2007 Dodge Sprinter 144 diesel
We had some water get on the driver side of the dash, which got into the instrument cluster, then the instrument cluster died. Symptoms; no lights or symbols on instrument cluster, gauges don't move, no solenoid click for turn signal, but vehicle starts and runs, aftermarket radio works, climate control mostly works, except I think it doesn't know the temp. See below.
I have a Scangauge II, got these two codes:
U0155 "Lost Communication with Instrument Panel Control (IPC) Module"
P0072 "Ambient Air Temperature (AAT) Sensor Circuit Low Input"
I did some searches here, and on the internet. I pulled the instrument cluster, found some oxidation on the big chip marked "MB90F394H." I guess that's a / the microcontroller. My son tried to gently clean its contacts with isopropyl alcohol and a clean brush. We got some turn signal indicator lights glowing on the instrument cluster, after we reinstalled it, but the lights were not synchronized with turn signal control, and no other functionality returned. The back cover of the instrument cluster says "Johnson Controls" and "A9064468421". I read about virginizing used instrument clusters, pulling data from EIS and the old cluster, writing it to the new cluster. I don't quite understand it. I bought a used instrument cluster on eBay, with the same part number.

Can one of you please tell me how to successfully replace the dead cluster with the other cluster, and synchronize it? I am in Oakland, California, USA. I found a few local businesses that do instrument cluster repair, or ECU programming, and called one. He seemed like he might not know the details of this Mercedes system, when I mentioned pulling existing odometer data. I'd be willing to buy some tools to do it, if they're cheaper than paying someone. I have a MacBook, not a Windows PC.
