Amazing air filter blockage.

This is a BMW diesel that came in for a service, it had no complaints from the owner.
You can imagine my surprise as I went to change the air filter. It is the worse I've ever seen, totally full with leaves.
A good clear out and a new filter was all that was required.

Um, something not right here..

There appears to be a forest in your engine, Sir

Sure there's a filter under here, somewhere

There you are..

In the bin

Now that's more like it, nice n'clean
