Hi,
I am new to this forum. I recently bought a 2012 Audi A4 Premium. I looked and have seen people done APR stage 1 or 2 to their cars. Is there any anything that needs to be done before I take it in to get it upgraded? Will it void my warranty? Are there any issues with the APR stage 1? I don't really want to have to upgrade anything else.

Thanks,

 

As mentioned on the APR website, you don't have to upgrade anything for stage 1. As for warranty, Get the 2 program package which lets you switch back to stock. Most(99%) dealers don't find out.
