Hi,
Im new to this forum here. Have bought a 2013 S85 with 150k miles about 6 months ago.
Since then put 11k miles on it
So far have replaced
- Brakes (warped front rotors and squeak)
- Tires (I suspect because of air susp leak rear of the car went lower then needed and chewed up the inside of the rear tires, negative camber)
- Headlights (bulbs)
Now, why I'm posting this here.
Since we got the car we had the red suspension message pop up and disapper randomly, I could also hear the "blow off" (compressor discharge ) sound when sitting at lights occasionally.
Recently the red alert came again and my compressor stopped working. It was 19F and we were away from home, so we had to drive. Back of the car sagged almost to the ground, front held up for a while, but by the end of the trip was the same, but we made it.
I pulled the tub and found the common "tee" leak at the Schrader valve tee (to manually fill the tank) that I fixed.
Then I checked for power at the relay (12v hot) and it has power so big fuse is good, 25A (f36) is good too, relay has good impedance (80ohm) so I assume it working, can swap but I don't think it's the problem. I don't think relay gets the power to energize compressor and it's the SAS that doesn't do it, also the solenoid block is not energizing either. I shorted power to comp with a clip and compressor started running, so it works and not seized. (That proves that all fuses are good too)
I manually inflated the tank (through the valve) and even with compressor running (manually) the car DOES NOT LIFT. I pressed different heights but it just sits there and no lift, even with full air tank.....
Car is bottomed out now, almost sitting on the floor.
Last thing left to check is a solenoid (valves) block, I might need to manually run power there....but it's cold as rats here in IL today...and I don't have a garage to work in. (I do have friends garage, but can't drive the car due to it being so low)
Do I need one of the rangers to reset the compressor for me since?
I wish someone would have a working copy of the Toolbox, this should be a very quick procedure.
What do Rangers charge? (I have never taken it to SC or Rangers, done all work myself, I'm obviously out of warranty)
