All Mk2 172 go and check your jacking points. I was advised from someone on here to check mine about a week ago, and seem to have caused a stir in Renault (including in France!)
My Cup has just hit 8000miles since I bought it new about a year ago. The car has only been jacked up by Renault. It now has a bent o/s jack point. It looks as if it has turned in the way towards the car. Although I have kicked up thick sh*t about this, the law states that I must give the dealer a chance to fix the prob, and if I am not happy with the repair, then I have a right to reject the car.
The car now is with the dealer (Renault Edinburgh),that I bought the car from, who know think that they can repair my car, however, the Garage is getting no backing from Renault UK. They say that this should not have happened and are taking no responsibility for the repair. It has now gone to a head technical person in France who is anylising photographs as we speak.
If it is found to be a problem with car/model, there may be a recall. Please post back if you have/had this sort of thing happen to your car.
