My servicing dealer told me (at my first warranty service) that an update for the engine computer on my car is available and should be 'installed'. When I asked what it was designed to do/fix I was only told I could look it up on MBUSA. When I couldn't find anything about this fix there, I inquired further and asked for specific service bulletin (etc) numbers was told the ONLY info they have is a notation on the machine they use to read the engine. They tell me the install will take 3-5 hours to complete and I want to know exactly what the change is supposed to accomplish.
Has ANY one got any info on this? The dealer is certainly not forthcoming.
