What code reader did you use? Some generic ones only give the emission related ones and not manufacturer specific

Interesting. Code comes on while slowing down. Hmm. Virtually impossible to tell without a code. Turbo over lost (sticky actuator) maybe? But could be literally anything, literally anything at all.

Does the car go into limp mode by the way please sir.

Not sure how comprehensive the snapon readers are but forscan will give more information as it has all the Ford specific codes also you can plot live data while fault is actually active to see whatís amiss
