don't forget key reminder chime - annoying
So I had my cluster replaced under the 10-year warranty of my 2003 S55 and now the "don't forget your key" reminder in the cluster also now chimes when entering and exiting the car. Very annoying! I have been though DAS Star diagnostics and cannot locate anything other than the seatbelt reminder chime option. Has anyone successfully configured to remove this audible chime for the key? or know the solution to fixing it?

Shardul,
will this disable the Keyless go functionality completely? and is this also where I can disable my TPMS function/warnings?
Thanks,
Mike

Mike, there is a TPMS menu in the IC cluster that you can turn on/off.
It will not affect the Keyless GO functionality completely if you turn it off in the cluster. Think of the cluster as a display device. It's a read-only device that gets information to display via the can-bus. Although there are user functions that come out of it such as folder mirrors etc, its basically is still a display device.
I have attempted to disable KeylessGo in the cluster (IC) menu but still it beeps when I open the door. I am wondering now if this is only part of it - maybe Keyless Go disable in the IC and something else in the cluster like rest of the world or something. If anyone know the answer to this, please share. Others have suggested upgrading the firmware in the IC. According to STAR there is no factory firmware option for the cluster that is visible in STAR DAS.

I have disabled the TPMS in the IC cluster at least 10 times and it always comes back...there must be another place for that too...I have been hitting the "Reset" button for 6 months now...considering dropping the $500 to buy new sensors from TIRE RACK.

there should be a TPMS section where you can disable it, or you may have to go into the CGW to disable it. I remember TPMS also being called RDK

What is CGW? I think the cluster portion is only useful to reset or re-enable the system after a tire repair, etc. I want to turn off the TPMS monitoring altogether, as all of my TPMS batteries are dead and I dont really think $500 is reasonable every 4-5 years for the sensors...maybe Im just too cheap...

CGW stands for Central Gateway Module.
Typically:
CGW is the primary gateway between CAN C and CAN B
Version coding known from EIS (N73) is now contained in CGW (N93)
CGW contains FSS plus maintenance programs, no longer in ICM
CGW module replacement: CGW module attempts to adapt to vehicle control modules. System diagnosis knowledge base updated by flashing.
Incorporates system diagnosis functions. CGW replaces system diagnosis module known from (R230) It monitors, evaluates and performs logic assessments of CAN B related components (later production CAN C will be included)
You can get an aftermarket set of TPMS sensors a lot cheaper than $500 if you search for it. I have an excellent link on my home PC and will check tonight.

I was able to disable tpms completely in my w211 e55, I remember going into 2 or 3 modules to be able to turn it off, it was such a pita, but yes it can be done.

chime disabling
I am still thinking maybe there needs to be more than one changed made to remove the chime. Still looking for a solution if anyone has one.
Thanks

Okay so I got the dam thing to stop. Another added benefit is the "don't forget the key" warning in the dash is also gone.
Happy happy joy joy .. I hated that chime
Anyway I went into the ICM module - special equipment
I had to change BOTH keyless go and key dependency to not present.
If you only change one it will not work. Changing the region to some other country does not work ether.

This may not be for everyone. Read the comment from the other forum
This is a really bad idea my friend...
You ask why?
What you did made the cluster unaware of the existence of keyless go...
If the remote battery of the key goes low, and antennas are no longer capable of detecting the key, while you're driving, the cluster WILL NOT turn red, and say "Key cannot be detected"
If you continue to drive, unaware of the message, the engine WILL shut down within 10-15 miles, possibly sooner, Needless to remind you of the steering performance when the engine is off (try it while parked, our cars have no mechanical lock), and most importantly, SBC has almost no effective stopping power without the pump and engine running, unless you step on the brake with 4 feet...

So the dude was right!
Okay so I completed a couple of tests today. I just had to test this because I just could not see the car just stopping.
So I started the car with keyless. Pulled the battery in the key fob and drove away. I have to mention I live in a very rural area. I did the test on a deserted two lane back road. No danger to me or anyone else. So I drove for 20 miles and everything was good,,,until I stopped for a stop sign. Just like the dude said the car stopped running. I could see this as a problem with no warning.
So I went home and put everything back to normal and tested again. This time I did not get out of the driveway and the light came on telling me no key detection. Actually I could see how this could be handy if you forgot your key on a gas pump or something and were in the next state before you knew it was gone. The more I drove the more frequent the warning became. About 15 miles and I stopped in the road. Sure enough it stopped.
So it seems the car will not stop as long as you are rolling. I could test again and see how long I could roll but I have learned what I needed to learn.
Car is back to normal and thats the way it will stay.

You can do what I did which was to removed the plug on the back of the cluster that connects to the chime. You still see the message " don't forget they key" and you don't ever get a chime for an error message. It's easy to do.

Plan B
I just could not live with the frickn chime. This time I went right to the source.
I disassembled the instrument cluster and found the noise maker. Instead of permanently cutting the wires I de soldered them. I then tucked the wires inside and reassembled the noise maker. This way it can be easily reversed.
This method seems to solve the chime problem while leaving all the dash warning lights functional.
