New CSL wheels installed -Tire Light On

jsoltan · 03-09-2009, 07:17 PM

I just installed a new set of CSL wheels, reset the tire light and drove off on the maiden voyage. Within a mile or two the tire inflation light started blinking and then came on solid. I have owned BMW's and Mini's and have swapped wheels from OEM to track only wheels and after resetting the light it normally goes out. Do I have to take the TPMS from the stock wheels and install in the aftermarket wheels? Dumb ass question so be gentle!

Yep. Its a 'monitoring' system. If there are no sensors, inherently the car thinks all the tires are flat!! Another set of TPMS are typically around 250-300.

So I should take the snows off the OEM wheels, take the TPMS off and then reinstall in new CSL set? Why only on my MCoupe when I have changed many wheels off of earlier Minis and BMW's and only reset the tire inflation light.

Apparently the old systems based the warning on the rotation of the tires, i.e. low pressure results in a small diameter and faster rotation. The new system actually uses a sensor mounted as part of the valve stem. I believe its the 07 and newer Z4s that have the actual sensors in the wheel. I would prefer the old system so I don't have to drive around all summer with the tire light on but I'm not paying for a new set of TPMS sensors

yes, 07 and later require removal or doing something like the folks on club lexus did:

One thing about the Ricers is that they are very ingenious.

Wow...that's rather ingenious, actually. Even though I check the pressures constantly, I kinda like the piece of mind of the TPMS "idiot" light.

That being said, I even picked up a used set of TPMS units just for my track wheels. I got all 4 units for only $100 total from a board member so I know deals are to be found.

Wow, this is a lame. What a stupid design by BMW.

It's not BMW's fault. They're just complying with the new regulations. Europeans Z4's don't use the same TPMS.

JamesinIT · 03-10-2009, 08:18 PM

yes, I had to do the TPMS swap with my 07 Lexus and my wife 07 TL. Dismount pull sensor, put on new rim, mount tire. good to go.

jragan · 03-10-2009, 10:20 PM

Just so we're all clear, this regulation exists in the US due to the increase in popularity of Run-Flat tires. For safety-sake, it's important to know that your tires are flat before you go speeding down the highway at 90MPH and lose control...

Well the Z4M's don't have Run flats, IIRC. In which case it's just a feature, that i'd rather not have. They changed the power steering from Z4 to Z4M, so why can't they remove the need for these sensors? What help is it if you have regular tires and these sensors is what I am driving at I suppose.

Oh well, I guess it is what it is. Still disappointing and just made it a lot less motivating for me to buy a summer set of wheels and tires soon.

I have had the warning light on now for the second day and I find it a little distracting. I will look for a second set of TPMS sensors on the forums or Ebay. Not realizing this was stupid on my part.

Whether it comes with run flats or not, someone could put on run flats.

Yes, exactly.

**********s sells a set but its close to 325$ US for a new set.

Previous implementations of TPMS prior to 2007 I believe did not have a sensor in the wheel, but instead relied on the ABS sensor and the number of tire rotations to determine if there was pressure loss from a tire. The light could be easily cleared by holding the (!) button down for a few seconds in these systems.
