Tire Pressure Sensors Not Detected
I recently had all 4 tire pressure sensors replaced at America's Tire with DILL 1049, but now the system just says Tire Pressure System Inoperative No Wheel Sensors Detected. They initially installed the 351MHz sensors, which were wrong, but even after replacing them to the 433 MHz sensors, the sensors are still not detected. The techs said all sensors scanned just fine.
Before changing sensors, I was still seeing the options to reset or restart the TPMS. Now it just says no wheel sensors detected. I just spent $500 for the sensors & labor and now they're asking me to take it to the dealer. They must be doing something wrong to have the system recognize the sensors.
Anyone ever had to replace their tire pressure sensors with OEM sensors? I might just have them re-install the old ones in.

Thanks for the reply. I'm going to give them a chance to reprogram one more time. If they still can't be recognized, I'll just have them put back on OEM sensors made by Siemens. There should never be a need to bring it to the dealership each time sensors are changed.

I bought winter wheels from Tire rack.com and they were recognized right away and they were not oem. My guess is that they installed improper sensors. The dealer is going to charge you to tell you that too.

Same problem here. (2011 ML350) I wish a Mercedes Tech would chime in. I bought new wheels and winter tires last year. Went on TPMS247.com and bought 4 brand new sensors so I could have the guys at Costco put them in when they mounted the snow tires. They worked great all winter. Put the summer wheels back on in the spring, all worked great with the summer wheels and tires. Now mounted the winter ones, did the relearn thing with the dash reset button and it tried to find the sensors about 3 maybe 4 times but now it gave up and only give me the "no wheel sensors message" I'm assuming that it will only try a maximum amount of times before it goes into a fault that needs to be reset with star. I talked to the sensor guys that I bought them from and he says air the tires all the way down and then back up again to wake up the sensors in the wheel so they start transmitting again but I tried that tonight and nothing. Pretty sure because the car is not searching anymore for them. Hitting reset button on the dash does not put them into learn mode anymore. I guess I'll stop by the dealer and ask them if they can reset them for me and report back here.

Gotcha. I thought you meant that you kept using the same wheels, but swapped tires. Yeah, seems kinda weird that all of sudden they would not be recognized. You don't think you got a bad batch?... maybe all the batteries kicked at the same time? Awful good coincidence if it was.

Ya the chances of them all going bad at the same time is slim. I thought about setting the summer wheels next to them and see if they register but I'm 90% sure that the software has defaulted somehow and is not even trying to look for them. Otherwise I would get the searching or relearning message for a few minutes like it did when I first took off the summer wheels n tires.

You’ll be staring at a tpms failure message until you either disable it in DAS or install compatible sensors and have DAS detect them.

This happened to me a few months back, kept recieving a Tpms inoperative message so I got them replaced at discount tire, no fix same thing. Was told to bring it to Mercedes to scan, nothing, was told by mercedes that my battery needed changed. Didn't fix it either. It turned out to be the Tpms reciever. $300 part installed by Mercedes. Best of luck!
