Defect investigations
Rear Lamp Illumination
In a letter submitted to the Office of Defects Investigation (ODI) dated August25, 2011, BMWindicated that it will conduct a voluntary recall campaign to remedy the subject vehicles.The issue involves the rear lamps in the vehicles body panel.Through normal vehicle use over time, the rear lamps ground wiring and associated 8-pin connector can experience an increase of the resistance at the electrical contact points.This can lead to intermittent or permanent loss of the rear lamp functions which include tail, brake, and turn signal operation.The recall consists of modifying the rear lamps in the vehicles body panel by adding a secondary ground connection in parallel to the existing primary ground connection.An 8-pin connector that attaches the primary ground wiring to the rear lamp assembly will also be inspected and replaced if necessary.BMW will complete dealer notification in September 2011 and will begin owner notification in October 2011.All 3 series sedans (except for the M3 sedan which utilized a different rear lamp assembly) that were built between September 1, 2001 and March 1, 2005 are included in this recall, totalling approximately 241,000 vehicles.The action taken by BMW is sufficient to resolve the issues raised by this investigation.Accordingly, this investigation is closed.

Bonjour, les rflecteurs zkw de mes feux xnon sont bruls. Mes feux n'clairent plus.
Factory bi-xenon headlights gradually dimmed. By 77k miles the light output was too dim to safely drive at night. Compared to a new model at dealer with xenon lights and found very noticeable difference. Mechanic analysis found metallized plastic reflectors on xenon bulbs had burned and lost their reflectivity. Replacement reflectors are not sold as service parts by bmw, so remedy involves complete replacement of headlight assembly.
I received a letter from bmw ststing there was now a recall for the bad ground wire on the rear taillight assembly that caused the metling of the connector. I had already spent $400 for the fix, now they recall the part. Bmw north america took too long to do this, and I am going into the delaership to see about getting a refund for the service I paid for that they would not cover.
