My FordPass app now shows 21N03 instead of 21B10. Did anybody else’s app change? What is the difference? They performed 21B10 a couple of weeks ago, but it still has the cold start rattle. I’m scheduled to take it in September 13th for them to look at it again.
it happens when slightly under load around 20-30mph. The trans feels like its in too high of a gear because it drops down to around 1100rpms with a slight bit of throttle, if I increase that it eventually goes away when the vehicle reaches 1500rpms or down shifts. For example the other day I was in 6th gear at 22mph and 1100rpms going up a slight grade... this is with the max tow package (shorter gearing).Can you describe this shudder? When does it happen? Does it goes away with more throttle?

The FSA I had performed 2 weeks ago was actually supposed to remedy the original reflash that screwed up my vehicle to begin with (my exp didn't do this prior to the cam phaser reflash 21B10 that did absolutely nothing in terms of remedying the rattle).
I can't confirm the cam phasers are revised, but I can confirm mine still rattles lol. I believe mine is wastegate though at this point.
Are you sure its not just relearning your driving style? 21N08 re flashes to factory as built.Mine still shudders, just SLIGHTLY less frequent than before
