On eBay @ "4 for $55" - likely old takeoffs with dead (non-replaceable) batteries? And yes, they do age out regardless of miles . . .I have never had sensors nor do I know what ours look like. Sometime ago someone posted that Ebay had a set of 4 for $55. Is there a p/n for these that I can search for because the info I put in does not seem to work?
Really, are these TPMS sensors necessary?
Some people consider me a fanatic because Saturday morning, especially in the summer, everything that rolls gets a full fluids check, battery post inspection and tire pressure check all the way around.
I just got a 2009 451 with a dead battery and am slowly starting to unravel the mysteries of these cars, even though I worked for Chrysler and then for Daimler for several years. Still looking for a factory service manual like Mercedes sells, even if on CD.
