Audi A1 2013 7 speed DSG no drive

[Liger1956]

Just before we met my brother and sister in law last Friday her Audi A1 DSG gearbox failed. They were driving normally and all of a sudden they had no drive and no error lights on the dash.

 

Luckily I had a Bluetooth dongle and Carista on my phone and I did a scan. Although Carista could not communicate with the gearbox it found the following codes.

 

Basic OBD2:
P0841 (Pending) - Transmission Fluid Pressure Sensor/Switch "A" Circuit Range/Performance
U0415 (Pending) - Invalid Data Received From Anti-Lock Brake System (ABS) Control Module

CAN network gateway:
03041 - Energy management active

Engine:
04278 - Invalid Data Received From: Anti-Lock Brake System Control Module
04675 - ABS Control Module: Check DTC memory

ABS:
00401 - Left front ABS wheel speed sensor: mechanical malfunction
00402 - Right front ABS wheel speed sensor: mechanical malfunction

Airbags:
12850432 - Invalid Data Received From: Anti-Lock Brake System Control Module

Infotainment system:
03455 - Function limitation due to received malfunction value

Heater & air conditioning:
01316 - ABS control module: Please read DTC
01317 - Instrument cluster control module: Please read DTC

 

Also the dash now has ABS and ESP lights lit. The battery was changed in October this year so some codes may be from that.

 

Has anyone any ide what is wrong?

 

Also does anyone know of a good DSG specialist around Bourne near Peterborough as Audi want about £300 just to plug in their code reader.
