No luck with BMW… That or the parts guy just clueless.
RBF 600 by Motul was all I could find locally but not only was it more expensive than the ATE Super Blue but you only get 500ml vs 1L.
Still not sure what I’ll go with as I’m going to do a bit more reading and research first but for the time being I’m going with the normal DOT 4 so I can get the car on the road and will just flush out the system in a week or two.
