Always stick to the manufacturers service manual when it comes to servicing. If higher or lower mileage makes a difference that'll be reflected in the prescribed schedule. Lot's of men have fucked up VAG DSG boxes, for example, by fixing stuff that isn't broken and that you're not supposed to touch... and by not following specified methodologies where fluid replacements are specified i.e. in wet clutch DSGs.
You should use a "charcoal" pollen filter - presumably that's the heavier one Panel mentions - if you drive primarily in the city, they're much better at dealing with emissions than the bog standard paper ones. I change mine every 40,000 kilos or 2 years despite the manufacturer's (VAG) recommendation of 60,000 or 2 years, mainly because I tend to have the blower on low constantly and it's an easy 5 minute job. Interestingly, the pollen filter is always filthy when it comes out and it's generally followed by leaves, dead bugs and other light debris whereas the air filter, replaced every 90,000 kilos or 6 years, is generally spotless - although I have taken to giving it and it's housing a quick rub of the vacuum cleaner at every service which I do every 20,000 kilos or 18 months, assuming the car doesn't ask for it first which none of my VAGs ever have but the spec is 30,000 / 2 years / sooner if requested by car's ECU.
