Technical power steering advice - accident near miss

As I have said Fiat service have told me what is wrong. The car was taken to the fiat dealership, the service dept gave it a through going over and used the computer and they said it is failure of that part of the electronic control unit (ECU) which controls the steering; and it needs to be replaced. Not the battery. The a whole unit has to be replaced because of failure of the electric component in the ECU which has the sensors that detect the motion and torque of the steering column, and then that bit of the ECU computer applies assistive torque via steering column. In my car that electronic senor isn’t working properly or consistently. It doesn’t seem possible to replace this particular electronic component as it is in a sealed. This is what I was told by the garage.


It cost almost £40 for this diagnostic testing. But obviously the engineers got it all wrong and all I need is a new battery.

Not that this was the original point, I was just asking for people experiences with Fiat who may have had the same problem as per the old thread.

Thanks anyway

People are just trying to give you a hand sorting out your issue as cheaply as possible. Sure it could be the power steering unit and by the sounds of it probably is...... but the batteries can also cause similar issues so people were just trying to help.

If you don't want people to try and help you do things as cheaply as possible then don't post on discussion forums full of helpful people.......

"Engineers" is a somewhat misleading term here. Computer screen readers would be a better term. In my experience the vast bulk of "engineers" these days simply replace whatever the computer says is broken. On many occasions this tuns out to be cobblers.

For this particular fault I too would first try a known good battery. I've had power steering issues also resolved with a good charge-up.

as stated there is more to diagnostics than just reading a computer screen, example - what if one of the connector terminals was loose and you paid for a new steering column but all it needed was the terminals tightened...of course after disturbing the connector the garage and you think it's fixed but it's not and a few weeks or months later the steering light comes on?

the ECU which has the sensors that detect the motion and torque of the steering column,

Incorrect, why would the 'sensors' be inside the ECU?

and then that bit of the ECU computer applies assistive torque via steering column.

You mean the motor?

Seriously I would get a second opinion infact no I would do as I said earlier and get a reconditioned full unit for a third of the price.

Out of interest I done a panda a few days back, customer fearing a massive bill and going to trade in car, pleading poverty, xmas coming etc etc, it was the battery,£24!

I wouldn't bother Maxi.

OP let us know how you get on with Fiat, I doubt you'll get far due to the age of the car. I do hope it is the £700 ecu and not a £50 battery, at least it means the £40 for diagnostics would have been worth while, and correct, and I could be proven wrong then.

It would unfortunately seem you, just like most 'fitters' at a garage would rather go by what a computer screen says, than old fashioned manual diagnostics.

By the way, the computer would have said that torque sensor is not feeding back the correct information, and it is this causing the EPS to shut down. It wont have told them what is faulty with the sensor, ie the supply to the sensor, supply from the sensor or possibly the sensor itself.

Peace out.

To the OP, PLEASE listen to this, T is a proper technician and knows what he's talking about. Have the battery swapped out for a known good one and if that doesn't solve the issue, get a recon unit on the cheap.

BBA Reman seem reputable and all the people on here who have had power steering units replaced by them have never had a recurrence of the issue.
