Hmm.. My car definetly has the M103 engine (2.6)- the smaller version of the 3.0. Would this be the same procedure? Hopefully there is some way of switching them on, at least temporarily, to verify if the motors still work.. BTW i did check the fuse (#7).. it was intact...
hmmm.. the mystery continues!...
