Well, we all have seen throughout our automotive careers the effects that little furry critters and cause to our vehicle systems.

Most of the times, I will find a small nest buried between the crevices of a vehicles engine compartment. I have found nests inside air filter boxes. We sometimes find a collection of nuts and various other bunches stuffed somewhere underneath the hood.

Today marks a new story I can share over a cup of coffee in the future. We have a 2006 Audi A4 with a bad fuel smell, and large leak detected in the EVAP system which was causing the check engine light. After using a smoke machine we found a large leak coming from a fuel ventilation line. This led us into the trunk to to access this line from the top so we could see how severe the hole/crack is, and also what could have rubbed against this line to cause such a tear?

Once we removed the cover from the trunk, to our surprise there is more than just a broken line. The line clearly has been chewed through, with small teeth marks, and the fuel tank itself has been chewed completely through. The culprit of this issue, is a few small furry guys
