Car doesn't start. Please help with advise. p1517

[Raden]

Good afternoon Guys!

I have purchased 2000 a4 quattro with 1.8t awt engine.
It was one owner and 52k miles vehicle. I supposed that it would be great. But few days ago, my car start making strange things.

First, it doesn't start from the first time. Just on the second or third. Next day, she refused to start up at all. The starter twists. I decided to take off "-" from the battery. And after 15 minutes, it starts. I have even make 20 mile trip. Then, i thought that it was some strange bug, and when i arrived home, i turned it off and start it up several times. No issues. The day after, i took my wife to the mall, and the car start perfectly. But on the traffic light - it stalled. we were staying there an hour. After one hour, i decided to repeat magic with "-" on the battery, and vehicle started perfectly.
I checked memory, and found several mistakes.

P1113
P0140
P1569
P1517
P1602

All that things happened week ago. Since then, i was staying outside the house. Today i decided to start it. But nothing happened. I will check all today's mistakes in memory later.

As i understand, first two - it is O2 sensors, and they can't make this happened. Also, the third one, because it is cruise control module. And the last one too. But, the code P1517 - that is the thing which i'm worried about.
What that could be?
Or maybe someone, can suggest good service or technician near Fort Lauderdale, FL?

From the P1517 code, in my opinion you are having a failure of the ECU relay. I had the same problem last month. It throws multiple unrelated codes. And yes, in my case taking in and out the relay from the socket did cure the problem temporarily, enough for me to drive the car onto a tow truck.

So, you just need to replace the relay?
Where it's situated? near ECU?
Grey one with ...253a or black with ...381?

You're looking for relay #30, if this hasn't already been solved. Open up your ECU box, you cant miss it. I had a problem starting mine sometimes, and since I've replaced that relay it hasn't happened at all.
