I'm expecting to take delivery of my new A4 Avant 2.0 tdi (170) Sline in a few weeks. Any advice on how one should drive ones new vehicle? I know that nowadays modern engines don't require to be "run in" like they were years ago where you had to keep below 50mph but is there a best way to look after the engine in it's early life which may lead to less problems as it clocks up the miles? The last new car I had was a MKIII Golf GTi and when I took delivery the guy told me that the engine had already been tested during manufacture at full speed so I shouldn't worry too much about how I drove it! Still tended to take things easy in the early months until things started to loosen up. I've read somewhere in the past that giving your new engine a bit of a workout every so often aids the sealing of rings or something - not too mechanically minded but would appreciate any comment on this so I'm giving my new baby the care and attention it deserves! Thanks in advance.
