ESP Warning Light - Car will not start, advice sought.

[North2007]

After successfully changing a turbo on 4.0 D3, it was running. Brake fuild warning light came on (car was jacked up at the front). Fluid was added, however message to seek assistance came up on the display. Scanned with Gen Ross tech VDSC:

18259 - Powertrain Data Bus
P1851 - 000 - Missing Message from ABS Controller - Intermittent
18255 - Please check DTC Memory of ABS Controller
P1847 - 000 - - Intermittent
18262 - Powertrain Data Bus
P1854 - 000 - Hardware Malfunction - Intermittent
18289 - Powertrain Data Bus: Missing Message
P1881 - 000 - Acceleration Request - Intermittent

The rear pads recently showed as low too on the scan.

Any advice would be appreciated, should a be checking fuses?.
