Have a MB dealer check your VIN in VMI for all outstanding recalls and service campaigns applicable to your vehicle.
MBUSA Service Campaign 2005060008 JUN06 (e320 VIN range: A014562 â€“ A418838) covers BCM programming and/or replacement. Note Service Campaigns do not expire therefore if included you are entitled to a no cost repair.
Upon inspection if it does turn out to be the BCM and your vehicle is not included in the campaign mention DTB P-B-54.21/155a depending on the BCM installed, they will flash or replace it. Normally a DTD does not extend past warranty however, it is a known problem and MBUA considers the original BCM defective therefore, request cost free modification.
