Re: Possible Haldex Failure 2003 XC70

Find another garage for sure, this one does not have car mechanics understanding how mechanisms (trust bearings, hypoid gears) work.

Literally 4 bolts. Once the driveshaft is out, it is literally 4 bolts.

Re: 2006 XC70 A/C needs refrigerant

In the donor I bought for drivetrain and interior transplantation there was a hole in the condenser. Didn't have to evacuate anything, nothing left. Zero pressure. Just vacuum and fill. Need to evacuate as open to atmosphere means moisture and contaminants got in there which will kill a compressor....

Re: Help! Bricked CEM, possibly other modules

Also try to put into programming mode, pull the DiCE from OBD, close the tab/window, wait a few seconds, connect DiCE back.

Re: Help! Bricked CEM, possibly other modules

Flashing CEM does not rely on any other module. CEM reload is supposed to fix the problem, since Volvo HQ knows what needs to be in your CEM (car config) by your VIN.

Re: Vida CEM swapping

Okay, so I have resolved my borked CEM issue with VIDA basically by doing rain dances and offering prayers.

Re: Vida CEM swapping

PIN is not compared directly, rather a result of secret calculation with PIN as input argument. Is this a hash, or salt? SW asks CEM for seed, CEM sends 3 random bytes, SW combines them and 5 bytes of PIN into 8 bytes of input vector, performs hash computation and sends 3 bytes of computed key to C...

Re: What did you do to your P2 Volvo today?

Warm, dry day, after week of cold and rain, and before week of cold and rain. Sneaked under to check it is really the driveshaft that clicks under the console. It is... U-joint spew grease, vibration destroyed the rubber. Or vice versa. Anyways, I think I'll bite a bullet and get this Dorman drives...
