Have Volvo Questions? Ask a Volvo Mechanic for Answers ASAP
the P1081 code is immobilizer communication fault, most likely the antenna ring around the ignition lock, common failure.
the p1057 code doesnt convert to a volvo code. I believe it is a reference to a code being stored in the transmission.
volvo doesnt use "P" codes and I have found alot of times the P codes dont convert to a volvo codes or convert properly.
I would suggest finding someone that has the volvo VIDA or VADIS system to read codes and get the proper codes
