Default Tire pressure monitor problem solved

When I bought the car, the tire pressure monitor would not stay out. I read the manual and reset it accordingly. However, it would stay out for a few minutes, hours maybe then come back. Tire pressure was exactly on factory spec at all four corners.

After I replaced the RTAB's and had it aligned, this problem has completely gone away. So perhaps the "rear steering" effect of the bad RTAB's was being observed by the TPMS as a difference in wheel speed and triggered the warning.

So if your TPMS won't say out after being reset, and the pressures are right, this might just be the answer. My RTAB's were pretty bad, one had the metal sleeve completely torn loose, the other was about 60-70% torn away. The car would change lanes (just turn about 3 ft to one side) when exiting a curve at freeway speed. Yes that is as scary as it sounds.

Default Re: Tire pressure monitor problem solved

Ive done and had many customers complaints with these TPMS. What alot of people hate is switching them to a aftermarket rim and the new sensors may not work on the new rim. to fix this problem ive made a small metal container and weld it all up. place the tire sensors in this capsule you have made, weld a lid so its air tight.. screw in a air fitting and pressure ize the capsule. its alot of work but if your like me some customers and hate the anoying tire light this does work. Or if the vehicle you run with has a full size spare break the bead on the spare tire....and throw the sensors in your spare...just remember if you ever half to put that spare on...the sensors will break while driving...

Figured i would lay out this info if anyone has any concerns as well. Your Tire PSI should always be checked once a week. I always check mine when ever i wash my car.

on the e46 m3, there are no tire pressure monitoring sensors for the wheels. simply put, our tire pressure is monitored by rotation.

your reply does not apply or work for our cars unless you just wanna run tpms on each wheel.

Shadowless covered your error above. Next time Taunto you might want to take the time to RTFM so you know what you are talking about in relation to our M3s...

Glad I'm not relying on an incompetent like this for work on my M car...

Guys...

Come on, the n00b was corrected already.

There is no use in 'piling on' at this point.

He made a technically incorrect assessment of how the TPMS works on our cars, and the wiser veteran m3forum members chimed in to set the record straight.

Now that the correct information has been given, let's not tar and feather the n00b for speaking out turn.

To Taunto...

I strongly suggest that you read up on all the SPECIFIC details surrounding the E46 M3, before boldly commenting on any topic. (or this situation will surely repeat itself again and again) Posting technically incorrect information, only causes widespread confusion within the community. It can also cause a lot of unnecessary arguments, that I think we'd all like to avoid.

The internet is serious business. Step out of line and...

With that being said...

Guys please lay off Taunto.

He made a mistake in this case, but let's not bury the guy. He's new to the forums, so let's cut him some slack okay?

Everyone deserves a second chance, and hopefully he will double check his information next time, before posting a reply.

There's a difference. This particular idiot tried to tell us how he 'fixed' his customers cars. He's trying to masquerade as a professional while not having the slightest idea what he's talkng about and deserves no concesion whatsoever.

JM,

I know that, and I've been seeing that on the boards for many, many years now.

I think it's pretty clear he's been 'outed' in that respect, and your point is well taken.

All I'm saying is, let's just keep the personal jibes and comments out of the thread. There is no need in beating a dead horse.

/M Nobody, you may be on to something. I have researched this topic fairly extensively and not really come up with a good solution. My lights would come on mostly on long trips nothing in town. I just changed my rtabs and like you one of them was cracked all the way around. The other was almost all the way around. I was going through rear tires like crazy. I have not been on a trip since the change so I will check it out and report back.
