OBDeleven Coding Devices

How it works

A small Bluetooth adapter plugs into the car and the work is done from an app on a phone or tablet. Ready-made one-click apps mean the common settings can be turned on and off without any coding knowledge.

What can be unlocked

• Automatic mirror folding on locking
• A digital speed readout in the instrument cluster
• Daytime running light brightness and coming-home lighting
• Adjusting the seatbelt warning chime
• Rain sensor sensitivity and the number of comfort indicator flashes

Which cars

It works on Volkswagen, Audi, Seat, Skoda and Cupra vehicles. What can be unlocked varies with model year and trim level, so the list is not the same on every car.

Is it safe?

Coding changes parameters inside the factory software; it is not flashing new software. OBD Eleven can undo the changes it has made, which gives you a safe footing while you learn. Noting the original values first remains a good habit.
