Serious Mechanical Issues

[BluHwy]

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.

Hello Stephan, 

When you say..’ but the vehicle will not start…’, do you mean the engine doesn’t turn over when the starter is engaged, or it does crank over, but will not fire up? 
Also, while we are at it, how old is your battery? 
Kind regards,

Gareth.

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

The battery is new as of about four months ago.

Thanks Stephan,

Are we right in thinking it still isn’t cranking over then, rather than it’s an intermittent problem. 
Not cranking ( as opposed to cranking, but not starting) would have a limited number of causes, and should be simpler to fault find than an intermittent problem. Since your mechanic appears stumped, then it sounds best left in the hands of a trusted local auto electrician. 
We take it your battery is of reputable make, and has been tested to simply eliminate it from the equation. 
Kind regards,

Gareth.
