A little TPMS help please.
I got some aftermarket valves from DTD, for my winter set up. I followed the instructions in the owner's manual for resetting the system in the car, but I am still getting the red cluster warning. I noticed I only get it once and then the little tire light comes on in the tach after I press ok. If I would have known that is all that happens, I wouldn't have put them in at all. Anyway, I have prior experience with TPMSs, but the one in this car seems screwed up.
This is embarrassing. Could someone run through the set procedure for me, so I can see if I am doing it correctly?
Thanks.
Bryan

I don't know much about who did your wheels for you, but when NTB broke one of mine off, they had to ship it to the local dealer for them to fix. MB said that they have to plug the car into STAR to tell it to talk to the new sensor and vice versa. Don't know how much truth is to it but they did, and now it works on mine.

That much i don't know. I've read alot of folks on here switch back and forth between winter and summer but I've never heard of them having to take the car back and forth to MB to have it done. It would seem rather silly, but in my case I guess it wasn't.

I have original MB TPMS and another set from TireRack.com in my summer and winter wheel/tire units, and the car learns the presence of the sensors after a few miles and the light goes out once, and stays off all season, presuming no loss of air. Some other factor must be at work in your car.

UIpdate: Just spoke with my salesman. He said he had to reset three yesterday and they keep coming back on due to the low temps (5 degrees fahrenheit). I'll wait until warms up a bit to see what happens next. Lame.

My SR told me the fluctuation of temp is causing mine to go whacky from time to time after calling him about my problem.
Mine came on warning me about tire pressure when it was about 40 degrees and raining. I checked the pressure and everything looked correct. The next day..no warning and was about 59 degrees. So far so good no more warnings.
I'm using the OEM TPMS on aftermarket wheels. First time i've had a problem with it but seems the problem went away after it got a bit warmer.

Yesterday on the way home, it was 29 degrees. I reset it once at the beginning of the trip and never heard from it again. This morning at 10 degrees, it was acting up again. It must be the temp. It supposed to hit the low 30s here this week, so I'll report back.

Assuming the sensors are not malfunctioning, your tires are not properly inflated for the range of temperatures you are experiencing. For example, my winter tires had been stored in a shop at about 70 degrees. When they were installed, I asked to have them set at 38 psi. With anticipated outdoor ambient temps in the teens and twenties, 50-60 degree loss equals 5 to 6 psi loss, which would result in 32-33 psi while driving in our typical winter. Not one alert all winter so far.
Do you park indoors at night? If you are checking your tires first thing in the morning before driving, you also need to allow for the difference between the garage temp and whether the tire has actually cooled off to ambient by the time you roll into the nearby service station/air pump.
Bottom line: It is not inevitable that you get alerts in the winter.

Yes, but when you reset to current values, wouldn't that change things? My car is indoors night and day. Anyway, it's definitely the temp. It was really cold this morning and I kept getting the alert. I went out at noon. It was 35 deg. I reset the alert from this morning and did not get an alert again for the entire hour that I was out. Now that I know what the problem is, it doesn't bother me. Did they not test the W204 in extremely cold conditions? Maybe they left some stuff off for the tests.

1) Measure temp in your garage at home before leaving for work
2) Decide down to what ambient temp you want to be "protected"
3) Gently, slowly, drive straight to nearest air pump, hopefully a mile or two at most.
4) inflate to recommended pressure, plus 1 psi for each ten degrees F difference between your garage temp and the low end that you anticipate
(Example: If recommended is 32psi, your garage is 60F, and ambient is 10F, so you anticipate a 50 degree drop from your garage to the outdoors....32+5 psi=37)
5) Then reset, and you should be without further concerns until the seasons change again.
By doing this type of procedure, I never get a pressure alert in the cold.

It would depend when you RESET. To start from a "clean slate"

I'll give a try, but since I know what the problem is, as I said earlier, it no longer bothers me. The procedure I had been using was working great.
1) Don't drive it during winter.
Anyway, thanks for the help.

How do you know your sensors are compatible with your car's system?

TPMS stuff
Same thing this winter and the snows are off already. Reset and it's done.
BTW, our lowest temp in December was 17 deg f and the TP system took no notice.
At no time was the car plugged for a STAR reset.

No, you do not. Last winter when I installed my winter wheels with compatible sensors from Tire Rack, all I did was reset the system. And when I reinstalled the summer tires it was the same procedure.

Yup, he's right.
