Picked up my car on Friday. Could not get TPMS to work - kept asking to be recalibrated, then recalibrated, but when tried to get reading, said needed to be recalibrated. Unfortunately, snow was on the way so I had to put winter wheels (OEM) + tires on -- used new tpms sensors and valves from tire rack. Immediately after installation, had same issue re recalibration. Then drove a few miles this weekend <20 and this morning got a message and warning light saying no sensors present.
Anybody have any ideas before I call dealer. I really don't want to take the car in within a couple of days of new.

I still can't find the TPMS info on my MFD. Can you shed some light on that?

When the system asked to be recalibrated you have to reset it. As I recall you call up the system and hit the reset button. The MB call center can walk you through the procedure if neccesary.

After recalibration you have to drive a long time before it will read the pressure - say 20 minutes on the highway. Around town with stop and go doesn't get a reading as far as I can tell - you have to have 20 min of continuous driving.

P.S. On my system the TPMS is on the same screen that shows the digital speedo. You just scroll up/down till you get to the TPMS and then hit the sub-menus.

corgiman is correct on how to find TPMS. My concern is that I drove the 20 minutes and it said couldn't find sensors.

I went through the same thing on my S500. I was told by the dealer that not only do you have to go through the gymnastics of the reset but the cold starting pressure has to be higher (by 3~5 psi) that what the spec calls for. I asked why and was told some BS about the sensors ability to read pressure after reset if the PSI is below a certain level. I'm running 32 all 4 now and have not had issues since. Hope this helps.

The dealer tried to charge me $58 for the reset and I REFUSED to pay it. I told them that I followed the proceedure in the manual and it didn't work. I asked how would any one know about this Rube Goldberg set up deal any way. Crystal Ball was not my best subject in school.

Our '02 S500 is doing the same thing. Do you have the Sport Package with AMG wheels? On of the tire pressure stickers on the car says 29PSI and the sensors seem to screw up at this low pressure. If we go by the other sticker which reads 34, we have fewer problems except for ride quality.

The rims are the standard 17" rims. I bought the car with 10K miles and the original owner had purchased AMG 2 spoke rims for the car when it was new. He kept the rims for a new '06 S500 he bought and but the new standard rims and tires back on the car. When I first got the car, I had the TPM errors because the car had to re-learn the original sensors. That's how I got into this. The sticker says 29 front and 32 rear. The dealer took all 4 to 35 and drove the car about 30 miles...then backed down to 32 psi. No more TPM problems. I thought about going back to original spec PSI but the ride and handling are ok so I'm sticking with it. I'll probably get a set of AMG 2 spoke 18" with new tires and TPMs but Christmas and Hurricane Wilma don't leave me with $3K to throw at new rims and tires right now. I've got about 13.5K miles on the car now with about 3500 on the tires and the car rides great.

I guess every time we change rims/tires we must go through this TPM reset deal.

But, are you guys getting the no wheel sensors found message with the idiot light on - or are you just not getting a reading. I suffer the former

E55AMG99

Never had the "no sensors" error.

Thanks for the info sprink49. I'll go out and try the pressures you suggested.

I don't get it... Why do some of us have TPMS on MY2006 and others (w/ MY2006)seem not to??? Seeing as it was not able to be ordered as an option. I go through the MFD and no TPMS, I've looked everywere including the submenues from the digital spedo screen, I seem to be having the same prob as Kev04C320; no TMPS in the MFD...I would welcome the recalibration issue at this point. If you bought a 06 E55 w/TPMS please chime in; did the car just come with it? or were you able to order it somehow? confustrating!

Kev04C320

I looked up and down, sideways, inside-out, and even backwards. I still can't find the menu of the TPMS. I'm putting on snows on Thrusday, so I'll see if I have sensors on my wheels.

On my 05, the TPMS menu is a sub-menu on the screen that begins with the digital speedo. I use the arrows from the speedo to get to the TPMS. Has anyone with an 06 found a screen that displays all 4 tire pressures at the same time? Mine does it all the time when the ignition is on. The car does not have to be driven, it just works, always, and it is fairly accurate. I ues ie it when I am adding air and then compare it to a dial indicator gauge. The both of them are close.

Kev04C320

I do not have that screen in my MFD last time I checked, which was yesterday

Can Drive 55

That is messed up. The TPMS is a great feature. I suppose it has/or will suffer the same demise as the solar cells, rest feature, distronic in non-AMG cars, driving dynamic in non-AMG cars, CLK 55AMG coupe, etc.

Kev, you should have a screen that gives the digital speedo. That is the "standard display." When you bring up the speedo, push the down arrow. What do you get? On mine, it's TPMS. I don't know what it would show if you don't have TPMS, but it might be the maintenance service indicator (miles to next service).

I thought all new cars since September 2005 were supposed to have them by law in the US?

Can Drive 55

I don't think the law requires a digital indicator, just a warning light or an audible alert when any of the tire's pressure is below minimum spec.

I see now

Corgiman is right (as usual). When I changed to snow tires I had a similar experience including not finding sensor warning. I kept resetting and reactivating the TPMS. Evnetually, I left it alone for a long time and it started working.

deaddog

Pbglas -- When you got the not finding sensor warning, HOW did you reset and reactivate? There appear to be NO instructions on how to do it. All I can get is the "Tire pressure monitor inoperative No wheel sensors" message. I cant pull up the reactiviate message or anything else. Pushing the reset knob does nothing. Any help appreciated

Pbglas

I don't remember exactly. I might have just hit the reset button or gone to check if it was seen as a 'malfunction' (in the malfunction screen), returned to the TPMS display and hit the reset button. The main thing is that no matter what you need to wait a long time before it reads the tire sensors.

Even after it started working it stopped working. Ultimately it worked continuously.

By any chance, do you have a fifth tire with TPMS in your car? If so, get it out before TPMS will work.

Good luck.

When I put snows on, the TPMS registered immediately. I didn't have to reset or anything. It's like the system didn't know the wheels and sensors had been changed.

Sorry if I am posting off topic but it seemed to be better to post here then start a new thread on basically the same thing.>>> I just got of the phone with Merc Tech support. The lady assured me that my 2006 E55 should have come standard with TPMS. She said if I can't access it that I should swing by my service department and get confirmation of their existence or not. She said if they are not there; to call back and a remeady will be made, as the 2006 E55 is deffinatly being advertised with TPMS as standard.
So I still pose the question here,,,if you have a 2006 with TPMS,,,how did you get it???
Can you tell me deaddog? Did you order it, or did it just come standard???

Can Drive 55

I checked the MBUSA web site for E55 specifications. The following was copied (The "1" after "tire pressure" was a small superscript for the footnote as indicated)

• Multifunction display in the center of the speedometer can be scrolled via steering-wheel controls to operate and display various menus and vehicle features including the resettable trip meter and outside temperature indicator, digital speedometer, Maintenance System, tire pressure1 and ……

1. When equipped with this option

So, the website calls it an option, but that could be their wording and in reality, it comes only on the E55 and not non-AMG cars, thus making it an option, so to speak. It is not listed in the options section. One thought that I have - it is not referred to as "Tire Pressure Monitoring System" as it was in 2005. there could be some light and ringy dingy somewhere that warns the driver when a tire is low, without specifying which one. Interesting, to say the least. The one thing that we have learned is, nobody who works for MB, not even the woman at tech support, knows much about it. Figures.

And the saga continues. I predict that one of you will be persistent enough to find out what the facts are and will let the rest of us know. I am sure that info will not come from an MB dealership and certainly not a salesperson.
