I'm asking for opinions about the need to change the transmission and differential fluids on a low mileage (22,000) 2011 335ix (E92) that is running fine, i.e. no problems. I can afford the work, but don't want to waste money.
Yes, be safe. The car is seven years old.
No, pouring money down the drain. Follow BMW change advice and wait (60K).
Too early for the differentials, change tranny at 30K if you feel you must.
At 60-80K, change both.
I did my MT & diff at 65k. Diff was clear and the MT fluid was darker but not super dirty.
Regarding my post of 8/2 (Thu), I no longer need an opinion re frequency of fluid changes.
On the morning of 8/8 (Wed), my Son called me frantically. "My house is on fire; get over there right away." The fifteen minute trip took ten minutes. As I turned into his street, five fire engines greeted me. In my haste, I ran over one of the fire hose couplings.
The good news - just a little smoke damage to the house, undergoing renovations, caused by cleaning rags in a trash can. The bad news - I ripped open my automatic transmission pan. Fortunately, I stopped immediately and caused no internal damage. $1,647 for a new pan.
Let the roast begin. I deserve it.

Grasshopper, you are forgiven.
