TPM Malfunction, which one is it?

Hi all,

Plenty of threads on this topic but I couldn't find any help as to how do I figure out which one has gone bad? Also how much do these little things run for? Been getting TPM failure notification and tried resetting many many times but no luck. Air is fine in all tires and all tires are good. I drive a lot for work, just hit 90k on my 2008 535xi, so I try to make sure the car is perfect. Thank you all.

Can you test by releasing several pounds of air from a specific tire and see if it registers low pressure? I would think that if the sensor is bad, it will not tell you.

I don't think just letting air out is going to work for you. Go to a Discount tire and have them scan each sensor, they will be able to tell you which one is bad. I will tell you this, if one sensor is starting to go out chances are the rest of them are on their way.

ZEEKHAN,
Hmmm, I wasn't aware of that and I find it interesting. My daughter's '08 X5, which has electronics very similar to the E60, has display similar to my '10 535 with green/yellow tires. The X5 owners manual shows two different systems.... 1) a FTM- Flat Tire Monitor which is ABS based and monitors tire RPM, doesn't have the display and 2) the TPM monitor which has green/yellow display.

Uh...yeah we do. Tires are green then go yellow/amber when low and red when flat.

As for the OP's question, TPM Malfunction vs a tire low warning usually indicates a system problem.
A sensor could be bad, the wheel well pickups could be damaged or bad or the receiver could be bad.
The receiver is under the plastic cover on the underside of the car and if the plastic cover gets damaged, it can allow dirt and mud and snow and rocks and well...all manner of crap to slowly kill that box.
My dealer replaced all 4 sensors and all 4 of the wheel well pickups before I pointed this out to them. They replaced that box and everything has been fine ever since.

Yes you guys are right. We do have the coloring thing for the tires. Sorry didn't realize that. So I tried the first thing for a little bit, took the air out from the front pass tire and the car didn't even say its low on air. Then I took air out from the front pass side and the car didn't say anything. All tires were green in color in I drive. ZLTFUL, those boxes or receivers that you are talking about located under the plastic, where exactly can I find them?

It is under the driver or passenger's seat. I can't remember specifically. There was a thread on 5series.net that I used to show them and of course, I can't find it now.

Hey guys, got an update for you. So I went to a shop, they had a scanner and scanned all my tire sensors and said they are all fine. They also said that the receivers could be bad as well but they Dont have a way to check those and Dont know anything about those. So I guess I'll look for those receivers as ZTFUL suggested.

TPM for Spare Tire

I was getting a low pressure reading, on my 2007 525i but all tires air psi was normal, then I read something about the spare tire having a TPM in the trunk, sure enough I aired the spare up and all was well.

Are you serious? Lol. I also read that there is some kind of device in the trunk under the spare wheel which can get corroded with water and stuff. Will check that once it warms a little.

Update: So after googling some more, I found out that there is a tpm receiver located in the trunk right below the spare tire (worst location). Which by the way is known to get flooded and make this device go bad... Look at the picture, how flooded that area is. The device and plastics were all in a few inches deep water. I dried everything but its not working. I'm thinking about purchasing this box new and see if that will fix the problem. What do you guys think?

Did it end up being the box that you actually took the picture of? Or was it a different box? Do you have a part number? Thanks in advance
