Hi,

Can anyone confirm (via bimmerlink or datalogs) what their N55 M2's coolant target is? I believe it is 80C (as shown in my old datalogs prior to blowing my engine and getting it swapped from another N55 M2) but my shop keeps saying it should be 100C. My fan and waterpump are running at 100% duty cycle constantly but for some reason it won't go below 100C post-engine swap.

I believe non-M2 N55's do in fact target 100C, but as far as I can remember, my coolant was always pegged to 80C (with oil slightly above that).

TIA!
