Temp gauge

[phillymb75]

2006 X5 3.0 98k miles

Noticed my temp gauge isn't going above 25% under normal driving. I had it on the highway for two hours last week, it did go to 50% on an up hill stretch, but then went back down.

Is it just a gauge problem? I just had it in for service at BMW three weeks ago, what I thought was it's last free service (CPO and extended maint run out on 11/17)

I've had the car since 36k miles, only real repairs to the engine were two oil leaks, all other maintenance done by BMW by their standards... had other things fixed, so I definitely got my money out of the maint and cpo warranties.

Any other problems this could be indictative of? I'm running out of time to get things fixed for free, any comments would be appreciated. It goes in for service next week.
