Howdy and happy Memorial Day
I recently acquired an 07 4.8 X5 and wanted to ask about a couple issues.
130K miles and zero maintenance history (I know I know). It actually is clean and runs very well.
Seems to idle a tad high and rough for the first minute then is nice and smooth.
Also, occasionally it does a harsh shift, mostly when not in sport mode.
Having no history I decided to do new plugs and I got a great deal on a Bosch MAFS so doing that as well. When I started removing all the airbox parts I noticed this hard plastic hose staring up at me like a giant worm I disturbed. It's in the front driver's side of the engine bay, and I don't see what it's supposed to connect to. Can't find anything like it in RealOEM except for something on the fuel supply page, called a "scavenge air line."
Anyone know where this hooks up?
With regards to shifting, is there a DME update that might correct for this?
Thanks for any help.
Kevin
