Fitted new Egr from dealer and still the same problems
If I rev it over 4000 rpm the anti skid comes on and goes into limp mode em light comes on turned the car off and on again and anti skid stays out till it is revved again but em light is on the whole time same fault codes so where do I go from ...

Thanks for all the info greatly appreciated

And the info light is on

Code 0101 is on it also engine control unit comms faulty permanent but didn't think this had anything to do with it Volvo never mentioned it
These were off a Delphi scan along with A030 AND 0108

I have my 2005 s40 in Volvo and they say my Egr is knackered but before I got this car I was told it had a Egr fitted
So what I need to know is there anyway of finding part numbers correct for my car as I need to sort a valve but they all have different numbers on them and not sure if the Egr is ...

Codes are p1412 p0404 and p0406 all Egr related and Volvo have said the anti skid is on the message screen because of the Egr valve

But the car is driving normal no limp mode

I have my s40 in the stealers for anti skid since Monday and they rang me today to say its the Egr valve that is causing it to come on its not in limp mode driving great
How come the Egr valve interferes with the abs should they not be seperate systems as one is safety and the other is economy
