tire pressure sensors
Does anyone know if you can disable the tire pressure sensors. If so any directions, looking to get rid of the error message. Thanks for any help.
Just in case anyone is curious this is not for a c-class but this thread seems to be the best for info.
Thanks again.

Tire Pressure Sensors?
I checked the WIS and there is an optional Tire pressure sensor available in the c Class. 4 antennas are mounted in each wheel well and the transmitter is fitted in the valve stem of each wheel. THe IC display shows the pressure of each wheel. The control unit fits in the rear near the SAM. It is activated with buttons on the steering wheel. Anyone here have this feature

Tire Pressure system for C class in Germany
The germans have a tire pressure system for the class. It's not exactly a tire pressure system like the E and S classes. There are no sensors in the tires themselves. Apparantly, its linked to the ESP systems monitors rotational forces on the wheels. I don't know too much on it but it appears to be a 100 dollar upgrade when you buy the car. Am Deutch told me about this. It just warns of low pressure but does not tell exact tire pressure. Maybe some of the Germans can enlighten us.

We had a 2000 Buick Regal with a feature like that. The traction control, or ABS system monitored rotational differences between the tires. If the air pressure became low in one tire, the rotational speed was different enough for the system to alert the driver. If all tires lost pressure at the same rate, such as when the ambient temperature rises or falls, there would be no rotational speed difference and no alert. I don't think it's a very sophisticated system, but that's what it sounds that you're describing.
It actually did work one time when one of the tires had a nail in it and was losing air slowly. I don't remember how many PSI difference it takes before it picks up the problem, but it's probably around 10 pounds or so.

Here is what the German MB forum talked about in regards to this system. Essentially it is what MarkL describes.
Beschreibung: Die serienmäßigen ESP-Sensoren übernehmen künftig noch eine weitere Aufgabe. Sie werden den Fahrer warnen wenn der Luftdruck im Reifen fällt und das obwohl der tatsächliche Luftdruck nicht gemessen wird. Das hat zum einen den Vorteil das in den Felgen wie beim normalen RDK die Batterien nicht gewechselt werden müssen und der Luftdruck permanet überwacht wird. Die ESP Sensoren merken wenn die Raddrehzahl sich an einem Rad erhöht, da es diese mit den anderen Rädern vergleicht. Das deutet dann auf einen geringeren Radumfang hin, welcher wieder auf einen abfallenden Luftdruck schließen lässt. Dann löst das System Alarm aus. Zudem werden weitere ESP-Daten für den Luftdruck analysiert, wie zB.: Querbeschleunigung, Gierrate und Radmomente.
I leave it up to the individual to *altavista or bablefish it* because I'm too lazy.

Description: The standard ESP sensors take over in the future still another further task. They the driver will warn if the air pressure in the tire fall and although the actual air pressure are not measured. That had not to have been changed on the one hand the advantage in the rims as with the normal RDK the batteries and the air pressure is permanet supervised. The ESP sensors notes if the wheel number of revolutions at a wheel increased, since it compares these with the other wheels. That points then on a smaller wheel extent, which suggests again a sloping air pressure. Then the system releases alarm. Besides further ESP data for the air pressure are analyzed, like e.g.: Transverse acceleration, greed rate and wheel moments.

Just reading about this in Consumer Reports (Nov 2003)...
Apparently, there are two types of tire monitoring systems:
Direct Monitoring - via individual wheel sensors
Indirect Monitoring - via speed differential monitoring
The indirect method only tells you if one (or more) of the tires is out of sync with the others. But it does not identify which tire has the problem. For this reason, I don't know how useful an indirect system would be. It's pretty obvious to me that the MB system being described in this thread is an indirect system.
The direct method gives tire specific information (hence more accurate), but requires tire removal to install sensors in each wheel. And naturally, it's more expensive.
Consumer reports lists four aftermarket firms that sell Direct systems, ranging in price from $204-$279, installation extra.
Intellivalve $249 -- Highest rated.
SmarTire (basic) $229
SmarTire (optional display) $279
Tire-SafeGiard )TPM-S204 $250
TireSafe $204

True statement MB-BOB. But its better than nothing. I can't tell you how many times I've seen drivers with a tire just about flat pulling out of a gas station without airing it up.

Tire PRessure UPDATE
I went to activate some features on my car and activated the Tire PRessure system. A new menu comes on the IC but the error message keeps coming up "Tire Pressure System Fault" I guess that's because the module is not installed.

When I ran the trapline on this, ravens1488 (MB mechanic in Germany), advised me that a car had to be built at a certain date (I believe 06/03) or later in order for this function to be activated. It required a software update as well. The reason he stated was that the software in earlier cars was setup differently and therefore this feature thru the ESP could not be done. HTH

that's one of the most complicated features I have. It is a OEM feature in Europe and other freezing counteries. There is a small heater that warms the radiatior fluid and circulates it. It uses the fuel but very little. It also keeps the interior warm. I will post pictures. There is a remote to activate it from 800 meters away. Also, My Instrument cluster has a new menu that will allow me to program certain times.

thats cool. i think TPS are really cool. when i was looking at mini's with my brother that was one of the features i thought were cool. would love to have that as one of those features i dont need but would be cool to have!
