2004 V70 FLOODED, ELECT. ISSUES, HAVE CODES, IS IT WORTH REPAIRING?

Hello,

My 2004 V70 station wagon was flooded. Water in the cabin up to the bottom of seats. Ended up with a number of electrical issues. Removed the carpets, vacuumed the interior really well, and parked a dehumidifier inside for several days. Some, but not all of the electronics came back. Car has 148,788 miles, is in great condition otherwise, and runs great.

Current issues that I'm aware of are: Check Engine light is on, power windows don't work from the driver's seat, power door locks don't function, (can lock, and unlock manually), can't open the rear cargo area door, overhead interior lights don't turn on, sunroof won't open.

Here are the results of a diagnostic scan I had done:

CODE 1A52 COMMUNICATION WITH CONTROL MODULE SIGNAL MISSING
1A54 COMMUNCATION WITH PSM CONTROL MODULE SIGNAL MISSING
1A5C COMMUNICATION WITH UEM CONTROL MODULE SIGNAL MISSING
007D SEAT BELT TENSIONER, MIDDLE RESISTANCE TO LOW
00D5 SRS LAMP COMMUNICATION FAULT
E001 CONTROL MODULE COMMUNICATION FAULT
0048 INFLATABLE CURTAIN (IC), RIGHT SIGNAL TOO HIGH
011B CONTROL MODULE INTERNAL FAULT
0100 COMMUNICATION BETWEEN CONTROL UNITS, PROBLEM WITH ECM
4340 FUEL HATCH LOCK (Note: latch was not working but now works fine)
0030 WHEEL SENSOR LEFT REAR FAULTY SIGNAL

Considering the age, and milage, it probably doesn't make sense to spend a lot on this vehicle. If I could get the important things back (door locks, rear hatch door, and solve check engine light issue), I could probably live with the rest.

Would appreciate any ideas about the best path forward .
