Tire Pressure Sensor recommendations

[enuff_zed]

My car takes the sensors. That is not in question. I guess I picked the wrong forum to ask.

OK, no need to be funny about it. You asked and we all answered to the best of our knowledge.
To further that knowledge I would appreciate it if you are able to find out where the receiver is mounted and pass that on for future reference.

I don't know, it's a learning experience for all of us. I for one honestly thought my E85 did have TPMS, and now I know it doesn't.

Your car does have TPMS - all E85s have it because BMW sold them with run-flat tyres as standard so it was essential. But UK cars all used wheel speed sensors to monitor it.

Ah, yeah, sorry, I meant via sensors in the wheels. I should have elaborated that.

To keep my fellow pedants happy, the system on the E85 is actually described as a Run Flat Indicator.
At least, on UK models

I thought it was called FTMS without wheel sensors (flat tyre monitoring system) or TPMS with wheel sensors (tyre pressure monitoring system).

I was also under the impression (could be wrong) that cars with i-drive generally have TPMS but cars without have FTMS. And that cars with i-drive could have either, but without can only have FTMS, as the basic computer on the BC stalk can't work TPMS. In the UK.

I just went and opened up the manual. That’s what it said in there.

That may be what it was called on your facelift E89s, but as Martin said it's Run Flat Indicator in the handbook for my 2006 E86 (and 2005 E90). And i-drive wasn't an option on E85/86s!

I believe the aftermarket ones are fine...

[Z4LauncherMan]

Also want to say I have aftermarket ones in a different vehicle and they work great.

Whatever they want to call them, tyre pressure monitoring is more trouble than it's worth IME. I have forgotten the amount of times I have been driving down a motorway (usually in the rain) and a car (any car) has decided the tyre pressures are wrong. Then pulling over in the rain to check them (just in case) and one is 1/4 of a psi different.

It's always a learning experience for me. I just learned that the valve stems come in significantly different lengths. That makes perfect sense but it was something I hadn't considered. The 108 wheel takes a stem 55mm in length by my cheap dial calipers.

I am considering Huf as the replacement sensor. I just need to make sure the stem included is the right length. I don't want to re-use stems that are 18 years old.

Just to follow up, I went with the HUF sensors from TPMS.com. They arrived quickly and with the correct "long" stems. The company rep was a pleasure to deal with over the phone.

The sensors did not need set by a tire shop. After driving it for a little bit, the light went out on its own. They seem to work just fine.
