Hello everyone,

I am looking for a wiring schematic, AC DIAVIA, for Mercedes w124 diesel.
My car is a w124 E 200 D-year 1994 and has a DIAVIA AC aftermarket installed. My car was in workshop for body repairs and now the AC is not working anymore.
I try to figure out all the wiring and sensor.
Any help will be greatly appreciated.

I found some information about ECU-MAN here on this bulletin from DIAVIA but no schematic draw:

bulletin012

"ECU-MAN" - ELECTRONIC UNIT WITH MICROPROCESSOR FOR MERCEDES W 124 AND W202 MANUAL A/C SYSTEMS.
Attached to this bulletin is a copy of the technical description of the new "ECU-MAN" for Mercedes.
This electronic unit, compared with the previous system which also managed A/C and RPM controls consists of a smaller number of components and thus makes fitting of the A/C system simpler and more reliable, while now also performing controls and functions similar to the original Mercedes system.


Below is a list of the systems in which the new "ECU-MAN" unit is already used:

1MB24398E W124 200E - 220E 16V
1MB24498E W 124a 280E - 300CE - 320E
1MB24598E W124 200E - 230E
1MB24698E W124 260E - 300E
1MB24798E W124 200D
1MB24998E W124 250D/TD - 300D/TD
