Well I had noticed that the windscreen is developing condensation unless I turn the heater up - which eases the problem. Having read a thread on here I will be going and getting a new pollen filter at some point. The aircon works fine too.

The other thing I have noticed is water in the spare wheel well. I have had a look at the seals on the tailgate after the car has been soaked with rain- and found nothing. I actually think the two are unrelated ie have developed at different times.

Is there a common part which lets water in?

Thanks for any help guys.
