My A3 is up for service soon and as a first time A3 owner I really don't know which brand filters I should use or which are best for my car. Could someone please help?

Hello Kaif,

Thanks for being in touch with the forum.

I guess we are right in believing you are going to carryout this service yourself -? 

In answer to your question:- If not using genuine VAG filters (at discount) then the only filters I use are Mann or Bosch. 
I would not use ones which come ‘free/included’ with an oil purchase! 
If you are uncertain on what brands of filters to use, have you yet decided on what brand of oil to use? 
Incase it helps, I use Quantum (was/is recommended by VAG) which I buy at the most competitive price via. EBay - as with the filters.

Kind regards,

Gareth.
