The electric power steering pump in our 2006 Ford Focus 1.8 TDCi 5 Door Hatchback (this is a UK car) has failed and I plan to replace this myself. The part in question looks like this:
According to the local Ford garage, when this part is replaced they have to read some data from a control unit on the broken pump then copy it to the new "blank pump". The chap on the phone euphemistically called it a "suck and blow" part.
This sounded quite unlikely, and has the smell of making the job sound more complex than it actually is thus ensuring Ford get my business.
Upon making further enquiries elsewhere, I am told that the pump is not in fact re-programmed in any way, but that the "re-programming" is simply to reset the fault light in the engine management system once the part is replaced.
Can anyone shed any light on the real truth of the matter here?
