...basically the ones i dont know for sure..i under stand belts...but what i really wanna know what comes iwth the 90k plus mile service...if anyone knows...might be just a thing down here

 

my ecu light was also on before...now its off...was it reseted? or what?

 

Most dealers have a list/brochure of the Minor, Intermediate or Major services and what is included... in plain English...

And yes, they probably reset your MIL

 

Call the dealer and ask for explanation of charges. They will have a copy of work order. They are supposed to put all work performed in (legible) writing. For 90k service, check the manual. Also, check www.edmunds.com, look up your car, and see if it lists 90K service schedule. It usually does at least to 60K.

I'm going to take an educated guess.

valve assy - That was your CEL light, probably the Evap Canister Purge Valve.

belt-compr
belt-power They replaced your "fan belts"

element as - You got a new air filter.
