Thanx Philly, I will change the thermostat immediately
Do you know the function of the small 'twist cap', wich our Ti's don't have ?
And yes, I did mean the expansion tank sensor, it will probably just give a warning too, like the windshield washer
I bought a Z3 M differential, but it doesn't fit offcourse, the input flanche has 4 bolts in stead off 6 and the output flanche is 94mm where the Ti is 80mm.
I do have some 3.2 M3 shafts, but I don't know if it will fit.
I am getting grazy because of all the problems, why didn't I just bought an Z3 M Coupé
