Are the bimmerfest threads correct that the previous Siemens pump is being phased out for a new Bosh pump?
and does that mean all 2008's (productn approx sept)will be getting the new Bosh pump?
is your pump replacement 13-53-7-537-320 a newly modified pump of the old design ? or is it a new Bosh pump?
