If you just visually "eye-balled" the procedure, that's likely where the timing imprecision was introduced which is being noted by the ECU.
No just looked at the marks!
I sent the car to a local garage for a new timing belt and water pump. Got it back last night to which he stated timing had been out. All seemed Ok with car on homeward journey, however on start this morning it was a little rough on idle but balanced itself out within a few seconds. No fault codes showing but I think I'll run measuring blocks again and maybe someone can reassess the data?
