CLK Alarm Chirp & Center Console Trunk Release Light
 

I recently removed the wood trim piece that surrounds the shifter, window control switches and auto trunk release on the center console of my 2000 430 CLK. Once I had it unfastened I disconnected the wires from the ESP, window switches and the trunk release. After I re-connected the wires and re-installed the wood trim my alarm started making a constant low volume chirping noise. Sounded like a cricket :confused: Also the red indicator light on the trunk release switch constantly glows and though my keyfob locks and unlocks the doors as normal the parking lights on the exterior of the car no longer flash when I lock the car. I took the car to the dealer and they told me they could not find the cause and blamed it on my aftermarket stereo components. Their solution was to disconnect the siren for the alarm so that now when it is tripped all that happens is the parking lights flash. The audio system was professionally installed several years ago and these problems did not start until after I removed and disconnected the wood trim/wires. Does anyone have an idea as to how I can get the trunk release light to stop glowing and the exterior lights to flash and siren to work properly???

Did they(dealer) connect a scanner & talk to the PSE/central locking control unit? That is what controls the alarm system. The window switch IS also a computer & is on a NETWORK with all of the interior componets(ECU's) along with the PSE pump!

Thanks for the response - I don't know if the dealer performed those tests or not. Is there any way that I can reset the system myself?

What is the PSE pump?

PSE means Pneumatic Systems! Vacuum & pressure operated systems.
ONLY a scanner made for MB's will read problems in the interior CAN system.

Thank you for your help MB Doc - I appreciate youur time
