So my 2008 135i with 180,000kms, has been in the process of getting bodywork done after an accident for the last month and finally the car was finished today. The tech at the bodyshop had trouble starting the vehicle (which was never an issue before I brought it in) and it was taken to a BMW dealership across the street. What they found was a corroded and snapped ground wire that mounts onto the frame. The dealership provided the following pictures.
The dealership has said that BMW does not supply the individual part for the connector that is snapped and the whole wire has to be replaced for $350, and it would take 8 hours of labour since the subframe and fuel tank has to be dropped. None of this cost would be covered by insurance as it was not related to my accident. Paying over $1000 CAD seems absolutely ridiculous to me for this issue. Would I be wrong to assume I could simply strip the wire and crimp on a large ring terminal to bolt onto the frame? Has anyone else had this issue?
