Hi guys

Getting all of the following:

a. U0132-87 Lost communication with ride level control module
b. B1B74-00 Front foot-defrost mode stepper actuator
c. B1B75-00 Front foot-face mode stepper actuator
d. B1B76-00 Left front air blend stepper actuator
e. B1B77-00 Right front air blend stepper actuator
f. B1B78-84 System pressure
g. U0416-86 Invalid data sent from vehicle dynamics control module
h. C1A20-64 Pressure increases too slowly when filling reservoir
i. 0010-88 MS CAN communication bus
j. U0159-87 Lost communication with parking assist control module
k. U0127-87 Lost communication with TPM module
l. U0155-87 Lost communication with instrument cluster control module

First could any of these be related to a wiring connection issue, or instrument cluster dry-joint issue or something else?
Second is the suspension issue related to the rest or it is likely to be an issue with the compressor. Is it the compressor failing or over working as there is a leak? I don't have any noticeable droop at any corner of the car.

Any help would be gratefully received.

 

Not cluster as that will bring up other faults but i would say a wiring issue most likely, you also have an EAS compressor related error in "C1A20-64 Pressure increases too slowly when filling reservoir " which generally means the drier needs servicing.

 

Did you ever get this problem resolved? I have many of the same codes and my A/C unit went warm.
