SIB 41 02 23: Water leak corrosion

Water leak corrosion on BMW G07 models (2019–2023); BMW explains the cause and the approved repair.

BMW service bulletin · NHTSA ID 10238074 · May 2023 · also written SI B41 02 23, B410223

What it covers

A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.

Due to prolonged, normal body flex acting on the vehicle during its service life, a small indentation and/or a crack can form in the body sheetmetal in the right rear wheelwell (aka wheel house). Potential water ingress and a risk of corrosion is possible.
