Some sources say that BMW is currently changing the LED taillights on about 25,000 1 Series vehicles due to water leaks. No other lights are affected by the leaks. The 1 Series Coupe (E82) and Convertible (E88) for all production years will be affected.
Good thing this is not really a safety issue. Thus, no recall has been issued yet. BimmerToday reports that BMW will just be changing the taillights when 1 Series owners go to their regular trip to the dealer. Approximately half of these 1 Series owners have already had their taillights changed at their dealers with no extra charge.
