Getting the ABC WARNING!

After about 30 minutes of driving I am getting the Visit workshop message and about once a week I get the red ABC warning. When the warning is red the car will not raise up and rides bouncy. I can turn the car off for a couple of hours and it goes away, the suspension does not drop down even if sitting for a week.Any help appreciated.

Uh, I took mine to the dealer when this happened. 4 days later I got it back, and it was .... $4k. Luckily the extended warranty I got covered it 100%.

Yea sorry to be the bearer of bad news but your ABC pump is at the end of it's life. It is only able to build up enough pressure while it's cold. This same thing happened to my car as well. The longer you wait the worse it will get for the entire ABC system. A failed pump can contaminate the fluid and kill the valve blocks.

2018 S63, lowered
Happened to me as well on both of my 65's.....pretty standard to have to replace these at some point during the life of the car- reason #73 I'll never drive one without a warranty. I think I had to replace 2 of them on my 220.

Good luck and hopefully it's something else.

Yeah I was gonna purchase warranty when I purchased it but it was an additional $12,000. No one will warranty it now! Gonna take it to the dealership Saturday, just weary of all the stories about the dealership overcharging

A day late and a dollar short. You need a new pump.
