Many owners cars are due for a 3-year maintenance which is really pretty minor stuff - certainly compared to other cars in this exclusive segment.
One of the more important 3-year maintenance tasks is to drain and re-fill the cooling system with a fresh anti-freeze mix. To do so, the front splitter needs to be removed as well a protective metal plate under radiators. Having done this procedure on several cars recently, we have noticed a few of these cars with AC lines that are close to or in contact with reinforcement plates of the radiator. On a car we have on the lift right now, this contact has visibly chaffed away part of the AC line and left unattended would no doubt cause a failure of the AC in the not too distant future.
The moral of this story is that when you are doing your 3-year service procedures, make sure you look around and look at this area specifically to make sure that you don't have the same or similar problem developing.
Below is a couple of pictures of the AC lines. From the photos, it is hard to see the beginnings of a cut on the line - but it is there. We addressed the problem by gently re-positioning the line to have 1/4" of clearance and then adding a section of reinforced heater hose to act as an additional safeguard.
