Water Ingress is the leaking or entering of water into a confined space, enclosure.
Scenics suffered from leaking sunroof which damaged the reicever for the C/L and immob in the interior mirror. Chech to make sure its not full of water. Apart from that you are stuck with a very poor quality immobilizer from Renault. If its any conselation,there are loads of Renault drivers in same position. Hope this helps.
The main reason he quotes is ingress of water in to the rebate.
Yes. Its possible to have wall penetration, beneath window sills leaking and water ingress through floors above including the roof
in its water container
could be the door seals
