When pulling my car out of the garage yesterday, I noticed some 'orange' liquid on the floor (a tablespoon's worth). So removing the bonnet, I found the source of the leak and had a quick tightening of pipes, etc. But poking out of the bottom of the air filter I saw this pink, what I assume to be some sort of assembly spacer, which I removed. This 620S is brand new (2 months old). This is going to sound like a very strange question, but should I put it back under the air filter?
