the dealer dose not wanna do the tranny or the diff oil and i have 30k on the car!?!?! i even called bmw north America and there no help. Is this right what should i do??? they say the service booklet is old
*this is what the book says
M3 with standard transmission: At every 3rd
oil change:
– Change the transmission fluid and clean the
oil filter (NOTE: this does not apply to the
optional M-DCT Drivelogic transmission.)
– Change the differential fluid.
*6 speed(my car)
