audi a3 2007 2.0T

automatic transmission 199k mileage going up - still my daily heated leather seats double sunroof oem rims painted black on winter tires recently replace with good ones. regular maintenance always on time. change oil every 4 to 5k engine and transmission still good. only use 91 octane gas and can go more than 600kms on a full tank on highway driving. issue: some rust due to age, lights on dashboard. engine lights on but doesn't affect performance.
