Well, the issue has been solved. After about 7 hours of diagnosis, the dealer found the issue with all the codes being thrown up. It was a bent ecu pin and was fixed while they were troubleshooting. I had a suspicion it had something to do with the ecu plugs but I was suspecting corrosion on the leads due to the rain and humidity while I had it apart. Unfortunately, they did not tell me what pin it was that was bent but it was obviously an important one. Case closed.
