Hello Mursal Thanks for the response.
Will check out the gutters.
If the pollen filter was leaking would it be a lot of water ? and could it find it's wayto both sides of the van.
Has Vivaro owners out there had a problem with rusty water being forced up the front screen pillars and ending up all over the sides of the van. Water seems to be collecting somewhere and being thrown out during the journey. Any help much appreciated.
