I bought a 2008 Laguna estate in June from a Renault main agent. About three weeks later I noticed a water ingress problem, which I believed to be the sunroof. I contacted the dealer who told me to take it to my local Renault agent to have it repaired and to invoice them. The local dealer said they would have to bill me direct as they did not have an account with the other dealer.

The Surrey dealer then said they would repair my car, and I took it to them, using one of their courtesy cars in the meantime. Two days later they told me my vehicle was repaired, and the problem was with the rear door seals, which they had modified.

About a week later the leak became more apparent, so I phoned the dealer and once again they booked it in. I have their courtesy car again.

Last week the Service manager called me to say they had indentified the problem and it is a cracked sunroof cartridge, which they say needs to be replace at a cost of £2700. They suggested I make a claim on my insurance to cover the cost. As I have not had any accident I declined. They then said they wanted me to meet 50% of the cost, which I also declined.

The dealer then contacted Renault UK and I have been in discussion with their customer services department. They have now informed me that Renault UK are prepared too meet 40% of the cost, with the dealer contributing just 10% and myself 50%. I declined this offer as well.

It is my belief that the dealer is fully responsible for the repair, whether or not they knew the problem existed when they sold me the car.

I am due to talk to the service manager on Monday (who incidentally I have discovered is the dealer principal) and I would like your advice on exactly where I stand.
