Nice looking e53!
What does the 'modified temp gauge buffer' do for you?
Are you able to set the temp for the over temp alarm or is it a predetermined bit?

Facebook Marketplace -- on 1/4/2022, see 2 X5's (e53) - with ** MANUAL Trans ** [1 in Charlotte, 1 in Savannah]

above link, may not work; how it pulled up for me.

PS: I'm Auburn '82 Finance grad, own / DD = 02 e53 X5 3.0i w/ 288k, all Maint & Records, runs great

Me: looking for e53 w/ Rear Air suspension (I kno, many/most, delete it out, for Springs) -- I want more Comfort, than my non-Air. I don't know if 3.0i e53's even offered < Adaptive Suspension > ... maybe in 'Sport Option'.

Likely: hunt for "high-Hwy Mileage" used X7 ... wish were more Used 7's around.
