I
just got my car back from the shop, now the car is high
Unless
the tech that worked on your car saw the need to raise the car by adjusting the
sensors (to help get the alignment in specs), the problem may not even be the
techs fault.
If
the problem is "air suspension" related:
If
the "check suspension" message does appear after startup,
the module or "brain" is noticing a problem. If the "check
suspension" message comes on within 45 seconds of startup, you have a venting
problem. This is most likely a vent solenoid malfunction caused by moisture in
the system. Go HERE for an explanation
of what caused this problem and what to do about it.
If
the "check suspension" message does not appear after startup,
the module or "brain" isn't noticing a problem. This could be a disconnected
sensor or an adjustment is needed to bring the car to the same height it was previously.
The first thing I would do is to make
sure the sensors are still attached. If you have a disconnected sensor(s), the
module "may" keep the compressor on to try to raise the car up....not
knowing that the reason its not getting to the desired height is because the sensor
isn't connected. BLOWN AIR STRUTS/SPRINGS CAN RESULT.
If
the problem is "suspension" related:
When
the car is raised on a rack, the suspension will extend as far as the struts &
shocks will allow. When the car is lowered, if the suspension has a binding ball
joint or upper/lower control arm, it can keep the suspension from "relaxing"
and going back to normal height. This can be easily diagnosed by jouncing or pushing
down on the suspension. If you have a binding problem, it will be really hard
to push.
NOTE:
Believe
it or not (unless a sensor has been disconnected or has malfunctioned) if the
car was raised up with the susp. switch left on, the air suspension system will
simply vent all the air out
and lower the car to the bumpstops. Unless a malfunction of the system occurs,
the system won't be damaged!
