HVAC: Consolidated Compressor Fault(s)


Supporting Member
Sep 8, 2013
I had my roadster in the shop a few weeks ago for a noisy AC compressor. Casey at the Denver Service Center unbent a hose and wrapped some insulation around it, which mostly got rid of the noise. Today I was charging up before leaving and got HVAC: Consolidated Compressor Fault(s) ID:1428 Data:0x30000000. The car is still drivable. I have an appointment next week. Could this just be the AC compressor? If so, does anyone have a ballpark on the cost? I know a BMW compressor is at least $300 and 6 hours of labor. Is it an off-the-shelf part and maybe something I could replace myself?

Everyone seems to complain about how bad the AC is on hot days, but mine seems plenty cold. I could definitely tell when it was diverted, but that never lasted longer than a minute or two on the few upper 90 degree days we've had. I don't use it much below that.

1.5 compressor:

PolyVinylEther compressor (PVE lubrication oil)
non servicable rotary/rolling piston type pump
250-400V (AC)
20-80% PWM
8A max. current
6500 rpm max.
blue color item, located deep down under front hood belov the DC/DC converter

2.0/2.5 compressor
Poloyester Oil Compressor (POE)
400V (AC)
metall color (smaller than the one in the 1.5; no seperate containment looking like a bucket)

Important: no mixing of PVE and POE oil types. When using a HVAC recovery machine be sure to purge before using different oil.
Receiver dryer should be exchanged when refilling or leckage avoiding contamination of the HVAC system.
