Thanks Ed, yea I narrowed it down to a bushing and the “advisor” at Harper Infiniti said it may be years before I have to replace.. if I notice irregularities in tire wear or difficulty getting alignment, then it may be time to replace.. so far so good..
As for the oil consumption pre 150mph and post 150mph there was zero to unnoticeable change in levels. I recently switched from Royal Purple to Mobil 1 0w-30 since is carries Mercedes 229. And BMW LL-4 certificates to use for 10-15k intervals. Also the Long Life Mobil oil filter. I am at the 9500-10k area now and have added 1 quart in the 10k. So.. looking pretty good.. the Mobil 1 is the one that says it is low sulfur and EASY on catalyst.
I thought about your observation on the suspension and decided to read the entire section in the FSM, I don’t know if other models without adaptive suspension do anything, but the 2005 was ONLY availible in one variant and the active suspension was standard.. I digress, at 60mph the computer places the suspension in “sport” automatically without alerting the instrument cluster light. Also the self diagnosis function for the active suspension has finally proven to me that the suspension does anything at all since it’s hard to notice the difference in either setting....
Yes the Q has found a place in my heart... I had the resonator removed along with the electromechanical “flap” in the “active muffler” and put a Magnaflow muffler on and just wow.. Zero droan, and I would compare the sound to a few of the M power BMW’s or maybe the late 80’s early 90’s last Toyota Supra. Sounds great.. you know your in the presence of a V-8 but not a “redneck” lol...
