Thought i'd share this with you all. My IS has had a bit of a odour in it for a little while now, smells like farm yard . I thought it was just the time of the year with the farmers spreading the stuff around and all that ,but it got worse, just smelling in the car, when you got out, good air all around. So yesterday i checked on the site about cleaning pollen filters. Just cleaned it out and found the cause of the smell, stuck on top of the filter was a dead snail, just the shell no-one home don't know how it got there.
