TPMS ECU not working?

[Dean P]

I have since replaced all the wheels with new wheels and new 433 TPMS. 3 of them display pressures. Driver's rear does not. I swapped the front wheel with the back but the rear wheel will not read (front wheel reads properly. Could the ECU have gone bad or could it be blocked??? Nothing else was changed, just the wheels.

I have rebooted, hard rebooted, factory reset and learn new pressure several time but cannot get the driver's rear TPMS to read. This have been going on a few months and I'm tired of seeing the warning label. Tire shop states the sensor works fine. Thoughts, comments?

A PITA, but I’d try a new sensor even though the shop says it’s fine. I’d bet on that, rather that the MCU selectively missing an individual sensor.

I put the old original sensor back in (5 weeks ago) and still nothing.

Made a service appointment for Thursday (at the new location here in St. Pete). Explained the situation and so far my bill is $184 and counting.

Does anybody know if there's one ECU per wheel or one for the car?

Any updates? I have the same problem but mine are the Bluetooth TPMS.

Scheduled to go in next week to pick up the part. Thinking about installing it myself but need to speak with them first.

Great, keep us updated. I'm 2 hrs away from the SC and they want me to come in for it even after I explained to them that it's not the TPMS in the wheel but the module inside the car that is faulty

Here's the update...wish I had better news.

They tried to sell me a TPMS (for the wheel). WTF!!! When I spoke with the service advisor, he knew exactly what I was talking about. I told them I only wanted to buy the TPMS module. Turns out they will not sell the module to a customer as this is a non sellable item. Tesla would have to diagnose the situation ($220) and if it is the module it would cost $65 plus installation ($shop rate). They stated "Chances are, it's the TMPS and not the module as they have never had one go bad". This would cost ($95 plus shop rate). Obviously, I frustrated as hell. Tesla does not work well with their customers unless you're willing to throw $$$ at the them. Be prepared...seems to be a common complaint.

Well, that sucks! I have an appointment in June to get it fixed but of course on their little invoice it says replace TPMS sensors in the wheel. I wrote them back and told them it's not the sensor but the module. I bet they will still try and replace the wheel sensor. Mine is still under warranty.

You shouldn't have any thing to worry about as everything is covered. Can you let us know what they did to fix it?

Sure will. I have to got to the SC on June 9th.

UPDATE: I just got back from the SC and guess what. It was the TPMS sensors. I say sensors because multiple sensors in the wheels failed. They had to replace a total of 3 which was covered by warranty.Both front and in the driver side wheel. So, I was wrong about the module. But wasn't expecting multiple since it only showed the driver side rear fail in the car and app. Weird!

Damn! I was hoping you were right! Maybe when I get some extra $$$ ill bring it in. Frustrating...

Thank you for letting us know.
