Obviously, you didn't look at this site before you bought the car. If you had typed "Renault" into the search box, you would have seen the 163 pages of problems with Renaults. As you have found out to your considerable cost, they are c**P, but now you are stuck with it, so, I hope you have deep pockets, because you're going to need lots of wonga to get it sorted. You can try and take it back to the relieved person who palmed it off on you and get your money refunded. Why do you think they sold the car? because they knew it would be costly to repair it.
