Having only owned my C-Class for a couple of years it was due a B service recently. I set about the service and when it came to the pollen filter I was shocked! Full service history but no mention of the pollen filter being changed but the two clips that go either end of the filter were missing so the filter has been changed at some point. Anyway a picture says a thousand words. First picture is the intake side. Second the back. Third a close up I'm away to buy an Aircon bomb!
