If I were to bring my c300 W205 in for service and I only request an oil change because I intend to do the rest of the scheduled maintenance myself (both A and B) is there a Warranty problem?

Yes.

 

Not sure which country your posting from but in the states it's not so much a warranty problem but depending on what issues you have they may be more likely to reject motor/transmission related issues on the basis that you don't have proof they were serviced properly. Depends on the dealer and what issues you have and what documentation you keep.
