Which cars are affected
Prices found for G01 X3 M40i and E60 5 Series. Applies to any BMW with a sunroof or panoramic roof.
Most BMW sunroof leaks are clogged drain tubes, not a failed seal. Each corner of the roof tray has a drain; front drains exit near the door hinges and rear drains near the rear wheel wells (on the E60 behind a star-shaped grommet behind the wheel-well liner). Owners clear them with a thin plumbing snake or trimmer line. Leaving a leak can soak the rear amplifier and modules, which is what turns a cheap job into a big bill. On some newer X5 and X3 models, also check the shark-fin antenna seal; see the shark-fin antenna settlement on our recalls pages.
