Hi, my hdi is showing a mil light. Got it diagnosed as follows. 4 fault codes. 0380 glow plug circuit,1403 1404. 0100 mass air flow sensor circuit. The car won,t go above 2500 revs, think this is limp home mode. We cancelled the fault codes but they came on immediatly on start up. Car starts ok. Have checked for bad connections around the glow plugs and mass air flow connection. nothing obvious. any help appreciated

thanks
