All the details are there
I was able to pull up my test six today and e 70 works very differently from e 53.
The tank appears to be more like the sedans where both sides are similar in size vs. left being much bigger, also i need to look into it but it seems like no pump well which is definitely a downgrade.

5.4 left 31.6 right. I would say almost for sure you have a transfer pump problem. i’m very close to empty on the left side. I will drive enough today. That should be zero and then I can see if all the fuel stays on the right side after the transition point.
