Swap Tire Pressure sensor
Will there be an issue swapping out the OEM tire pressure sensors from my 2004 S500 wheels and reinstalling them on a set of OEM rims/tires taken off of a 2007 S550?
I searched the forums but could not find anything.
Thanks in advance for any help...

make sure you put them back in the same wheels.....
ie. Right front back in the right front of the new wheel....
That way they dont have to reprogram the system!!

some of the 07's still have the TPM's that have the serial #'s that get programmed into the control unit.. It will pick up the sensors... but what i have seen, it will still throw a TPM light or it will read the pressure and show it on the wrong wheel in the screen... The newer cars run off rolling diam and dont show actual tire pressure, just warn the driver of a "low tire".....

I believe that the sensors have to be programed for your car's VIN, and are not interchangeable.

that is BS. None of the newer sensors have anything to do with the cars VIN, and yes they are very interchangeable.
Since all cars made in the US after 2008 will be required to use some sort of tpms on ALL of their vehicles by federal law, There will soon be a lot of non proprietary adaptations available. Many of the foreign car manufacturers had already started preparing for this since 2003 to date with the introduction of the 315mhz and 433.92 mhz systems.
Mercedes uses the 315 mhz system since 2003 or 2004 so any sensor that outputs 315mhz and actually fits in your wheels will work and has nothing at all to do with the car's vin.
Once a reading is stored in the computer, the car will alert you if you have lost a certain percentage of air in a certain wheel I think its like 10 or 20% of a preset value.
This is how it knows which wheel is low ( or High ). So this is simply a receiver transmitter function based on a prestored setpoint. This setpoint can not be altered without programming.
On systems that are non user programmable, the sensor's ID is stored in the cars computer so it knows which sensor is in which wheel by programming.
The nicer user resettable/programmable systems like the 2004-2006 S have
receivers that upload all of the transmitted sensor information and stores it when the R button is pressed. It then compares "learned" pressure reading with the preprogrammed presets mentioned above for each wheel and determines if an alarm is sent.

are you sure? The system has no idea which sensor is where except for the current signal it is seeing. Therefore if it is reading 38psi from the rt sensor and 37psi from the left, that should be what is shown unless that was a pre existing condition before the change out.. otherwise it could be the cables were switched but again I don't see how that could be.
Try reset and let the system find the pressures again.
