Which year is your car? I had this same issue on a 2013 P85 and had to upgrade too.

I thought I responded to this question (and OP) a couple days ago with my thoughts and upgrade data.

I feel a bit guilty but when my older 2014 tire sensor alert keep appearing, I was convinced I wasn't paying $1200 to upgrade to the newer system that showed PSI. I rather enjoy checking my own tire pressure. So sure enough Tesla service said we need to upgrade you to the newer system I said no, just fix the system so the alert doesn't keep popping up. Service fixed it. They installed the newer system at NC. I don't think they were able to repair the older system. Actually I didn't really care what system, just wanted the stop the flashing alarm on the display about Tire Pressure Alert for no reason.

Just had that problem with my 2013 S. It was just one sensor that went bad and the bill was under $200.

Tire sensor batteries last around this long and they require new sensors when that happens. About $50 a corner. Changing out the system cost me about $500, half of which was labor. Not sure where $1200 comes from.

Same—2013 P85+. TPMS receiver failure eventually practically incapacitated all my steering stalk functions, including the gear shift, and had to limp ii 500 miles to service to avoid “thousands” in flat bed fees. They originally fixed it with the old Baolong unit and charged me ~$500 and I objected to not getting the newer Conti unit with individual readouts. The new unit requires different sensors, but the old sensors would have needed replacing soon anyway, so it was a wash. Having individual readouts alone is worth the hassle.

For my (now sold) 13 P85 I think I was quoted $700 in Scottsdale AZ last year to switch it to Conti. I even found the new sensors on ebay for less than what Tesla was gonna charge me in an effort to minimize the costs.

In case you wind up going that way- I got a quote from Tesla which had the part numbers on it and searched ebay for that part number to find a biz in Texas that had sensors.

BH- I had almost the same thing happen, still could shift into gear but got alerts one after the other of all my systems being non-functional. Like Ironman falling out of the sky after icing up. Well, maybe not so much. Power steering, braking, cruise, traction control, etc. Crazy that these things were connected somehow!?!

Labor was 206.25, so total cost was $600, not 500. Not something I perseverated on obviously.

@Richard
The symptoms were bizarre. I had a turning light constantly flashing and my reverse camera lines were wonky in addition to wondering whether I could get it into gear after a charge. Anything remotely related to the steering column didn't work properly. Definitely a white knuckle drive. I dropped it off when I picked up my new Model 3, so that was a distractor.

PrescottRichard | 17. Januar 2020

BH- That’s right, one of the ‘puddle’ lights was flashing too. I didn’t notice until driving home in the dark. Forgot about that. Makes me wonder how all that is connected in the column, seems like a bad idea! I think when I posted my symptoms here you mentioned the TPMS and I was perplexed, now I’m a believer :)

So the parts that I found for less $ are-

TPMS, WHEEL SENSOR, 433 MHz SILVER
VALVE STEM (soft cap) (1034602-00-C)

Didn’t save a ton, but IIRC it was at least half. Turns out my car (I bought it used) had a 4yr service agreement and that saved me as well.

It might not be your sensor. This is my experience:

I have a '13 P85+ and after the update the included tire settings, I was getting pressure warnings. What's happened is Tesla has CHANGED the tire ratings on the vehicle. If you're following the sticker guide on your car's frame, you will get the warning because the car is expecting a higher pressure -- you just don't know it and it was never communicated to owners. Your service center should give you guidance on the updated, recommended pressures, and they will put a NEW sticker on your car.

Save your money for the new Tesla Cybertruck.

The Tire Pressure Monitor was giving false alerts on my 2013 Model S ever since i got my car. Tesla replaced them completely while it was still under warranty. When the problem persisted after warranty expired, they recommended i upgrade to the newer system for about $1,100.

i took a chance on purchasing a TPM system based on my friend's suggestion who bought one on Amazon for $69.00 that he uses on his older BMW and so far it works pretty well. I purchased the 3-year Assurion extended warranty for $11.46 just in case the China-made product expires after the manufacturer's warranty.

What is the error message you are seeing? I am getting the following;

"Tire pressure monitoring system fault
Sensors unable to measure tire pressure"

with an error code of MCU_w012_TPMS

Anyone seen this before?

someguyinnj | 22. Januar 2020

oh, and this is in a 2018 Model S
