160,000 miles and the old girl is starting to complain. I have a knock in the right front end that I can't identify so far. Changed the axle assembly but no love, noise still there when backing out of the garage. One loud knock and then silent. Wheels turned as I drive away and 2 knocks and then silent again until turning sharp in parking lots. I had changed both lower arms before the sound started occurring so I double checked my work and nothing was left loose.
Today for no reason the dreaded 4x4 light and amber brake light lit up followed by the trans failsafe mode. Shut everything down and restarted it and all the lights went out and all good again.
I have also been fighting a P0172 and P0175 system too rich left and right bank so I am doing a smoke test in the morning to see if an intake leak is causing those codes.
I unbelievably pamper both my BMWs but the X seems to want a little attention lately...
