I don't think we can say what the problem is with any certainty. My 'Check Engine' light came on last Thursday and the EGR valve was replaced yesterday. Speaking with the dealer they indicated that they have had many D4s with the problem - they were replacing 5 EGR valves yesterday alone.
They also said they have Volvo data loggers installed in a number of cars which have required multiple EGR valve replacements, and that Volvo do not currently have a permanent fix.
