Just rectified a heater fault that I thought would be a really easy fix. Other garages have tried unsuccessfully to rectify it. Simple at first I thought, car heater does not work when stationary in traffic but blows warm when driving. Very simple I thought, electric heater pump failure...

Hi all. I have been having a bit of a saga with an intermittent hot starting problem on my E46 330d which culminated with it not starting at all. Local garage recommended by a friend(in rural France) turned out within the hour & took it away. They identified it was the fuel pump under the...
