Gentlemen - many thanks for your quick responses. All three plugs back in so assume if one had been missing the fault would have re-appeared immediately the car was started for the first time and the power steering would not have functioned. No I have not re-calibrated the steering angle sensor since I was not aware this was required, but I did check for a sensor fault and there was none, however would appreciate the calibration procedure if there is one. The fault code does reference the servomotor so assumed '611' would be in this area.
Here's a thought.......................
When mine went wrong I got all sorts of advice, one of which was to try turning the steering from lock to lock as apparently this can reset the system. I did this before I changed the EPS motor, but for the sake of five minutes of your time it's worth a go.

Gentlemen, again thanks for all the replies. I will try the lock-to-lock and recalibration route but need some advice on the re-calibration procedure, How do I do it ? . I hope that with the many excellent suggestions coming in someone in my predicament in the future may gain some benefit these options.

Tried the car again today, and playing around the car does exhibit slightly different symptoms to those discovered yesterday. I can start the car fault light on, turn off ignition and then restart fault light off, it seems the situation is not permanent but intermittent, I'me sure there is something in the EPS ECU that is not quite right, it only occurs when power is turned on (ignition on) so very intermittent. Tried lock-to-lock but the symptoms are still the same. Will try pulling and replacing plugs to see if it is an intermittent connection problem.

bigwinn - that's a very kind offer, I am based very near Winchester which regretfully is a little way from you. My own diagnostic unit (Creator C310+) is a great & inexpensive unit for fault finding and fault clearing but unfortunately does not have the sophistication of inpa. I am going to contact ECU Testing this afternoon and relay my symptoms to see whether they encountered this effect before. I know they bench tested the unit but if the fault was intermittent it may not have shown up in their initial testing and may have needed more than one attempt to bring the problem forward. Again thanks for your offer but will stay in touch either way.
Coincidentally I've just been contacted by a chap in Sussex who has a problem with his EPS. Sometimes when he turns the car on it works and other times it doesn't. Whichever state it starts in, it stays like that. ie. It doesn't fail during a journey if it started up ok.portculisz4 said:
Sounds like a similar issue to yours.
I'll be honest, he's offered me the car cheap if he doesn't fancy fixing it himself but I'd like an idea of what I'm taking on.
If ECU Testing can give you an answer I'd be keen to know please.

Gentlemen, just an update on the situation since you have all been so helpful. Problem still there and awaiting response back from ECU Testing. The fault does still occur when first starting the car but can sometimes be cleared by turning the engine off and then on again (may have to do this once or twice). The problem never re-occurs whilst driving the car, it seems to be an initialisation problem in the EPS when first applying power (12v) to it. This should be a useful clue if the technicians are sufficiently electronically trained and know the workings of the unit, I'me a retired electronics design engineer so such a symptom would be a useful clue to me. Basically the EPS works, it just doesn't fire up in the correct state when first powered up by turning the ignition key on.
That is exactly the symptoms the car I'm getting has. I'm hoping its an easy fix.portculisz4 said:
I wonder if yours had two faults and this one was masked? I know ECUTesting ask you to detail the symptoms. Maybe it happened to fire up ok for them so they wouldn't have known to look for that fault? I hope that's it, as it will make my life simpler. But of course you'll have to go through the whole process again.
