Hi All. So I previously asked about a mouldy/musty smell in my car XF R-Sport 2017 model. I was told it could be the cabin filter. Got a new filter. Changed it myself. Jag garage wanted £80! Took me an hour to do. I digress. Anyway. After having changed the filter. I'm still getting this smell. Any idea as to what this could be? 

 

Thanks in advance 

Get hold of an aircon bomb and try that. If that doesn’t cure it then further investigation is required.

I'd go for the aircon bomb too, follow the winstructions closely on it though as any deviation makes them useless.
