I started the full service on my 5 today, I cant believe the faff with removing the air filter!! It took me 30 minutes to remove it, unbelievable!!
Anyhow, once removed I found it to be in a very bad state, I don't think I have ever seen an air filter so dirty, if anyone in the know is reading this then could you take a look at the pics and advise if it is supposed to look this black after 15k-ish miles?????

Mine was a hell of a lot worse than that at 93 K when I did mine. Funny thing was it had a comprehensive BMW service history from new.
Only goes to show the dealers don't always change them at service, even though it's only on the service schedule as once every third service 60 K.
