Transit Connect 1.8 diesel 2010, Diagnose Challenge

[KnutUH]

Hi,

I bought the Connect with an ABS error, ordered a cable and used Forscan to help me figure out that I needed to replace front right wheel bearing with a damaged ABS tone ring. So far so good, but after a while I got Instrument Cluster drop-outs and later limp mode. Now I have found a broken wire to the smart charging altenator. I found helpful info from Tdci-Peter in the Focus forum, tried to back-probe the accelerator pedal and decided to get a new pedal. That worked for 5 minutes. What would be your next step? (see my DTC log below)
