TPMS sensors?

[IEDEI]

Anyone selling any? or KNOW which type we need? Any links or insight into where i should buy these?

From what i've found, we need the 2010+ TPMS sensors right? I'd like a set to get installed on my winter wheels setup.

Not exactly the info you were looking for, but in my case, I just coded the TPMS out when I got a 2nd set of wheels/tires. When TPMS is coded out the system defaults to the RDC system (rolling diameter calculation). So I get the best of both worlds, no light on my dash, no sensors to buy, but I still maintain the safety system.

well last winter i ran no TPMS in the winter on my 135is, but it sucked because when i had a slow leaking flat tire happen to me i hadn't been checking the tires constantly. So this time i'd like to have TPMS installed......

I assume you simply installed tires with no sensors, but didn't recode the car, right? Re-coding the computer would have enabled RDC and would have caught that.

ah interesting. yeah i just put on the tires and let the warning sit around all winter. i didn't even know there is a backup RDC

Nice--I just learned something very useful!

anyone with info on where to get the sensors?

thanks!

Dealer or Tire Rack.

Some board sponsors also sell OE brand sensors: http://www.1addicts.com/forums/showthread.php?t=338026

IEDEI > I just got my sensors a few days ago. I was lost in space when I started looking. I went to T P M S.com -- problem solved.

Is coding out the TPMS and easy do?

This should definetly be a sticky! I just bought a winter set of rims and was debating whether to get sensors or run without. Now I know to run RDC , but the question is this something an owner can do or is it still a shop function.

Interesting - I thought I had TPMS so I bought a set, only to realize the car will do RDC and not complain (because I ended up didn't installing TPMS). This is a "stock" 1M that had tires changed from PS2 to PSS before I acquired - I would be surprised if the dealer "coded" that out and not have a warning without TPMS

Canadian 1Ms don't have TPMS. I had the same problem. I bought mine from someone in Canada that had changed tires. My US 1M had them, so when I realized they weren't there, I had the same thought. But, Canadian 1Ms don't get them. They use the wheel speed sensor to detect rotational difference when one tire is going flat. You fill all four tires to the same pressure then zero out the tire sensor using the stock. It will then set that rotation circumference as the fully inflated one.

So with a Canadian 1M, the computer won't bother with the actual TPMS - which means they work better staggered at the same pressure. I guess with a square setup and different pressure, RDC probably won't work anyway?

I wonder if you can code the car to actually use TPMS

I actually like not having TPMS because I can change wheels without worrying and I have seen the Canadian system work pretty well. When I bought the car and was driving cross country from Toronto to San Diego, the light came on due to pressure differences. But if I only had one set of wheels, it would be nice to have. There is probably an RF receiver somewhere that is needed and I doubt they would include it with the non TPMS cars unless it was integrated with something else, but I also would love to know this too.

I looked at a couple of threads but they all say different things. In 2011 it appears they switched to a single RF receiver either near the shifter, under the right side of the car near the footwell or in the right rear wheel well?????

Anyway, If you bought the RF receiver and had the connector, you can probably code and turn it on but that is just an educated guess.

[CP 1///M]

Oh well I never bought the RF receivers - I just bought the TPMS on the assumptions that they do have TPMS, only to find out that they don't need them. I still haven't removed the tires from the stock staggered wheels since I took ownership but car never complained about lack of TPMS
