Hi, im hoping someone can point me in the right direction here. My F07 was sagging at the rear, I've just replaced the airbags and also replaced the compressor seals. The car self levels, and will stay this way, though slightly lower on right side. When driving and I put some load on the right side it seems to collapse and the left side raises to its maximum. It will not settle again until I crack open the air tube manually. Could it be the self level sensors, solenoid valve? Anyway to fully reset the heights, I have a OTP11 box. Note, before changing the airbags, right side was slightly worse but both would go down after a few hours. Thanks in advance for your feedback.
