Note:
The display groups "011" and "012" are only present in operating and display units with the Part Number 8L0
820 043 and the indices "H", "J", "K", "L" and from index "O" onwards (model with one display).

9.2 - Display groups 001 to 006

Display group 001:
Compressor shut-off conditions, voltage for magnetic clutch, at terminal "15" and signal for period "ignition off"
Notes:
◆ If one of the compressor shut-off criteria 1, 8, 11 or 12 exists, the magnetic clutch -N25 cannot be actuated
during the final control diagnosis (=>Page
◆ If compressor shutoff criterion "5" appears in addition to another compressor shutoff condition, disregard
shutoff criterion "5".
◆ If several compressor shutoff conditions exist simultaneously (display zone 1), the display will either show
them all alternately or it will show only the shutoff condition assigned the highest priority by operating and
display unit -E87.

switches to compressor shutoff criterion "3" (vacuum, refrigerant circuit empty).
◆ High-pressure sensor -G65 will gradually replace air conditioner pressure switch -F129 (as of model year
1999, initially vehicles with 1.6 l engines). As of model year 2001 only high-pressure switches -G65 are
installed.
◆ For vehicles with high-pressure sensor -G65, radiator fan control unit -J293 calculates the refrigerant circuit
pressure and relays no more positive signals to -E87 if the pressure is NOK.
