out of nowhere....anyone ever seen this

 

I have not, but I'm betting you have a dead battery or two. I did have something similar on my SL and it was the batteries. I had the dealer turn TPMS off with SDS.

 

TPMS sensors generally last 5 to 6 years. So the question is have you ever replaced them?

 

yes they are all about 1 year old. bought them new when i bought my 19s

 

Pull the tpms module fuse for about 30 sec to see if it solves the problem, it works on the s class

 

will do, where would i find that?

 

that i don't know. if you cant find the fuse disconnect all the wire harness to the module to kill the power supply to it.

 

Oopss.. Wrong post. Post removed!

 

as a tire guy (my job) im gonna go with the batteries being dead. we see it happen all the time, sometimes on vehicles as new as 1 year old. most major tire shops around you should have a tpms reset tool (its like a diagnostic tool specifically for tpms). have them test the system, you might luck out and the system might just need to be reset, doubtful but you can hope. what they will be able to tell you is which sensors are bad.

 

But since they are a year old wouldn't it be highly unlikely that all 4 are going out at the same time?

 

did you buy oem benz ones, or aftermarket ones?

 

oem online with the tires

 

I have a set of OEM TPMS laying around in 315MHZ if you need

 

Thanks, ill let you know

 

FWIW I had TPMS issues for about 5 years, on and off. Replaced all 4 at a local tire shop (1/2 price of the dealer sensors) and no issues since.
