Iam a factory trained saturn tech was one for over 16yrs and I can tell you I have seen all those codes before there not uncommon. Except for that weird V code I dont know what thay that code is all about. The two codes I worry about first is the P0621 you need to have the alternator tested and the battery tested. Also make sure the battery cables are clean and tight. Thats where I would start with that code. Next I would work on the P1811 code I have seen that code left unfixed and the transmission destroys itself inside. So why did they say it needs a computer?When they replaced the computer was it a used one or new one?
Please consider a to help us answer more questions.
