When you serviced the e53 6hp26 did the 2-1 bump issue go away straight away or did it take some time? I was wondering if the transmission will take a bit of driving to adapter to the new fluid and seals?
With XHP does it just download the software straight from your phone to the car? I have plugged it in and got it to read the my transmission and that all worked fine. It made a backup of my transmission then was able to see some wear values.

I actually serviced it twice to try and get a greater percentage of new fluid in there. I didn’t use genuine Lifeguard fluid as I’ve got a XR6 turbo with a ZF 6hp26 and used other fluids in that so knew it’d fine, I think the bump was gone pretty much immediately.
With XHP I wasn’t able to use my phone;
I used the same cable I use with NCS/ ISTA/ etc and a windows laptop.
I don’t know if XHP will fix your bump. I think you can see current adaptions in XHP but not reset them , as XHP doesn’t recommend it.
I flashed it without even a battery charger connected.
