Whereabouts is the carpet wet then?
Even a perfect looking membrane can leak. About 6 inches back from the front along the lower edge, the metalwork kicks in a bit. The membrane tends to lift away at that point.
If it's not coming in there then it could be as I suggested, from the roof motor well.

Fingers crossed then.
Definitely need to find the source of the leak though or more problems will arise.
Under the RH seat is the yaw sensor. If this gets wet it fails.

So I was looking for the source of the leak, and decided to relocate roof motor as Ive read so many horrors stories well abosultely stupid idea. If your roof motor is in housing and there is a lot of tape around it don't touch it.
Firstly housing inside and motor were absolutely in perfect condition but once its out there is no way back I guess. So relocate it to boot space but because I fiddleed with it and now it's not in up right position oil level dropped. So I can here motor running but no action from the roof.
Going back to leak rear is OK so it must be from the front drain points. Checked membrane again and as mentioned before perfect condition all over. To summarise I made it worse by causing a problem with roof and not finding water leak - just great

If I had a tenner for every time I started on a course of action only to find it both redundant and giving me extra grief by making it worse first, I'd spend a lot more time in the pub!

I'd dispute that tbh. I did one yesterday. The well was bone dry and the drains were clear. The motor worked perfectly. But when we lifted it out the casing was full of brown water. We would not have known until the motor died.Simonsen wrote: ↑Thu Mar 23, 2023 2:28 pm So I was looking for the source of the leak, and decided to relocate roof motor as Ive read so many horrors stories well abosultely stupid idea.

If you use the search function on the forum to guide you through the relocation you will see many references to the oil level. In it's normal position it is almost upright, but when you put it in the boot at angle the level does not drop, it merely sits differently in the reservoir and one of the inlet ports will be uncovered, allowing the pump to draw in air instead.
All you have to do is simply stand the assembly upright, remove the fill screw on the top and top up with hydraulic jack oil until it spills over. This will still leave a small air gap though.
Put the motor back in the corner and all should work fine. You may have to assist it up and down the first time as it self-bleeds the air out.
It is most definitely NOT a 'stupid idea' just because you were one of the lucky ones.
This comes across (maybe wrongly) that you blame the advice you were given for introducing another fault!

Thanks for above. I thought it might me relocation and oil level issue. Well it's becoming a norm weekend come and I am searching for water leak. Again I had a puddle of water behind passenger seat. Tested front draining point all OK it's coming straight down I tested rear roof ones again all working fine water flows straight down. Membrane in doors ok so why oh why do I still get water in there??
