When I start our Z4 E89 I get a smell of split milk which does go after about 5mins but may recure.
I’ve read on other sites that this maybe due to the micro filters needing to be changed in a/c unit under the glove box.
What does the collective Z4-forum hive mind think about this?
Thanks

I’ve not noticed this in my car, have you spilt milk in yours? :oops:

I change mine every year, only takes about 10 minutes to do it. Three screws under the glove box in the footwell, pull away the panel and the filter is tucked away near the right top from memory. The last filter I bought from a link here on the site and I think it was about £8 but you can pick genuine BMW ones on eBay for about £10+postage (I think BMW charge about £75 to change it)
 
I had a similar problem when I had my E85. I tried several air con cleaners without success and eventually paid for an auto-electrician to carry out a deep clean of the system. Still I didn’t manage to get rid of the smell. Time came to sell and when cleaning the carpets under the seats I discovered a container of milk. My wife had used the car to pop to the local super market to buy some groceries and left the milk under the passenger seat where it had lain for some time. When it had gone off it had expanded and pushed off the lid releasing everything onto the carpet under the seat. It was a nightmare. The, only solution was to take out and replace the carpets. Needless to say we are ultra careful about checking what is left in the car now. :oops:
 
It does stink - I did the next door neighbour a favour by taking his son to work one day - the young fella put his lunch box in the boot of my nearly new Saab turbo - yes, his milk bottle leaked out - The car was never the same after it lost that new car smell - However not as bad as an old fella i know, he used to buy fresh fish from North Shields quayside - the surplus liquid drained off the fish - he sold the car after a few attempts of cleaning !
