Have a BMW 525i 2007 and I am unable to reset TPM via local computer. When trying to reset TPM I get message:" Resetting TPM.." but never finishes. I want to disconnect the TPM module to troubleshoot, please share procedure. Thank you for your help. -J


I want to disconnect the TPM

I want to disconnect the TPM module to troubleshoot, please share procedure. Thank you for your help.

Disconnecting the TPM for troubleshooting is wrong. Ignore the individual who told you to disconnect it. If not an individual, and you came to the conclusion of disconnecting the TPM on your own, then with all due respect to your skills you are wrong.

Leave the TPM connected and scan for error codes. If codes are present, then post them so we can see them.

What exactly is the problem?

How did you arrive at the conclusion that the TPM is to blame for the problem you are having?

Hi Big Block 409, Thank you

Hi Big Block 409,
Thank you for your response, points are well taken.
Problem started when I had a flat tire and the "flat tire" warning amber light remained lit despite of the flat being already fixed. There is also a "TPM" amber light that comes up as soon as I start the car but it goes away on it's own. I have been trying to reset the TPM system using the on-board computer and system is not in "active mode", status is "reseting TPM" and backgroung is grey out but it never finishes the TPM resetting cycle. Also in "check control messages" there is a "TPM malfunction" message.
I took car to dealer and was told that they were unable to access TPM module with their diagnosis system tool. Reason why I wanted to unplug/plug, turn off/on TPM module.
Tires are P225/50R17 93V and know that tire pressure is critical, what value do you recommend for front and back? I live near Houston, Texas... very hot!
I have pictures of error displays if needed.
Thank you in advance for your help.

if the dealer could not comm.

if the dealer could not comm. with the tpm module, that's means it's off line.
frist thing to do is check the module's power,ground and data line.

Hi mws919,

Thank you for your help.
I do not have schematics or know the physical location of the TPM module to further troubleshoot present issue. I browse around but unable to find that type of information on my 2007 525i BMW, can you share any leads? procedure?

i do have just about all the info you'll need to get to the bottom of this, but we'll have to narrow it down a bit befor repairing any thing, frist is there any water leaks in the trunk?, there's a bulltin out for it and how it effects the tpm system.
just happened to set the light in the frist place?

Hi mws919, There are no water

Hi mws919,

There are no water leaks in the trunk.
It all started when I got a flat tire and the flat tire warning light came on and I thought that the system was smart enough to turn the flat tire warning indicator light off after the flat tire was fixed.
Later on I realize that there was a process to reset the TPM system and when trying to reset the TPM system got stuck on that mode ever since.

Thank you for your help.

Forget the dealer. Dealin

Forget the dealer. Dealin with a dealer is like havin the blind lead the blind. Are the tires and rims a size other than OE? If the tires and rims are “OE” then simply clear the code and drive the car normally. Post back if the same code (and or any additional) codes return. Answer to your question about tire pressure is 34 all around. Ignore those who say 32 all around here. It doesn't apply here. If you want a good laugh, ask them why?

Big Block 409, Tires and rims

Big Block 409,

Tires and rims are from original manufacturer and tire pressure is set to 34 all around.
Still unable to reset TPM because it is stuck as being resetted but cycle never completes, with following code: “Status: Resetting TPM..”.
The Status display on Control Display is “Gray” because TPM is not “active”. There is still the amber light indicating a flat tire that don't exist.
Any idea how to unplug/plug or turn off/on the TPM module? Just trying to make a change on the system...

Thank you again for your help.

Try this. Click on the menu

Try this.

Click on the menu button so you are on the main screen. Now click on the “I” in the middle. Scroll down to tires. At this point there will be an image of the car and all four wheels, and an icon (or button) that says "Reset". Click on reset. Check out the link below.

Big block 409,
Thank you for the lead, the process from you tube is the one that I have been doing. Is there any other process to reset the electronic modules in the car?
All four weels on the display are grey out which lead me to believe that a TPM module malfunction is possible; reason why I need to try and make changes on that module but have no idea where to start.

Try this. Disconnect both

Try this.

Disconnect both battery cables from the battery. Now connect both cables together for at least an hour. Let us know the results.

Hi Big Block 409, Thank you

Hi Big Block 409,
Thank you for the lead.
It is hard to believe but I do not know where the battery is located, I think that it is in the trunk but have no idea how to access it to disconnect it.
Please provide details, it is not in the owner's manual and still unable to found any information.

Cachaco The battery is in the

Cachaco

The battery is in the trunk, under the right side trim panel. To disconnect the cables from the battery, you simply lossen the nuts holdin the cables to the battery terminals. Use a wrench or a ratchet socket combination for this. Should be 10mm nuts. Make sure the cables are completely disconnected from the battery before connecting them together. To connect the cables together, you bolt them together through the holes in the cable heads. If the cables don't reach to connect together, then use the black clamps from a set of battery jumper cables to connect them. Use both black clamps. Don't use the red ones. Simply put one back clamp on the negative battery cable. and the other black clamp on the positive battery cable. Lay a floor mat across the top of the battery, just to act as an insulator. When the cables are connected together, you don't want them to touch either of the terminals on the battery. The link below will help. It shows battery location.

The TPM module is located beneath the spare tire in the trunk. I seem to remember a TSB (technical service bulletin) being issued by BMW for water getting into the trunk. Does water get into your trunk? Have you checked the TPM to make sure it’s not water damaged. Check with a dealer for that TSB.

Big Block 409,
I was able to find and disconnected battery, ended up with same results... TPM system is still stuck on resetting mode. Is there any way to test the tire sensor? Thinking about replacing the spare tire sensor with the one that is giving me issues...is that a good idea? is it easy to swap it?
There is no presence of water inside the trunk, found the TPM module and it looks normal..
I keep learning more things about my car.... THANKS!!

sounds like the sensor got broke when tire was changed, bring it back to who change tire.

Hi mws919, If sensor is broke

Hi mws919,

If sensor is broke it explains that flat tire warning indicator light is still on. Does the spare tire has a sensor? just trying to avoid buying all 4.
Why is there a TPM module malfunction? Why is the TPM system stuck in resetting mode? anyway other way to test/reset TPM system?
Thank you again for your help.

He started more than two posts for this. In one of his other posts he states he's been back to the shop.

J,

In terms of pricing a dealer is gonna cut you a new “A-hole”. You’re gonna have to take out a second mortgage on your house to pay the dealers bill. At this point about the only thing you can do (on your OWN) is replace all the sensors. You have to replace them all because they all have to be matched. I’ve used the kit below with great success. The entire kit is lees than one sensor for BMW. To install, follow the enclosed instructions exactly. Good luck. Keep in touch.

J,

Here’s another link. A few of my friends have dealt with this company. I never have, but my friends say they are good, so that’s good enough for me.
