Can someone here give me a definitive answer as to what needs to be repaired or replaced to remedy an intermittent sinking right rear corner in the ABC system. I also occasionally have the rear sink after say 4 days of not driving, but I understand this is normal (is it?).

Finally, the car will run fine initially, then after about half an hour, turn on the "ABC see workshop" warning. No change in level, ride or anything else, but this is consistently happening every day I drive the car more than half an hour....

I love the car, but this is extremely annoying! Heeeeelp.....!

 

Look under the car and check to see if the ABC Strut is leaking. If it is then I would get it taken care of ASAP. The harder the ABC pump has to work, the faster it breaks... ABC repairs arent cheap. It is normal for the car to sit lower after a few days.
