Excuse me,
Since we disassembled the automobile, I've been dealing with this issue. Prior to it, the vehicle drove flawlessly straight and true, without any balancing problems whatsoever.
The U0155-87 error code was the most prominent of many issues that surfaced following the split. Once we were able to rebalance the car, the inaccuracy went away, but it's still not entirely level. The right side of the back of the vehicle is elevated above the remainder of the vehicle, and the back of the vehicle appears lifted in comparison to the front.
There is a constant whistling sound when I'm travelling at high speeds. The ride is fairly harsh, and the back end is incredibly springy. From time to time, I'll notice that the automobile is sitting with one side entirely raised and the other side totally dropped.
My previous attempts:
Depleting the air reservoir. Compressor replacement. Struggling to adjust the level (very difficult right now)
I would be eternally grateful for any insight you can provide as to the nature of the issue, its probable origins, or your own personal experience with a comparable situation. Fixing this has been an absolute nightmare.
Much obliged.
