Audi laptimer, oil temp,. boost gauge activation

  1. Connect with module 17 – Instrument Cluster .
  2. Choose procedure 07 – Coding .
  3. Read stored value and back it up.
  4. Choose Long Coding Helper
  5. Select byte 01 .
  6. Enable box next to bit 03 .
  7. Save new coding.
  8. Exit.

Well if you have a D4 A8. You can definitely add the boost gauge and Oil temp Via Vag-com. It would make sense to me that you can add anything to the modules in the car that is available in the S8.

Here is stock —

Here is after the Boost mod Via Vag-com

And here it is in action. Nice rev limiter bar as well. It turns red just before you need to shift.
