Sorry I can't help, but I wanted to relay that my S600 had faulty red error codes and it was obvious that the TPM sensors were not working right, and dealer said probably near the end of the battery life. Unfortunately, he said MB would not fix them under warranty UNTIL the battery was so weak it showed a DIFFERENT error - "NOT OPERATING - bring to workshop." This happened one week later, and now I have it in to dealer and they're going to replace the front 2 under warranty - but NOT the rear ones(yet). What a pain to have to go thru this, but I guess MB might be getting too many warranty claims from dealers trying to get money from corporate on work that was "reco'd" and perhaps not needed. Either that, or MB corp is just getting stingy and tightening belts all around - including these misc items. The good news is that it's covered under warranty.
Btw, I hear the original tire pressures lasted 60 months(my car's a 2005), but the newer ones are supposed to last 84 months). Good luck.
