There's a lot of conflicting info out there ref Audi A4 tyre pressures.

For example on my Audi A4 2.0 TDI 35 with 225/50 17 tyres,  on  the  Kwik fit website their recommendation for my exact model is  32f/29r,   the Audi door plate sticker says 36f/33r.(this is the comfort setting, the non comfort setting is higher)

The unwritten rule seems to be  the later the model the  higher the tyre pressures? Are Audi doing this to make their mpg figures  look a little better in today's "green world"? 

Higher pressures give a harsher ride and can lead to uneven wear.

 

Hello Peter,

I recommend you stick with the tyre pressures specified for your tyre size - as shown on the door plate. No reason to consult any other available information. 
Kind regards,

Gareth.
