I think the W123 did not have an electric vac pump, only started with the W126 (in the trunk) and the W124 (under the rear seat).

Allan, I assumed you had an electric vacuum pump as most all MB from about 82 on have them. Kaleb says no and he has a bunch of them. IF you have one, it would be in the spare tire well or under the back seat passenger side. It will be enclosed in a triangular shaped foam rubber for silencing, about 6 inches on a side and 4 inches deep.. Alarm failures are often blamed on the Bosch module which you will find under the passenger side carpeting or on the firewall, under the carpeting. A known good spare would be good here. Another point of failure is the electric switch on the drivers door latch, operated by your key. When this contact sticks, the alarm thinks you are being thefted. The switch will sometimes change position in the middle of the night, setting off your alarm. Cleaning the switch will often fix the alarm problem. Now VERY curious to know if you have an electric vacuum pump Good luck, Jim Friesen Phoenix AZ 79 300SD, 262 K miles 98 ML 320, 145 K miles _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
