Hi all. Took my new (3 days old) polo tsi for a little trip up and down some steep windy roads in the Dandenongs today (couldn't help myself). After I stopped, noticed a smell of maybe it was hot oil (definitely not brakes tho') - sort of greasy and unpleasant. Dissipated after a while. No warning lights or difference in its performance. - Is this "normal", given that it's only new? thanks in advance for any thoughts.
