Renault Megane 2015 Problems

Modern engines do use some oil, and it's wise to check the oil level regularly, say once a month. Some engines also use more oil during the run-in period, which is what you're going through now. It's hard to say whether your car is using too much or not. I suspect it's not, but if you are concerned about it have the dealer conduct an oil consumption test to determine exactly how much it is using. That's the only way of telling if it's too much or not.

I understand your frustration; I also agree that diesel buyers should be made aware of the possible consequences resulting from the way they will use the car. Blocking of the DPF because of being used on short, low speed trips is quite common across most brands, so it could be argued that you should have done you homework and known that. As to whether you have good grounds for a refund I can’t say, but I suspect you could request a refund, or part refund, as a gesture of good will from Renault.

We're passing the message along to Matilda.
