'Anti skid service required' help! V50 1.6D

[ajlongfield]

Hi all,

I purchased a Volvo V50 estate 59 plate 125k on the clock. Me and the family are in France for 6 months so needed a car to get us down here with plenty of space.

Had a few overnight stop offs on the way but 2hrs into the last 4hr stint I had the 'anti skid service required' message appear and the torque pulled from the engine on any incline.

I have been trying to research the issue and saw that the CEM connections could be faulty - I have had it out and cleaned it but still have the message. Thought this could be it as when I go onto the 'secret' DTSC menu the CEM just states 'Checking' - also when I quote wiggled the wires in the footwell it seemed to not come on immediately when I started the car

Also had an engine service light come up 30mins or so after the Anti skid message - immediately after I had re-fulled (not sure if this is linked?).

I have plugged it into a diagnostics tool and get the following error codes:

P0490 - EGR Control circuit high
P0489 - EGR Control circuit low
P1412 - ?
U0301 - Software incompatibility with ECM/ PCM.

Have seen a few threads that linked the EGR with the anti skid? I am planning on attempting to clean and check the EGR. Also read somewhere about a faulty fuel cap affecting the Emissions fault light on an engine or low quality fuel - which would make some sense as it happened straight after refueling in a french petrol station.

With the Anti skid service required I have also seen it is a known fault with Volvo that they may pay part of if not all to fix but not sure if this counts on the age of car I have?

All of this coupled with the fact that I will need to go to a french garage of some kind (Language barrier) has got me worried!

Car drives fine with the only exception being no torque on hills.

Any help would be really appreciated!
