there

is

no

sensor

in

the

wheel

It uses the sensor attached to the ABS brake system (the one that monitors for lockup).

Ok...Ok....

so if the E53 works with the ABS to count the revolution to monitor the tire pressure... then which Bmw does this part work on.. ??

E60, E61, E63, E65, E66, E70, E90, E91, E92, E93, the cars with Most/CCC ie the bangle BMWs

Thanksssssssssssssssss.... very helpful, U just save me $375.... that's what the BMW dealer wanted to charge me to put this sensor in on new wheels....

forget that system anyways....it's pretty much useless. Just check your tire pressures when you fill up and you should do just fine.

Looks like a lot of the SAs do not know about this little ABS vs. TPMS nuance. I just spoke to a pretty good SA at Prestige BMW (he's been there for many years), and he also stated that the rim has the sensor. I told him that's not the case with the E53, that it counts revolutions per minute on the chassis.

And he said: "You know what...you're absolutely right....because you have the 06 right? OK, yeah, you're right"

I guess he knew it at one point, but he deals with so many BMW platforms, that he got the newer models "blurred" with the older ones.

That's what's so great about this Forum! You can get to know the details that even the experienced SAs have trouble with.
