software.
