94 E320 - How Many Computers?

[cdanschwartz]

Under the passenger footwell in my E320 wagon is a VDO computer with the number 1245456532. I assume this is the cruise amp. Is that correct? I know that on some cars the Cruise Amp is located under the driver's underdash.

Behind the battery, after removing the plastic shield, next to the OVP Relay, is the Bosch HFM computer. Correct? Are there other computers here too? If so what are they?

Where is the computer that controls the convience features such as the power locks/alarm and the windows that roll up/down when you turn the key? Where is the computer that controls the HVAC? How about the one that controls the ASR? The ABS? The SRS?

How many did I miss?

Thanks,

Charles

I would have thought this would be easy for people who have replaced various electronics. Has no one ever replaced a computer on a E320?

The ABS or ASR controller is by the HFM controller. The AC controller is the pushbutton assy itself. The SRS controller (crash profile sensor) is mounted on the tunnel. The DM diagnostic module is under the dash. The lighting module is in the fuse box. The alarm is under the dash passenger side. The door lock PSE is under the rear seat. The seat module with memory is under the seat.
