I bought a set of extra wheels and bought the specified TPMS from Tire Rack......well they are not working. whats the trick to get the system to pick up the new sensors? The light is annoying.

You didn't mention setting them up on the in-dash menu. You did, didn't you?

98woody

I went through the menu to "use new pressures" but thats all I saw. Is there something else to do?

I think you need the star programer to have the ecu 'learn' the new sensors... don't think you can do the indash reset

98woody

what is a star programmer?

VaderSS

sorry... its what we used to call the current diag/program tool for mercedes.

I thought MB runs a self-learning or wake-up program that will reprogram the new sensors

VaderSS

tanktube67... good question. You would think so but i'm pretty sure. had to send a CLS over to the stealer last week (i know its not the same model) but it does run most of the same cam stuff.

Anyone else know? Now i'm second guessing?

When I installed my C63 wheels last year, I purchased a new set of sensor from MB and I had no problem what so ever.

VaderSS

tanktube67... thats what i'm saying... you bought them from MB not tirerack. I bought the ones for the CLS from tirerack

This is how the "new" TPMS system from Siemens should work. With the previous design from BERU, a reset from the cluster was necessary after a change of wheels (sensors).

The Siemens system actually even detects if tyres are inflated and sets a new reference pressure value automatically. Initialising the system from the cluster does not harm in any case but is actually essential only if tyre pressures are reduced (intentionally).

Some sensors were put on stock in a mode that needs specific driving to get the sensors wake up for normal operation. I don't even remember what the case exactly was and what was the exact wake-up procedure.

If the system does not start working after some good driving, it sounds like the sensors are not correct.

My new wheels and mounted tires from Tire Rack came with new sensors in place. After some brief driving, they learned and reported correctly. I suggest you contact Tire Rack.

98woody

Yeah I set the in dash to accept new tire pressures and after some driving the light is on saying it is inoperable. When I shut the car off and do it all over again its the same crap. From my point Tire rack 1) owes me a set of sensors that work and 2) the money to mount and balance AGAIN! This is bull**** in my opinion that they would sell something that isnt compatible. I hate to take ity to the dealer and add more money to the tab to find out tire rack ripped me off.

RLE

I don't think so.

One of mine was replaced after the dealer's tire mounter snapped it off and a simple dash menu reset was all it took.

Plus I bought a complete set for my winter wheels and a reset took care of it.

RLE

Calm yourself. Unless your dealer is one of those New Jersey places, I'm sure you could stop by and ask their advice.

98woody

Yeah, a 50 mile ride and a 1/2 day off from work. I am more pissed off at Tire Rack for not being honest.

I too had a set of new wheels, tires, and sensors from Tire Rack for our car, and the sensors were instantly recognized by the system, with NO intervention on my part whatsoever.

I would suggest calling TireRack and see what they have to say. I believe our sensors were from Schrader, but I wouldn't swear by that, and the invoice is in the car, three floors below me in the condo garage.

I expected to have to, at a minimum, reset the system, but in my case I needed to do nothing at all to have them recognized.

Woody- Tire Rack is a first class outfit with extraordinary customer service. As suggested, why don't you simply call them before you decide that they are in business to screw you.

98woody

I will Tuesday, I figure they are closed because of the holiday. The part that really pisses me off is even if they send me another set of sensors they wont give me the money for the mount and balance all over again.

Before declaring defeat, nicely/gently explain the problem to them and your concern. Your anger may defeat you more than anything else. If they have one of their authorized installers in your area, ask if you can take the car there for the fix at no cost, IF THE PROBLEM IS THEIR SENSORS.

FrankW

how "little" is involved in your "after driving a little"?

98woody

10 miles or so
Tire rack said I need to use the TPMS reset mode. It should be in the owners manual. But I cant find a thing. Anyone know how to do this???

Ron Jr

I hac no problem when I purchased my wheels frm Tire Rack. The sensors were mounted and the car recognized them right away. Their customer service is top notch when some vandal snapped one of my sensore they sent a new one right away (I paid for it of course).

FrankW

reset it a few time and drive a little more. if that still don't work then have them exchange it.

Strange you see nothing in your owners manual, I just went out and grabbed mine out of the trunk, checked the index and found all what one needs on page 273 of the manual.

I was actually surprised considering I have a Canadian model C350 and we don't have TPMS sensors, but the manual tells me exactly how to set it up

if you cannot find it, I will type it up for you as I see it in the manual

Cheers
