Just live with the symbol and check pressures manually periodically...what could we possibly have done for 100 years with no TPMs??

 

Well, I could do that. And if the gas gauge fails I could use a dipstick to determine how much gas I have left. Or I can post on this forum so that those who have an actual solution can offer their expertise. I think if a car has a system it should run properly, if possible. There is usually a simple solution. The part that is sometimes not so simple is finding the solution. Ignoring the problem is not what I would prefer to do, but thanks for the suggestion.

 

I'm sorry if I sounded abrupt. You can dig around my other posts to confirm that I've posted lots of useful suggestions to keep these lovelies humming along. I guess I'm just frustrated with $70 for a failed TPM (that have non-replaceable batteries!?!?!) and consider the whole technology a weak trade-off of new features vs. just more stuff to fail. My wife's Lexus has a switch to distinguish the snow tire/rim set from the summer set. Tire shops can check the actual output from each sending unit separately...and then, of course, sell you new TPMs, with a smile.

 

Thank you. Yeah, some of the new technology added to cars these days is a little good news bad news. It was simpler when you had to actually check all the levels yourself. Ah well, it's the days we live in.

 

It's important to purchase TPMS units that are programmed for your vehicle and are ready to pair. These are the ones I had installed: Titan TT-0033-0041 TPMS Tire Pressure Sensors

 

Thank you for the link. In my mind, the important point of my post is - the system was working fine before replacing the one sensor that was not working with the same type sensor in the working wheels. After replacing the malfunctioning sensor, the entire system went belly up. Why? Why aren't at least the 3 previously functioning units still functioning?

That's the Company where I ordered the sensors. They supplied the faulty sensor too, under warranty.

I went through this same hell with the TPMS on my ML350 and, like you, I wanted it to work properly! I'm not a "just put black tape over the warning light" kinda guy.

On my 2008, if a sensor dies or is otherwise not married properly to the module, the whole system fails. I believe later models are more fault tolerant. You will need someone with a TPMS scanner that can read the transmitters, or a MB Star system to check the TPMS module itself. The system should pick up things like tire rotations and new sensors, but not always as I have learned!

 

Here is an interesting thread on the Avin system installed in a GL:

Avinusa 9" Android head unit - MBWorld.org Forums

GL Class (X164) - Avinusa 9" Android head unit - So we recently purchased a 2012 GL550 to replace our aging family SUV. I decided to upgrade the stereo system given its limitations compared to today's head units. I did a lot of research and stumbled on this forum and read a bit about others...

Thanks, I just posted some information for those folks to help them out with the connectivity and the mounting brackets or lack there of.
