Hey guys,
I've got a plan in the works to get rid of my TPMS. The AMG performance package wheels that came on my car are off to the powder coating shop right now, and when I get them back I plan to have Hankook Ventus tires mounted, using standard rubber valve stems and giving up on the TPMS.
My car (2011 CLS63) doesn't give a constant air pressure value on the dash, it merely lets me know when one tire drops out of a certain range of the others. I still check my air pressure once a week, and believe me, when I get a flat on the road, I know it - so the TPMS is of very limited value.
Further to the plan, once I mount the new wheels/tires on the car, I plan to toss the old sensors in the trunk and reset the system according to the manual. Since all sensors will be reading the same (Atmospheric) pressure - I shouldn't get a warning light.
I figured that the back wheels were the same distance from the receiver as the boot, and 315mhz is a low enough freq that it travels through hard material a little better than a higher freq would.
If it turns out that I'm full of beans, I'll try your suggestion to reprogram.
I don't think your tires have sensors. If it is the same as my wife's car, it uses some of the electronics / ABS sensors etc to monitor rolling resistance or rotation (not sure how it really works). That is why you do not have a pressure display like a proper TPMS.
Yes with run flat indicator there are no sensors... If he does in fact have Tpms then the only way is to code it out the system. The sensors will not work in the boot!
You actualy have a tire pressure loss warning, which uses wheel speed sensors to tell if one tire has lost air to rotating at different speeds. There is no actual monitoring of pressures like a tpms system. Yours is a 2011 so Im curious as to why you have the tire pressure loss system vs the tpms? Are you the original owner of the vehicle?

Hey Tommi, Thanks for the response.
Yeah, mine is a 2011, but still a w219. Mercedes went to the w218 later in 2011, right after mine was built. Both cars are still a 2011 model year, but different models!
And I'm not the original owner, no. What makes figuring out these types of things even harder is that when I bought the car, it had no owner's manual...and the latest one I can find online is for a 2010, and IT was printed in 2009. So, I don't even know if the crap I get from my owner's manual is accurate for my car

I have access to Netstar where they publish digital owners manuals. I can try and upload if you want one. I also have access to VMI which should show which option you should have, unless previous owner coded that system out and had the tire pressure loss system entered into Vedoc? That would be interesting to see though. If you are interested you can pm me your vin and I can try and see what I can do.pm me, I can email you pdf of your owners manual.

There are quite a few aftermarket systems around. The previous owner may have had one that was not integrated into you car. i.e. sensors in the wheels with a separate display unit mounted on the dash - he may have not been bothered about the cost of removing the sensors!
Mounted the wheels on the car a couple days ago. No sensors on these wheels, none in the trunk
I drove it about 20 miles to see what kind of warning I'd get on the dash. I got nothing. Will let you guys know if anything changes, but right now - I'm happy that there're no issues...

OK, there are issues. Warning came on after a longer drive today.
Gonna toss the old sensors in the trunk to see what happens, even though I'm told it won't work. Will let you know, stay tuned!
The Merc is at the dealership now. I asked them to code the TPMS out of the system so the warning would go away. The service writer told me that they couldn't, by law, code that out. (Well, **** - there goes that idea)
Don't really feel like having the tires removed and more transmitters installed on the wheels. Other suggestions?
A resolution! Russell - your suggestion to have the sensors coded out was absolutely the correct answer in my case, I just couldn't find anyone to do it. Dealer wouldn't, Inde repair shop wouldn't... Finally, I was able to chat, in person with the mechanic that works on my car at my local Merc dealer. He understood what the problem was, and he (without saying anything to the service writer) coded out the TPMS so my light and waning would go away. He's my hero and I bought him lunch.
That's good, many things can be coded on or off, certain things can't be done at the dealer because scn coding is only an online option at the dealer, Daimler servers check the vin and automatically code the vehicle,
Luckily that technician could do it for you.
