Does the computer or anything else on a mercedes s500 have to be reset after the relays under the backseat are replaced?
Open the hood locate the fuse box on the passengers side near fire wall back feed 12 volts into to large fuse that is loose all by its self conected by 2 wires .I think its a 40 amp . By back feeding 12 volts into the system you can pop the trunk lid with the door switch.

yes they can but unlikely-more likely a bad over voltage relay(powers up idle speed computer) or wire harness-your vehicle is probably a hfm type fuel injection they changed from lh that year. find out if it is lh check the fuses in the base module located in the passenger side of the engine compartment under a cover held in by 4mm allen head bolts-alot of times these control units have intermittent contact with there connectors. asr stands for acceleration slip regulation-both isc and asr communicate via can system to monitor throttle position- ea isc cc-idle speed cruise control and electronic actuater(throttle)-hopefully i have helped

Hi there
First of all may i say i feel your pain. literally. the same thing happened to mine. here is what i did
Firstly i needed into a locked boot urgently (for wifes wheelchair)
so i cut a rectangle out of the boot put my hand in and pulled the release mechanism, that worked but left me with a hole in my boot.
I suggest that you try this instead.
remove back seat
the central locking pump is located next to the battery (black box with yellow air lines going into it.)
Unplugg the filler cap cover air line, then unplugg the boot air line and put it into the filler cap cover socket.
now when you unlock the car the boot should automatically open.
If it does not the problem it on the boot air line and you should strip the trim out of the boot to check, but you still have to get in and may have to do what i did initially.
If changing the air line worked then you will soon get tired of having to shut the boot everytime i solved this problem by routing the filler cap air line to a pnuematic switch (LEGO) This switches between the boot and the filler cap. bit naff but it works and cheaper than having to replace pump and have computer and keys re-coded total cost around £600.
op that helps

No,unfortunately it sounds like a bad body computer.Dealer only at the moment.

Your trunk lock actuator is probably in valet mode. Take the mechanical key out of your smart key(should have a release button on the bottom of the key which will allow you to slide the hidden mechanical key out of the plastic housing) insert it into your trunk lock actuator and turn to change your function of trunk actuator. In the valet mode the trunk does not respond to your central locking or release button commands. Your owner's manual will tell you about these features. I hope I have been helpful
