E52 Cabin Aircon Filter Change
One of the easiest jobs to tackle on the E52 is to change the aircon filter inside the car. As my own E52 had been a smokers car (hard to tell when you purchase from abroad) I wanted to get as much of the smell gone as possible. The filter I used is a Blueprint ADN12519, just head over to eBay and you should be able to pick one up for under £10. To fit the filter you need to remove the plastic panel in the passenger footwell, which you just pull off. Then you should see a thin plastic cover that you unclip and remove. The filter has be squashed together a bit to get it out and the new one carefully pushed in place. If you need a little help the following video should help.
