Hello,

Code 2848 relates to P0190 - fuel pressure sensor open circuit.
Suggest checking that the connector is plugged in correctly, check that there are no lose pins or broken wiring back to the DME.

A good article:

See wiring diagram below.

Regarding the overheating issue, did you bleed/burb the cooling system properly?

A good article:

Cheers, Boris
