Hi I have a 2004 E46 M3 and despite replacing the bonnet sensor and pump relay, I have been told that the SMG pump needs replacing....
Is there an aftermarket part that can be fitted? or a specialist mechanic who can repair the sensor inside that is the element at fault?
Quotes for replacing the pump coming in at 2,300 - 3000 which seems extortionate!
Help or advise would be fantastic!
