Difference between Engine Types for 2010 E550
Does anyone know if there is any difference between engine type V8 273.971 - 5.5 Liter and V8 273.966 - 5.5 Liter?
I notice that mines is 273.971 (Vin Lookup) while doing some searching for parts. Many times a parts search will use these two options to differentiate which RWD model we have. I'm not sure if it really makes any difference or if it's a different year build etc. Just interested and couldn't find anything when doing a search to explain much on it. Thanks
