All E46 series BMW’s will suffer from a cracked chassis as some point in their life. This repair is what is required to address the issue and provide a permanent repair for the fault. The process requires the removal of the exhaust, subframe and diff to access the chassis, the cracks are then cut, filled and welded with a plate then welded on top. It is the same work we do on race car chassis preparation so is solid and permanent. Total time is one complete day.
