ABS ESP errors on 1.4 aua.

Hello all.

My lovely a2 (1.4 petrol aua engine late 2002) start to give problems again. Last mont i have warning lights for abs esp.
A quick scan show 3 errors in abs esp system and 1 error in the engine control module.
The engine control module eror is:
17961 - Barometric / Manifold Pressure Signals P1553 - 35-10 - Implausible Correlation.
And the abs esp erors are:
vag number 8z0 907 379B component: ESP 20 can v015
3 faults found:
01314 - Engine control module (79-00 Please check fault codes)
00810 - Sensor 1/2 for brake pressure (27-10 implausible signal - intermittent)
00812 - Brake pressure release solenoid (f84) (35-10 intermittent).

Recently i replaced the MAP sensor.
Allready replaced the brake light switch with brand new.
Allso i have replace the brake booster.
New brake fluid ,and new brake disks and pads.
And i can't find any vacum leaks.

But the errors are still here. Can some one tell me do i have to do any adaptations on the brake system?

Any help will be appreciated!!
 
00810 - Sensor 1/2 for brake pressure (27-10 implausible signal - intermittent)

Is the 1/2 sensor build in in the abs hudralic block (abs unit)?
 
Depends on age as there is two different ABS centrals. Early ones has the pressure sensor on the master cylinder and are easy/cheap to swop. Later ones have them integrated in the ABS central and then you need to replace the central at astronomic cost or go to specialist for rebuild
 
This is my abs block (the electrical part)

Yesterday i done full adaptations for the brake system, and so far 100km no faults found in the abs system.
Hope that solve my problems......
 
Perhaps there was a small amount of air in the ABS pump after the bleeding of the brakes. ABS pump primed and bled using VCDS.
