The 2007 Audi A3 is a rather difficult car to maintain. You will need to go through the wheel well to access the turn signal and parking light, which may be a problem should the lining grow rigid. Accessing the fog lights is a lengthy process, requiring multiple panels and fasteners to be removed as well as other tools you may not have readily available. The engine air filter has a very convoluted set-up and may prove quite cumbersome to navigate around.
However, the 2007 Audi A3 does have its upsides. The oil dipstick is easy to find, remove, and read its level markers. The spare tire and jack kit are packaged together in the trunk, making it reliable to access in the event of a flat. Both the engine and interior fuse boxes are easy to reach, and the latter comes provided with a fuse puller for convenience.
