This is prettymuch whats going in with mine. Maybe I should take it to the dealership

 

Not tryin to be a smart ***, but nobody has seemed to discuss just doing away with tpms all together.


such a pain those things are.

 

So true. There is so little volume in these tires, do you think that a functioning TPMS could save your bacon with a flat tire warning? I'm thinking yes.

 

I would 100% get rid of them. They are absolutely useless to me.

 

I'll take the opposite side ---- I like TPMS.


1. TPMS is meant as a warning about low pressure. If you keep driving a low pressured tire, heat builds up until the tire explodes.


2. As neurotic as I am, and since I drive far and with nutty behavior, I almost always walk around the car to check the tires before hopping in. With TPMS, now I don't have to walk around. I just sit tight and enjoy.


3. TPMS saves me a lot of time. I used to check my tires almost once a week or every other weekend. Prior to TPMS, I would waste minutes checking tires. Wasted minutes means that I put forth the effort in checking but the tires are okay to begin with.


4. Everyday, my gauge reflects my tire pressure. I would want to know driving at high speed how my tires are doing. I don't care for the MPG, average speed, etc. --- I care about my safety and TPMS gives me that.


I am unsure what the deal is with having to replace these once every 4 or 5 years --- perhaps, I am missing something here.

BTW, I thought in a few years, it will be mandated that TPMS becomes a standard.

 

the OEM TPMS when in working condition should perform Flawlessly at all times until they are completely worn and done.


I have a 07 and replaced mine recently.


It is a hefty amount but it lasted 7 years so I can't complain.

I love them when working properly.

 

I can agree with advocates of tpms in some areas...


but, checking your own tire pressure allows for the owner to inspect other things on a more routine basis.... visual brake inspection.... wheels, body,paint,etc. if your in the **** camp, id think one would manually check em weekly .




Besides... I found mine on a few past cars to not be right on anyways.
and I checked my manual tire gauges (3) and they all checked out equally.

 

Yup! The factory is never accurate --- ever! When i do add air, I use my Accutire.

Still, the factory TPMS serves multiple purposes.

 

+1 for checking the car visually on a regular basis and manual tire gauges.

Thanks, whoever said that.

 

Use these: http://www.oewheelsllc.com/TPMS-Sens...e#.VDBBv2ddWSp

$136-$184 for set of 4 w/stems depending upon model. Porsche price is ~$175 per sensor uninstalled. Just make sure you have correct year and model when ordering.

Take them to a tire shop to be installed. Should be about $25 per wheel.

Save yourself $750-$1000 over what the dealership charges! Lots of threads on the 997 turbo forum if you want corroboration. Best,

 

Now that it's getting colder in CA, I realize that the one tire sensor that's always acting up (rear right) is normal in the morning when it's cold. As soon as the car or the day warms up, then the rear right TPMS shows the error that it can't read tire pressure

 

Mine were acting a little goofy a while back, colder temps setting in. It would give the low pressure warning, saying to add air. But they were only at like 31 front and 33 rear and it was cold out. I've had them show up lower on a cold morning than that without error. So I added some air, got them up to like 36 and 39...still had the warning. ASSumed the sensors were going bad and took it in. Service writer took it back and aired them WAY up, like 40 front and 44 rear and it went away. I came home and set the pressure lower/normal and have had zero problems since. For whatever reason it seems you have to air the $hit out of them to get them "reset". Something for the memory bank

 

My understanding is that the battery in the TPM is designed to last seven years from the date of activation. Three of them went out in my '08 within two months, on separate occasions. I paid big bucks to replace them each time.

For those using aftermarket, have you had any issues since installation?

 

I've been really looking closely at my TPMS recently, trying everything to get that stupid error to go away. Filling up with a lot of air, resetting, trying winter tire setting, back to summer tires setting, etc. prettymuch everything. Here's what's weird and something that my OCD noticed. The sensor is totally fine and reports no errors until the outside temp reaches 60 degrees. Exactly 60 degrees every single time ! As soon as the outside temp reaches 60, the TPMS will throw the error and not be able to monitor that one tire (passenger rear) what the heck is up with that ?!

 

After spending around $800 (including changing all sensors) with no resolution, I decided I'd had enough flushing away good wine money on the problem and had "a friend" disable the entire system. This has to be done using a computer/durametric. You cannot simply disconnect the mother module. I now check my own tire pressures about every other week, and I'm fine with that. If I have time for cleaning and vacuuming my car, then I have time to check my tire pressures while I'm doing it as well.
