Octavia II Controller Coding

There are many options with the contoller units of the Octavia II which are configurable with the HEX CAN Tool from Ross Tech.

Warning - Modifiying the coding of your car and getting it wrong could render your car undrivable. Always make a back up of the original coding before altering it.

This guide will assume that you know how to connect VAG-COM to your car and that prior to every operation you will check for stored fault codes.

Controller 01 - Engine

Resetting the Throttle Body

Make sure that the ignition is on, the battery voltage is greater than 11.5V and there are no fault codes on the controller.

Select 01 - Engine and then Basic Settings - 04 and go to Group 060

Choose Go

It should say "Basic Settings: OFF" on the top of your screen, click [ON/OFF/Next] to turn on Basic Settings, it should now say "Basic Settings: ON" on the top of your screen.

Once you do this you will see the top right display say ADP RUN. The Throttle Body adaptation is being done as soon as you switched basic settings on. You will see the values change and hear the Throttle Body cycle for the first few seconds then it will stop.

Leave it in Basic Settings for about 30 seconds.

Click [ON/OFF/Next] to turn off Basic Settings, it should now say "Basic Settings: OFF" on the top of your screen, click the [Done, Go Back] button.

Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!
