112 ECU - Air conditioning
* A new ecu has been installed since R.P. 5424 in XM’s with automatic climat control.
I have no idea if they can be identified by the color of the sockets though. XM’s with a standard airco
have been equipped with a new improved evaporator sensor since R.P. 5471 and this sensor can be
identified by the lettercode. The improved ecu is marked 1PE, replacing 1P, stamped just above the
connector.
The partnumber for the improved version is 92 561 535. Reason for this change is that the evaporators
got frozen due to incorrect info from the sensor resulting in reduced or no airflow at all.
