Question

I have fault codes P0335 & P0727 on my BMW Z3 automatic also the DSC and auto gearbox warning lights are on

Answer 1

Hi there,

The code P0335 is for the crank position sensor. The transmission also uses the crank position sensor to determine the engine speed. Replacing the crank sensor should resolve both codes for you.
