530 Engine Problems (archive)

Hi All,
Just got back from a long drive and had a big problem, while accelerating at over 110mph the engine stumbled and then lost all power. I pulled over and it was still idling but rough as hell. Turned it off and had a look under the hood but nothing much to report, waited a few minutes and started again and let it idle for a while. Finally the idle smoothed out and I drove off slowly for the rest of the journey. I checked the engine codes when I got back and got 1215 for the air mass sensor, should this have had such a big effect. I thought the EMU would just switch to limp home mode. Should I just replace this expensive sensor or look for something more serious. No signs of vacumn leak, head gasket problems etc.

Thanks for any help,
Gary
