Hi just to let you know I have exactly the same problem with my 2015 custom believe me I am at my wit's end with it, I have changed the injectors map sensor, maf sensor , fuel rail with sensor, pump solinoid, air charge sensor,new inlet manifold, all genuine ford parts I have even had the dpf and egr delete taken out of the ECU and removed the dpf filter and blanked the egr valve , I've had it on a live data run with absolutely no faults but still have this diesel knock witch comes and goes, when I had the dpf system on the van it went into a regen smoked like mad but drove like a dream a quiet as a church mouse hence why I had a dpf deleat done on it but it still has this knocking noise that won't bugger off its had a full ford ECU update believe me I have put every sensor that the van has on it and still no cure, it can't be mechanical as it would be a noise that is constantly there not one that comes and goes I'm thinking this could be a ECU fault as I have pretty much changed everything thing else on it including the turbo but everyone I speak to including the transit specialists say they have never had a faulty ECU I'm at a loss with mine and have given up throwing time and money at it , hope you have more luck than I have and would be interesting to see if you ever find a cure for this gremlin!
