Hi. The pressing the start button, nothing happens but dash lights. 

The battery is new as of about four months ago.

Greetings.  Is anyone willing to try answering my question about my C6 A6 mechanical issues?

It began as a low tire pressure warning. And within minutes, the ESC warning was on and the Engine warning light was flashing.

My mechanic is unsure what would cause this.  But the vehicle will not start. 

I'd appreciate any advice you have to offer.

Greetings. What would be the largest wheels and tires that will work on a 2006 A6 (C6) Avant Quattro?  Are there any adverse effects from increased wheel and tires from Original Manufacture's Equipment?   Thank you.
