Ok, in short the eBay sensors I got are PERFECT, they work flawlessly and were $45 w/free ship. This is a tidbit to help others afflicted with moderate idiotism to not pull there hair out like I did...

So, had the new sensors installed. No matter what other sources state NO MANUAL RELEARN PROCEDURE IS REQUIRED. Didn't even have to drive one foot, as soon as I started car they all sprung to life. Drove about 25mi and got the damn TPMS system inoperative warning on the dash, cussing fit ensued. Went back the next day to the shop, same all good for 20-25mi then warning message, and checked all the sensors with their tpms scanner and all showed working. BTW, each one of our sensors DOES put out the actual pressure, it's just that our clusters don't convert it for display....damn it!!! Drove it again and again and again and again hoping they would mate up but the same end result every time. Then I had an epiphany. Because I like to think I'm smarter than I am I had told the shop to save my sensors as I was going to open them up and have a look. Well, with the sensors sitting in my back floorboard they WERE STILL REGISTERING WITH THE MODULE, thus confusing the hell out of it. I removed the old sensors from the car, drove off and NO ISSUES SINCE!!!!

Ok so you jumped around a lot...

so basically your old ones were still registering when they were outside the vehicle, messing everything up? Which yea, makes sense.

If I read it correctly. Link to sensors?

jptaylor

No, the old sensors were still INSIDE the car...but yes, they were still connecting to the TPMS module and confusing it

...and i said eBay but it was amazon

Be kind to yourself. At least you figured it out before you went and spent more money. Either that or the old ones would have come out all on their own and you'd be like "for some reason the new ones just started working". I can totally see how this could happen, and I think you did alright.

Pls post up the link to the ones you bought.

Oh and I'm not an expert on this, cos I'm in Canada and it used to be the cars there didn't use TPMS, so my 08 and 09 did not show pressure values, but my 2012 does, and it shows them individually. I think that's a PFL/FL thing.

Good catch buddy, i was also wondering about the TPS sensors, I just bought a 2012 c63 and when the winter comes in Canada i was hoping to install the sensors on my winter tires. Any suggestions on where to get them online and which ones work. Also, like the poster said there is no work required to program them is this true with 2012?

jptaylor

the link is in my post above.....

....and i swapped in my FL cluster just to see if i was right and I'll be damned if the individual pressures dont show up....there they are, plain as day....now if my FL multifunction switch would just come in i could leave this FL cluster in place and be good to go(Cruise control doesnt work without the FL stalk assembly)

Polish-C63

I tried the link, the item is currently unavailable that's why i was looking for alternatives. Saw this on ebay:

http://www.ebay.ca/itm/4x-NEW-MERCED...dWl4fA&vxp=mtr

And still looking for confirmation that its pretty much plug and play for a 2012....don't really want to pay MB to program them but will if i have too

The pressure readings on the dash started in 2010 for US based cars. My first test drive when looking for a C63 was a 2010 model and it had it. Then I bought the 2009 P030 car and it doesn't. AFAIK there is no way to switch without replacing lots of the COMMAND system with 2010 components.

realjones88

The Schrader 28214 definitely works, but they also $60 each (still cheaper than OEM).


They are plug and play. If I remember correctly the car detected them after a short drive.

jptaylor

if you pull up the link to the ones i posted above you will see it has SEVERAL part numbers, both OEM and aftermarket...do your eBay/Amazon search with those and you will find hundreds of listings...i had it backwards, mine were $54 not $45.

there is no relearn programming necessary for any w204, have them installed and drive off.

And why would Comand have anything to do with the pressure readings? Just as i said above, when i put my FL cluster in my PFL car it displays the individual tire pressures. the programming is in the cluster itself.

I bought these last year, and they worked 100% out of the box w/ my W204:

Polish-C63

Thanks for all the info guys, do you by any chance have the OEM part number for TPS for a 2012 c63. Or is the one you listed the OEM one?

Polish-C63

Perfect, may i ask what year is your w204?

jptaylor

the ones in his ebay link above are the same as mine and are for all years w204, so they are a direct fit for your car

Polish-C63

Thanks again, glad to see they are reasonable priced and plug and play...good stuff

My 2012 does not have sensors. It must be part of the P31/APX package.

604 C63

Oh, thats interesting.
You dont have TPMS at all? Just goes off wheel speed sensors like PFL?
Im surprised by that. Makes me wonder what would happen if I ran sensorless.

Alex.currie44

I asked that question of a contact I have at MBC when contemplating buying wheels for my winters.
The answer was I could run without them but the warning would keep popping up constantly because our Canuck cars are set up so you cannot disable the system. My contact knows me too well. "It will drive you crazy Alex! Buy them."
They were $69 as I recall at 1010Tire.
Interesting that
I had the winters in the car when I took them up to have them put on and the summers in the car on the way home and no alarms which means the winters were communicating with the car. Keep in mind it is the rotational action that turns them on in the wheels so I find myself wondering if they were on the floor of the car why they would be on?
That makes me wonder if our friend got the correct ones. The guy at 1010 very specific in getting my VIN before he put them on order.
Another explanation is there was enough motion to turn the ones on the floor on with the ones in the wheels an two signals confused the system.
Otherwise maybe I am confused.

LOLLLLLLLLLLLLLLLLL no wonder I had so many issues with my eBay sensors when I first put them in and I still have one go out from time to time randomly. I have had all 4 old sensors with dying battery in my trunk for like the last 6 months.

Vladds

There is an option code for TPMS low-entry level, which doesn't display individual pressure and TPMS med-high that displays.
My 2010 does display the individual pressures.
Although there could be an aftermarket that works on all cars, I would not be surprised if the factory part numbers for TPMS sensors would vary, depending on which of the options you have.

604 C63

See OP? You did OK

Mort

No TPMS sensors at all on my car. Just works off the speed sensors and ABS as you said.

If you go without sensors you will get warnings on the dash all the time. Kind of a pain and I am just as happy without the hassle of having to have them.

JimGnitecki

JPTaylor, I had a MUCH more embarrassing situation some years back. I had just had a car's ECM retuned, and on the ride home started to hear a periodic "beep" - the kind of beep that seems to be saying "Hey, something is wrong here."

I panicked and started heading back towards the tuning shop, wondering what the heck the problem was, especially since I had never heard a car beeping quite the same way!

Then, while waiting at a light, I tried to isolate where exactly the beep was coming from. Turned out, it was my cellphone, in the console, telling me that it was just about out of power . . .

Fortunately for what remained of my dignity, I was still minutes from the tuning shop, so they never found out about it . . .

In my experience very few Canuck cars come with TPMS. We typically get the warning when the wheel speed sensors detect a low pressure situation.
This is the first car that came with TPMS standard although I guess you could order them.
I find either way I seldom get a warning because I check them monthly. Now a puncture would be a different kettle of fish.

^ This.

Alex - I am afraid the OP is confused, not you.

The discrete TPMS sensors are designed to wake up and start transmitting via centrifugal force once the wheels rotate at a certain speed, and then go back to sleep (become inactive) when the wheels are not rotating. Furthermore, the Mercedes sensor transmission range and corresponding receivers in the car are positioned in such a way that only the nearest receiver will pick up the signal from the sensor in the nearest wheel - otherwise you would have no way of knowing what sensor is located at which corner of the car and thus what tire pressure corresponds to what wheel. This makes it easy to swap or even rotate wheels - unlike on Porsches for example, where the sensor numbers have to be programmed into the system so that the car knows what sensor is at what corner.

And yes, even vehicles of the same make and model sometimes use different coding, so they do need to be matched to the VIN. Working TPMS sensors from a US PFL C63 did not work in my Canadian FL car, but the sensors themselves were definitely OK as I gave them to someone else and they work with his car (also US PFL C63).

Brand new sensors always take a longer time to be initially identified by the car, so I suspect that is what happened when the OP put in the new sensors in the wheels, not that the car was picking up signals from the old ones.

Canadian W204 C63 cars with the APX / 507 package (forged engine internals) have the discrete TPMS sensors. The regular Canadian C63s use the ABS sensors to detect when a wheel is deflated and turning faster than the rest.
