I went out to check my TCU for the Bluetooth pass code, and I didn't see any sort of label on the unit. Is the label underneath the TCU?

Thanks,

I'm not totally sure, but I think the Bluetooth code came along with the bundle such as the owner's manual and such. It's on a card that specifically has the Bluetooth information, and the saleman specifically told us not to lose it.

It should be on the top of the unit which is located behind the left access panel in the cargo area.

Here is a picture from my car: http://www.bimmerfest.com/forums/showpost.php?p=1389457&postcount=4

As AzNMpower32 said, you should also have received a card in the packet of literature with the code on it (it is a duplicate of the sticker on the TCU, I think).

Took the X3 into the shop to have a "service engine soon" diagnosed and to have my BMW Assist activated. Turns out there was a problem with the TCU (the one that didn't have a label!) so they replaced it. The new TCU does have a label :).

That was the problem - it didn't have a label! :rofl: That label is verry important to the operation of the TCU :D ;)

When we dropped the X3 off at the dealer, I made a comment to the effect that since the vehicle had such little gas in it while we were test driving (<20 miles worth!), the oxygen sensor may have picked up some gunk or become unhappy for who-knows-what reason. The service advisor assured me that this probably wasn't the case...

So when I got the vehicle back and looked up the service codes (SI B12 08 05 was one) guess what sensor was generating an error? Yep...the O2 sensor. A software update took care of the problem.

I ran into a somewhat similar situation with my Jeep Wrangler. After a couple of weeks of buying gas at the "cheap gas" place, my service engine light came on...I traced the error code back to the O2 sensor. Ran a couple of tanks of premium gas before switching back to regular (from another source), and the problem was solved.
