8.1 - Encoding operating and display unit
Notes:
◆ After each coding, basic setting must be performed => Page
◆ If the display of a newly installed operating and display unit flashes (for approx. 2 minutes) after the ignition
is switched on, encode the operating and display unit and perform basic setting.
◆ The codes for the operating and control unit -E87 vary from the versions with part number 8L0 820 043 up
to index "E", indices "M" and "N" (model with two displays) as well as for indices "H", "J", "K" and "L" and as
of index "O" (model with one display).

8.2 - Coding of operating and display unit with two displays

Notes:
◆ Operating and display units with the part no. 8L0 820 043 up to index "E" and with indices "M" and "N" are
equipped with two displays.
◆ For vehicles with map-controlled cooling (for 1.6 l engine to be gradually introduced as from model year
2000):
- The codes for the operating and display unit -E87 are different to those for vehicles without map-controlled
cooling.
- A centre vent temperature sender -G191 is also installed (in air duct for "centre" dash panel vent).
- The -E87 must be adjusted to the other set-up for the engine cooling via a different code (the refrigerant
temperature is controlled by the engine control unit according to the engine load and is higher when the
engine is running at part throttle in comparison to full throttle).
◆
8L0 820 043 H A3 Fully aut. air cond. DXX
Code XXXXX WSC ZZZZZ
-> Only an operating and display unit -E87 with part number 8L0 820 043 as of index "H" can be installed
in vehicles with map-controlled cooling, as the map-controlled cooling coding is only recognised as of this
index. As the indices "H", "J", "K" and "L" are already allocated to a modified version of -E87 (use in series
production as of model year 2001), operating and display units with part number 8L0 820 043 and indexes
"M" (or "N" for Japan) will be installed until production has been reorganised.

8L0 820 043 H A3 Fully aut. air cond. DXX
Code XXXXX WSC ZZZZZ
-> As of model year 2000, the assignment of the ignition key is conveyed by the dash panel insert (data
telegram) together with the refrigerant temperature (when ignition is switched on). This information can only
be processed by operating and display unit -E87 with part number 8L0 820 043 as of index "H". As the
indices "H", "J", "K" and "L" are already allocated to a modified version of -E87 (use in series production as
of model year 2001), operating and display units with part number 8L0 820 043 and indexes "M" (or "N" for
