Tomclio 1.2
The water noise you are getting from your sunroof could be due to the glass not having an air deflector on it. If the noise is present when the car has been standing in the rain or after washing it, and is ONLY present for a short while, it will be the sunroof glass. I have a 98 S reg 1.4 rt and it does it as well. Renault have just released a note on this subject and it involves replacing the glass.
This is what Renault say about it.
Sound of running water after washing the car or when it has been standing when raining.
It is caused by an accumulation of water on the front part of the sunroof (between the frame and the glass panel)
Solution: Fit a glass sunroof panel with a deflector.
For manual sunroof: PT number 8200 253 555 £88.50 + Vat
For electric sunroof: PT number 8200 253 556 £88.50 + Vat
Personally, Im gonna live with it. Once it has dried off the noise goes anyway.
Hope that helps you all.
