Re: Renault Scenic 1 - General Advice On Interior Water Ingress

Hi There,

Im driving the Scenic II 1.9 Dci 2004 model and recently noticed that the aircon system releases its water inside the vehicle ( no doubt about). If the air con is not in use , there is no water inside the footwells.

Any suggestions how I would be able to solve this problem? Its obviously a blockage of the air con release pipe(s).

Looking forward to your comments.

It does sound like the breather pipe is clogged.

It will necessitate getting underneath and using a wire or thin rod to clear it, I would think.

Make sure the car is securely supported before getting underneath.



This job should never be complete - the day I think I've done it all, is the day I resign.

Re: Renault Scenic 1 - General Advice On Interior Water Ingress

I have had a 2000 Scenic for the last 8 years and had been plagued with water ingress through the sunroofs front and rear since purchase. Water collected in the spare wheel housing and on the passenger front footwell. After weeks of investigation I removed the roof lining, you can see the stains in the corners where water comes in, mainly on the nearside because the car is parked leaning over that way.

I checked the drain tubes and they were fine though the rear were a bit kinked over a clip in front of the lights. I lived with drips coming in on top of me through the square holes adjacent to the mounting bolts while I tried in vain to discover how water was entering, I even removed the sunroof assembly and could see potential entry points but nothing I could confirm as a defect.

Eventually using a small mirror I could see how the water entered, see my sketch for the answer. The roof adjacent to the corners of the sunroofs has shallower downstands than the straight seams next to the corners and this together with the fact that water on the sunroofs always migrates to one of the corners. I had read about capillary attraction but never experienced it directly, the amazing thing is that with the drain tube removed about 60% of the water comes in through the hole adjacent to the bolt and about 40% down the drain tube, total about a cup full from the lowest corner of the sunroofs after a night of heavy rain, so I think that blaming blocked drain tubes are a bit of a side show as even if partially blocked the tubes would still drain the limited amount of water.

And the cure? Two tubes of gel type Superglue applied to the underside of the roof adjacent to the corners of the sunroofs (total 8) to seal the exposed seams. It was a relief to find no fault with the sunroofs as they are the best part of a grand from Renault and you have to fit it!

Re: Renault Scenic 1 - General Advice On Interior Water Ingress

Interesting post Wyn.

I also have a 2000 Scenic and have had exactly the same problem you mention with the nearside rear sunroof drain from new.

I didn't discover the problem until the car was 18 months old when I found the spare wheel well half full of water.

I stripped the boot linings out and found the drain pipe was kinked by being trapped. I attended to that but it didn't fix the problem. As I never open the rear sunroof I ended up putting black tape over the sunroof edges and haven't had any trouble since, other then renewing the tape every 12 months or so.

Re: Renault Scenic 1 - General Advice On Interior Water Ingress

If you have an aerial leak, remove the aerial, fill the conical part with a general purpose silicone sealant, refit the aerial but don't tighten the nut fully until the sealant has set. This would generally be the next day. This will form a flexible seal on the roof which will not be affected by movement due to extremes of heat and cold.
It worked for me.
