just recieved a 2005 vdp 153 k miles 1 problem i have is an air suspension error----and i think car is to high---have a new car scanner ---it says resivor plausibility error --please help

 

It may help if you you tell us what fault codes you have got back from the scan and any history of the fault on the car as you bought the car with the fault did the previous owner try to rectify the fault this may help with a diagnosis

 

forgot to get the # of the code----will do it monday ---but i have tried another wabco ecu box thats behind the seat and unpluged the 2 manifold plugs to no avail

 

Reservoir plausibility error is C2303, and you can measure the ride heights from the fender (wing) arch to the wheel center to see if it is actually too high. Front spec is 371 to 401mm, rear spec is 358 to 388mm. I just measure to the middle of the cat's face.

 

thanks i will check the hight tonite

 

There is a calibration that can be done to calibrate the ride height. However, that code has been linked to the compressor failing, unless you have any other related codes logged. Try doing a calibration, which needs to be done using SDD and see if that helps, if not, the compressor for the air suspension is most likely starting to fail.

 

You might check to see if the ride height sensors and the link arms are intact.
Sometimes people change the ride height by altering the link arms or brackets??

Sometimes the link arms become detached.

well checked the hight and is within perameters given will try more what is this calabration procidure?----i also plan on making a test guage for the compressor -i think it needs to put out 300 psi-!!!

 

thanks for all the help here.but i found a thread (air suspension fault 2005 xj8l)these guys have the exact problem i have with a lot of good solutions

 

don't calibrate with a fault present, that code normally points to a tired compressor,


does the error light clear when you start the car? and if it comes on after 5-10 mins in every journey it is pointing to a tired compressor
