The fidelity platinum warranty is not covering the cost to pay for my tpms, which have gone bad. Apparently, the tpms battery is dying and you can't replace the battery. One needs to replace the entire tpms system because the battery is somehow a part of the tpms unit!?!? The cost to replace 2 of them is $700. I am debating whether those tpms are really worth it.

Anybody have suggestions?
 
I have mine turned off in the MFI. I really don't think it's worth it in my opinion. With all the annoying warnings and beeping that thing makes it isn't worth it. I did fine with all the other vehicles I have had in the past without the system, I'll be fine without it in the Touareg. It's big $$ for a system that tells you your air pressure, and if and when it senses you have a defective wheel. Just my opinion
 
Check around, the stems are less than $125 each, tire rack and even Wal- Mart has them. They are often for sale on this blog, I bought four for my winter tires for $150. It' a great system when working and can save a tire and lots of fuel.
 
Wow, you dealer is ripping you off. The system does have it's advantages, but not $700 worth of them, IMHO.
 
Removal worked well for me. Granted, mine did work prior to removing it, but I did not want the extra expense of five new sensors for spare wheels I had for offroading. So I chose to ditch it in favor of silence and cost savings.
 
The valve stems are the sensors for the TPMS. They broacast a radio signal to an antenna located in the wheel well. Thats how the info gets to the dash and computor. The stem part should get replaced with each set of tires. The sensor should last 6 - 10 years. These Beru parts are now more available, check around for price.

The stems aren't the problem. The battery inside the tpms module are dying and given the battery can't simply be replaced (because of how its somehow connected to the unit) I am being told the entire tpms unit needs replacing.

Am I missing something?
 
Discount tire sold me 4 that worked just fine, about $100 each or so with the little rebuild kit. this was on an 08.

oh, and they weren't replacements but rather additional for the 18" wheelset. everything worked after wheel swaps, back and forth too. dealer things like that are almost always marked up more even from their supplier.
 
Good tire shops all over the country have been to training and have bought tools and supplies to work on these sensors. All cars and light trucks must have them. Customers are willing to spend money, this drives the market. Grap the phone book and start calling, if you don't get good answers, move on. Call the local parts store for recomendations.

I am in the situation now. My VW Real Driver Warranty covered the cost of a new module/sensor unit ($605 installed). But now the tire pressures always read 31 psi (even after resetting). And the unit is constantly in 'learning mode', trying to reset. My dealer service guy has been very good in working with me and we both are trying to get the wheel sensors to show a true fault code such as 'flat tyre' or 'defective wheel'. Once it does that we can get the warranty company to replace the sensors.

However VW itself is telling the dealers that if there is 35 months or more on the sensors, meaning the car is barely three years old from date of manufacture, then they will not guarantee the sensors. And if I was crazy and wanted to pay to have them changed the cost is $1000 for the 4 sensors and another $250 to install.

My service rep and I are hoping a fault code actually shows up. If it refuses to show any more faults well, guess what, I'm gonna pull the fuse and just use my eyes and trusty tire gauge on a regular basis, which I do already, and keep the tires aired properly. It's fascinating that the sensor has a permanently attached battery (cannot replace just that little five dollar battery), which means the sensors would technically be replaced every three to five years, or whenever the batteries die. IMHO it's a massive waste of mechanical resources and consumer money. But that's just my two cents.

I'll update in a few weeks if I get this thing resolved one way or the other.
 
The battery has to able to start and stop, spin over 100 MPH, and go over bumps, all in temps of -40 to 150. it has to be sealed up to surrive. The goal is 10 years. They will start to fail after six depending on miles and how there driven. No roadside flat tires and proper pressure at all times is worth it to me.

I hate to tell you, it is not that easy to disable the system. You will need a VAG Com cable as well as software to disable it. Your dealer may do it for you since you are having issues, but I doubt it.
 
Just have the dealer disable the warning code in the computer for tire pressure. Charged me a "fee" for this 10 minute task. Think it was $50 but thats a fraction of changing the sensors
