Enquire for guarantee

Hello town, I bought a Volvo V70 BiFuel, Bj, first registration 12/2005 cheaply about 150 km away from my home town. It is a used car dealer. According to the contract at least 12 months warranty. Now I did not notify my dealer if the gas control is defective, but immediately steamed to my Volvo branch. Then I left the whole thing behind …. Repeeratur was on 17.03. Repeeratur was on 17.03. Repeeratur of the accumulated Ko 170€ now takes place in November. Now finally the question, can I easily assume that this will still work? Or do I have a formal error about the non-notification and the very late request? Thank you very much.
