I must admit I chuckled a bit when my dealer called me to say "don't bring your car in, Volvo has told us not to fit the updated EGR valves they sent us and they're going to issue another updated part."
I wonder what's going wrong with the valves? I mean, it's just an electric motor, a cam, pushrod and a flap that opens and closes .... they're not THAT complex
