Hello, I’ve been driving a Legacy Combi as a diesel for a year, built in 2009, and I’m so happy with the vehicle. Only recently when changing the tires I looked at the vehicle a little bit more closely from below. In many places you can see superficial rust. At the exhaust system, on the chassis and also in the engine compartment there is rust now in many places. I don’t know that from my 10 year old Audi so much. Since I want to drive the car for a long time, I wonder if one should not do something against this rust in the initial stage. Is this rust questionable, or does it become a problem for a period of 10 years? Who has a tip on how to get this under control? In advance thank you for your help.
