11A is listed, but the option does not seem to work

I would start by checking the original build sheet and then compare the physical equipment on the vehicle. A sales or option code confirms the factory record, but it does not prove that every original component is still installed.

This sounds more like a documentation mismatch than a decoder error. Different databases often shorten the same factory description in different ways.

The wording may be abbreviated because these were originally production codes rather than consumer descriptions. “Accent stripe: White. This code identifies a factory paint, stripe, or exterior appearance treatment” is a reasonable plain-English reading, but the exact implementation should be verified for the 2020 model.

For a retrofit, check the modules, wiring connectors, software configuration, and compatible part numbers first. Installing the visible component alone may not make the feature operational.

The dealer should be able to pull a VIN-specific equipment or parts record. Ask them to search by VIN rather than entering only the three-character code.

Check the production month as well as the model year. Mid-year changes are one reason two vehicles with the same badge can have different hardware or descriptions.
