I took the air filter out of my new Z3 today just to check the condition and to make sure I ordered the right one from Autodoc.
The filter installed is absolutely filthy and full of leaves, etc. So I checked the date stamp on it.
It is a genuine BMW one with a manufacturing date of 23/9/2000. So I deduce from this that it is the original factory filter (as my car was built December 2000 and registered April 2001.
I have a stamped service book with 12 entries in it. No invoices, though! The last service (2021) has it written on the entry that it had a new air filter. That was supposedly (!) done just 1000 miles ago! There is no way my filter has only done 1000 miles.
Now either someone has been lying, more than once, or a garage somewhere has a stock of 20 year old BMW filters that they haven't used up! I'm going to plump for the former.
The other thing that is making me even more suspicious now is that the last 10 service stamps, going back to 2007, are from the same garage. That in itself is not beyond possible but there are no hits on Google for the company name on the stamp. Bearing in mind the last service was supposedly in 2021 I would expect the garage to be still around.
