A puzzler for you all

[RPWC]

My mother owns a Pug 107 ,07 plate, 2 years ago, it lost half its mileage . It had about 29000 in spring 2014,next bill the mileage was 14000. How can this have happened? She has had to have the harness that runs down the steering column replaced twice,as each time the wheel was turned the horn went off. Now the power steering warning light is on,and the power is not working. Any ideas on these anyone?

no idea Rich, but I want to drive to the garage she uses

There's this on another website regarding the power steering on the 107:

Power steering problems

Problem: You may find that the power steering stops working, or the steering can feel very heavy at times. This is caused by a problem with the power steering pump.

Solution: Strangely enough, as a temporary solution, a hard knock with a heavy hammer can get it going again, but the best thing to do is to get a replacement pump fitted.

I didn't even realise the 107/C1/Aygo even had power steering! They're not exactly massive cars and I'm surprised they even need it...

Mind you, the steering is exceptionally light it firms up nicely at speed so whatever they did, they got it more or less right..

I love how that states the bloomin' obvious

Tapping it with a hammer is good. Just like we used to do with recalcitrant starter motors in the olden days!

Surely not all have power steering? My daughters 07 reg is extremely heavy to drive. Did it get fitted to later models if its there at all?

90% sure they all have PAS.

It is an electric column (motor on column) and a 'manual' type steering rack. It will not feel *that* much heavier if it failed as you' re not having to compress any hydraulics, the only 'drag' is the motor really and if I remember correctly that's on a one way clutch anyway (so you can't 'drive' the motor from the column, if that makes sense)

These models do not have a BSi as such, they are not plexed. Regarding the mileage I'd expect it to be just held in the instrument panel itself not in the ECU if its based on earlier Toyota designs...

[RPWC]

Its definitely electronic ps, not hydraulic,the mileage you say held in the ecu, so a computer diagnostic machine would read the ACTUAL mileage,rather than what's displayed on the odometer?

Yes but it might be the same as (as far as I know) its only in one place unlike other models with a BSi where its in a couple of places.

Another manufacturer stores the miles in the panel and the ECU too, and diag on that model shows the ECU miles not the panel. Its normally the same or within +/- 50 miles which is accepted.

Well the car is now i the garage,and the mechanic has told her he hopes it can be repaired,rather than replaced,as if it's the latter,the whole column needs replacing,which could lead to a bill in to 4 figures. She has decided once its fixed,to sell it,she has lost confidence in it now,and at 83 rarely drives it anyway.
Its lucky to get two short runs a week these days,so I kind of persuaded her that now would be the time to consider giving up driving.
The amount of money spent on repairs this last two years, would pay for a lot of taxi fares, its all been caused through lack of use,I tried to tell her to just move it back and forward inhere parking space a couple of times a week, but it fell on deaf ears.

Having checked the MOT history of the car,I would estimate the current mileage to be 33-34000. The last correct milesge was in May 2013,at MOT time, the mileage then was 28000,the previous year was 23000, so basing it on an approximate annual mileage of 5000, that would give my estimated figure. Between 2014 and 2015,it only did about 300,yes three HUNDRED, miles,as she wasn't using it.
Having spoken with the garage that are dealing with the repairs,they told me the steering had been fine since they have had it,and that if the fault reappeared, the column would have to come off and be sent to a companion Rochester Kent for recon.
The last problem was the horn was sounding continuously all night, not intermittent like an alarm ,just constant
Some serious electrical gremlins with this car.

Well after having the car to an auto electrician, their diagnostic machine couldn't read the faults,so I took it to the nearest Peugeot dealer,typically mid journey, the ps light went out and the power sterring started working again. Got the result of the diag test today, and it turns out its the power steering control module or ps ecu that's faulty. The cost to replace? discounted to £764 Needless to say, no way are we paying that, I have found a local electronic power steering repair specialist,who can repair the fault for £125, if I remove the unit from the car. So that is the next step, I collect the car on Saturday,and it will have a full written report of the result from the diagnostic check, not badly priced at £58. If the unit turns out to be unrepairable, there are plenty second hand on eBay for £65/70,or previously recon units for £176

[CitroJim]

Interesting. So is this a common fault?

That the units are so readily available and repair specialists exist suggests it may be.

Good to know the more economical solutions when this problem occurs and it's much appreciated you have shared it with us on here...

[RPWC]

Next step is removing the thing,its right at the back of the engine bay,passenger side,held on with 4 10mm bolts,not very accessible. Diagnostic report showed clean bill of health ,but only list a (possible ) fault with p/s ecu.
No fault codes,so I think I will take it off and get it tested anyway,see what it brings up.

[CitroJim]

Watching this with great interest Rich

Hope it is more accessible than it looks These things often are...

[RPWC]

I had a look and its a case of remove battery, take out bolts holding main e c u in place, move it to one side, then this gives access to the p/s control unit, four 10mm bolts and the large clip removed ,and off it comes, might get a chance to do it next weekend. Will keep you posted.
