Hi there, I have plenty of bizarre problems with my P1 2007 V50 T5 AWD.
I'm trying to diagnose a "anti-skid repair" message.
The day before I read the codes with VIDA, the car showed some other messages like "brake failure" and was in engine power reduction I guess limp mode.
I was able to read the codes and there was un bunch!
BCM-0094, 0097, 0100, 0115, E003;
ECM 142B, 710B, A20C, E003, 7300, 740B, 900C, 941D, 943B
EPS-E003
SWM-0A11, E003, 0A10
etc...
Seing all those codes, I have thoroughly verified all grounds and battery power.
I've also checked conductivity betwen DEM 4 pins connector and CEM. Everything semms ok. No ground fault or short circuit.

When I wanted to clear all codes and re-read, it was impossible to do the procedure (start the engine twice...) because the engine doesn't start while vida is connected.
If I unplug VIDA, I can start the engine and run the car but the awd is disabled.
All the messages disapear of the dash except anti-skid repair needed.

Any clue for that?
Why is the car returning in brake failure, immobiliser state and limp mode when vida is connected?

 

99% of cars my shop scans with VIDA - is with the engine running. Pull car in, leave engine on, plug in DICE, scan car. (don't want the battery to go dead during the scan process do we?)

Are you saying the engine stops when you plug in your DICE?

 

No the engine do not stops. I did scan with VIDA engine running. As soon as I plug Vida, the status on the dash messages changes for Immobiliser, brake failure, and engine power reduction.
