Depends on the warranty. I brought my CRD to the dealer with a burnt out AC condensor fan (packed with mud) and a diesel leak from a hose I damaged while replacing the EGR. It was an aftermarket extended warranty I bought from CarMax. The dealer simply put in the claim and got paid. I told them that anything not covered I would do myself so it was in their best interest if they wanted to get paid. I don't know what they said to the warranty company, buy they approved $1k worth of repairs less $75 deductable.
