Coding

• When replacing this Mechatronic unit, if the old Control Module is still accessible, prior to replacement read/copy it's Coding and Paste it into the New coding line of the replacement Module.
  
• If the original Coding is unknown, coding information can sometimes be found in the pop-up balloon within the VCDS [Coding-07] function.
