Not a great way to present the scan data,, can you please just copy and paste the text file?

 

According to the ross-tech thread I linked, that shutoff code is the HVAC unit being asked to inhibit cooling by the engine control unit. Unfortunately, it isn't immediately obvious to me why this might be happening.

 

Well worth repairing/replacing the outside temperature sensor though, since that is one of the inputs that the HVAC module uses to work out how to control temperatures in the cabin.

 

I wouldn't worry about the internal control module error, I think that is common and unimportant.

Hey @Breezy_Pete, sorry for the messy images. I don’t seem to find the text file of the scan, however I can go ahead and type the data that is in those images for ease of access for everyone.

 

Before cooling stops

 

coolant fan stage 1 ON

coolant fan stage 2 OFF

compressor load 85%

comprossor shut off 0.0

refrigerant pressure G65 12.6 bar

 

After cooling stops

 

coolant fan stage 1 ON

coolant fan stage 2 OFF

compressor load 0%

comprossor shut off 12.0

refrigerant pressure G65 7.4 bar

 

Can the outside temperature sensor wiring cut off be the reason for EcU to give the shutdown signal to compressor?

 

what else will I have to check to pin point the error if this doesn’t work(I ask because this error was not there earlier but the problem of AC still persisted. I suspect this to be a new error arising out of rat bites from when my car was parked at the technician)

 

please help me @Breezy_Pete,thank. I am very grateful

 

Hey @Breezy_Pete, as suggested by you I ignored the control module error and went ahead and fixed the wiring for the outside temperature sensor and the problem still persists. I was reading somewhere that the compressor needs to be calibrated or that an adaption must be selected after a compressor change to tune the ECU and compressor. Will I have to do this?

Can that be the problem? How do I proceed from here? please help. Thanks

Yes, I've heard of some procedure that is supposed to be done after new compressor installation.

I don't have any experience or knowledge about it, sorry.

 

I don't have any other ideas at this time; maybe someone else can help.

@Breezy_Pete oh okay, thank you so much for your guidance. 
This car has become super annoying suddenly. 

Whats the update guys?
