Ok update. I contacted the Service manager to find out whats going on.. I heard from them on Friday and said they were running the machine to try and get the code to come back up to no avail.. Drove it around again on Monday still no codes coming up.. They said it is acting like a faulty wire / plug somewhere but said its not causing any problems so did not want to put more hours into it unless I said to do so.. Pressure all checks out and I'm being told that the hydraulics on the older T190's do become loud with hours on the pumps. But theres really nothing they can do about it and they are working as they should. So I guess i'm going to just start pulling all the plugs apart cleaning with lectra clean and throwing some dielectric grease in all of the connectors and be done with it. As far as the loud hydraulics I guess I just have to deal with them till I decide to trade up to the next bigger machine

Not sure what else I could do but would like to change the hydraulic fluid and oils again before winter now that I have some good stuff mixed into the remaining of the old.
