Multiple DTCs and goes like hell...

[Mutti82]

Vehicle: Mondeo 2011 2.0 TDCi 140hp with MPS transmission

Conditions of fault: Always when raining or wet roads or stayed overnight in very humid weather. Fault occurs more likely when temp below 10 degrees Celsius but has also come twice when warm and humid summer day. Never at normal cold day, dry and below -10 celsius.

Symptoms: First you feel little "misfire", then dash informs Engine Malfunction, Transmission Limited Function, ESP light on (no ABS light). Then engine sputters hard, runs like only two cylinders working or like brakes trying to prevent skidding, and car bounces like hell when even touching gas pedal. If moving, speed just decreases if trying to accelerate, might be able to maintain speed if trimming with gas very carefully. When pulled over and standing still, engine idles normal, revs normal with P-shift, accelerates/works normal when reversing but immediately bouncing when trying to drive forward and press gas. The faster the speed, the denser the bouncing/sputter.

Permanent or temporary solution: When letting engine idle 5-15min, might just start to work normal and let you drive rest of the trip or just 100m and fault again. Also if dare, just keep driving kangaroo car for 10-15min at 40-50km/h, at some point sputter and bouncing vanishes and car starts to work normal. If have run in those wet conditions but get to dry overnight in dry place, works normal next day.

DTC: Attached picture of DTCs, read yesterday morning, fault occured monday night. There is always also PCM P062E, ABS U0401 and sometimes also TCM P1719 at the moment of fault but had no chance to save them with laptop Forscan, those had gone away after staying overnight and car working fine again. That B113D is permanent code, won't erase, my car doesn't have sunroof.

Live values: ABS sensors normal and synced with transmission VSS. No EGR error between actual and commanded. No ESP/ABS events adding to counter when bouncing. Boost normal. MAF normal. 

Done so far: Changed MAP. Disconnected MAF when fault on, no changes. Ford dealer electrician inspected and electrically loaded engine wire looms for 5h. Changed PCM (it's cover had opened 2 years ago and signs of damp in every pin). Changed turbo (loud whistle, intermittent lowboost/overboost dtc, suspected freezing/sticking, turbo vanes WERE bent and cracked badly, but didn't seem to fix issue).
 

WHAT CAN YOU MAKE OF ALL THIS? Any ideas of cause? Anyone had same kind of issue with any Ford model? Three different Ford dealer workshops and Ford Finland head engineer have now tried to figure out for nearly three years what's going on, with obviously not even a clue. Car has fault that paralyzes it in highway speeds when extremely dangerous weathers etc, and is not suitable for traffic. Do I have any lawful rights towards Ford or salesman in this type of case? Though I bought it from used cars dealer little bit over three years ago and propably salesman has no responsibility anymore. Symptoms started 4 months after deal and I had three months guarantee from him.

And if you have Ford specialist in your friends or know good ones, please share this with them for opinions. :)

Forgot to mention two intermittent symptom:

Stereo panel won't lit up randomly when you press power on. You can hear radio and control it from Convers+. This is also happening only when for example stayed overnight in cold humid conditions. So could this point issue being inside dash...? Where is the "crossroad" of all CAN-network, if I have understood right.

Also randomly "distance to empty" counter resets to 0km and begins to rise slowly when driving. This happening also only in humid conditions, today made it twice.
