Audi A6 P1653 ABS issue

[RodrigoKinast]

Hello guys,

My name is rodrigo, i am from Chile and I must write here because my audi a6 2.4 2008 multitronic is making billycocks on the front of my house.
In 2015 I changed the original battery of my car because it was a bit difficult to turn it on sometimes, the battery dies fast... Because of that I bought a new Hankook battery with the same specifications as the old battery... Probably 2 or 3 months later the car begins to fail. The symptons were that if I accelerate the car and the Stability control turns on at this moment, the car dies... even though it was on "D" was the same as the car was in "N", I could accelerate but the car didnt move and the audi decreases speed till I have to stop and the car still could not accelerate in this moment if you put "P" and then I want to put D it was blocked... I leaved around my car because it didnt give me trust to drive to my work. Now, I am trying to solve this problem... I charged the battery after these 3 years. Today I went to a friend that have a good scanner and he gives me all the codes that appeared.

He connected the scanner and there were a lot of faults...:

then he went to the brake system:

After all he cleared all the fault codes but inmediately appears these fault codes:

I want to enjoy my car but anybody in my city could tell me what is going on with my car.

It is important to say that today I used my car and I accelerated in a traffic light till the whells shrilled and the car did not die as before. In the screen appears a fail in the tail lights angle level, but the lights work perfect when I turn on the car and the lights are on it regulates good.

I suspect about there is something wrong with the battery... i think that the battery cant give a good intensity to the sensors or abs module and thats why I have more problems..
IN ADDITION, THE SPEEDOMETER DOES NOT WORK, WHEN I HAD THE FAILURE 3 YEARS AGO IT WORKED GOOD....

THE LIGHTS THAT I HAVE ON ARE:

the car works good I can go everywhere but the traction control doesnt work good..

PD: Before I changed the battery when I turned on the alarm closing the car, it makes a "beep", now it doesnt make this "beep" so the alarm failed too I think that it goes deprogrammed.
PD2: Finally when I turn on the electric brake to park, it only turns on if the car is off, on the contrary the light of the brake blinks and if the brake is on and I turn on the car, I have to accelerate in "P" to 2000< rpm to turn off the brake.

SORRY ABOUT MY ENGLISH, I TRIED TO DO MY BEST.
I WILL BE VERY GRATEFUL IF SOMEONE COULD HELP ME.

I would check alternator. Maybe is not charging enough. Switch off all electrical consumers (radio, lights, A/C, etc) and check voltage until engine is running in idle. The voltage should be around 14.2 V
