Ouch.

I imagine the torque converter lock-up is slipping due to inadequate pressure from the internal oil pump, especially since oil viscosity becomes thinner as it warms up. But I don't know why, or have proof of this.

I’m not 100% but I think the TCC is full lock up almost immediately in 1st, and stays locked through all gears. Do you have Carly or something comparable? You should be able to see tcc pwm data or a % tcc request. Watch/log what it does when you experience the hesitation.

And still no codes at all?

Any update on this x5?

We were on the highway last month, got rear ended. Car was totalled. Ended up being a blessing in disguise. Took payout and bought a 2020 X3 with 20k miles.

Sadly, while I absolutely adore my 2011 X5d and would hate to lose it, this is realistically the only way I could replace it semi-economically. I don't even know what I want or would look for. Probably another diesel even though diesel has skyrocketed to about 30% more than even premium gasoline when it used to be just a few cents more than low-grade around here. A Porsche Cayenne looks cool and for some reason the Jaguar F-PACE, too. Wouldn't mind another X5, of course.

Sorry to hear that! Not the “ending” I expected. Enjoy the new ride. My buddy has one and they absolutely love it.
