Hi all, only recently purchased my audi A2 but just noticed that my coolant level is below the recommended minimum mark. Is it common for the car to lose coolant, is it a fault that the car has not warned me? If this is quite common what is the recommended coolant to use? Also my clutch feels quite stiff and I tend to feel it slightly click as I depress it. Also is this quite common? I have a 1.6 FSI sport on a 54reg. Thank You!
