Cheers, Marc, yep, expected to be so. I have seen some on fleaBay for less than £20.
Whar worries me is the 'clock spring' comment earlier in this thread by "Xantia"!
Tomorrow or Sunday I will be more aware of what has happened. If you look at the instructions on removing and refitting it, it mentions an idiot proof location device. Which will always be at 0° in relation to the steering wheel.

If I remember correctly, when the 'clock spring' (on a Xantia, at least) is in the middle (in other words, it has the ability to travel from full lock to full opposite lock) there will be a pair of arrows that line up (one is fixed, the other is linked to the steering action). If it has been turned one full turn in either direction the moveable arrow will be 90 degrees out.

By the way, would this suit?;

Thanks, yes, I am away from my pc, so I can not cross reference anything. But that is very nice to know there is only one for the X7.
I think I have found the calibration method which I will try tomorrow after the tracking has been set.

Hi All,
I now have a steering wheel that is in the correct position to the road wheels, the other rack was assembled incorrectly - to be sorted another day!!
However, I now would Like a little help working out what is wrong - please. #-o
I have a Steering Angle Sensor fault, and this is sending the whole system (and me) crazy!
I have attached a print out of the errors I have, do any of you have any thoughts?

Additional information
  • When I check the output of the SAS by moving the steering wheel either direction the value changes from 0 degrees, surely this means everything is working?
  • Yesterday when I checked the SAS, my Diagbox says the unit is "not calibrated"
  • When trying to calibrate the SAS I get a screen saying either there is a fault with the unit "Fault Linked to the steering wheel angle sensor has been notified by the ECU. Deal with this fault first and start the wheel angle calibration again" or I am doing something I shouldn't while the process is running like moving teh car or steering wheel.
  • Anti-lock Braking System (ABS), or Electronic Stability Program (ESP) says the steering wheel angle is 344.1 degrees, but the steering wheel angle sensor signal fault says the steering wheel angle is 600.7 degrees
  • I have just carried out a full BSI reset, no change.
Replacement part?
As given by the Citroen Service (& Marc) the part number is 4545H8, when I search on Ebay using just 4545H8 I get 41 'hits' one particular seller gives the information below, which ties in with the labels on the photographed parts. I have read somewhere that these units should be decalibrated before being removed, has anyone any experience of fitting a 2nd hand one? I am thinking of buying one just to see if it fixes the faults or to take apart to see what is inside (spring?)
Manufacturer - PSA – Citroen / Peugeot
Part number - BOSCH 0265005486 0 265 005 486 / 9662937380
Vehicle manufacturer part number - 4545H8 / 4545 H8 / 4545.H8
Part numbers of other manufacturers replacements - 9650236180

Thanks

Just wanted to check the alignment Stu:
Align the foolproof "c" of the steering wheel angle sensor (1) with the groove "d" of the steering column (2).
X7 Steering Wheel Angle Sensor B.JPG
And just to confirm:

Calibration is required in the following circumstances:
Removing - refitting: Flywheel angle sensor
Track adjustment
Replacement of the dynamic stability control (ESP) ECU
Replacement of the switch module at the steering wheel
Work carried out on the steering column or mounting

Does it not require you to be driving the car to calibrate it Stu? AFAIK it can't be done stationary.

Here are the Pin Outs - in case you need to check for signal / comms issues:

Have not checked any alignment, because the steering wheel is in line with the wheels, and unless it all does something silly I can not see how the alignment can get wrong, I may get time to check tomorrow afternoon.
The 'Drive in a straight line... for 100 metres' is to ensure the steering wheel is in the correct position they then go on to say the vehicle must be stationary.......taking as much care as possible not to alter the position of the steering wheel' - I done that then marked the position with two straight lines on masking tape from the airbag over steering wheel to cowling.

The symptoms I have are.
  • ESP/ASR faulty
  • Brakes activate for split second when pulling away the first time on each journey
  • Suspension not at its best.
All these issues started when trying to get the steering wheel straight when the dodgy rack was fitted. I think it is the SAS but really would like someone to agree before replacing it.

I agree - it's a new one on me - but the ESP system and the BSI rely on that SAS for a lot of data - so not surprising all the other faults are being thrown up.

Are you sure that 'braking effect' when pulling away isn't the electronic hand brake releasing? It does that on mine (on the manual gearbox) if I don't manually release the handbrake

Yes reading through the printout, the SAS is referred to regularly, very important box of tricks

I am sure it is the system giving me a warning as it happens at about just above 5 mph with the steering on a lock, one corner squats and makes a heavy crunching sound, brake being applied quickly.

Hmmmm definitely not right, we don’t like crunching noises.

I can only surmise that either the unit has been stuffed as a result of the incorrect rack - but has this physically interfered with the SAS? Has it forcefully rotated the SAS (which is mechanical inside) and damaged it?

Or has the SAS remembered any settings from the incorrect rack when it was fitted and is not resetting and relearning now that the new rack is in place?

Maybe it is worth asking Citroen to recalibrate it or asking them if it can be cleared prior to relearning?


but how has this happened?

Re: Steering Rack Leak(?) + Outer Driveshaft Boot

Post by Sloppysod »

I have found some videos of the sensor, and one particularly shows what is in side.......watch the yellow dot on the small wheel at the top right. the large center wheel is the angle and the smaller one is how many time past 0.
Reading on the Peugeot forums, others have had similar issues and I now need to find out how to fix mine. What you see in the video makes sense,

I have two options.
  • Take the steering wheel off, look at the sensor and see if there is an alignment tell tale, and make sure it is right. Apparently some Peugeot sensors have a window where you can see the dot.
  • Disconnect the lower coupling and rotate the steering wheel to the right 2 turns, then see where the car thinks it is.
because
The steering wheel angle range is +/-610 degrees. My diagnostic is saying it is either +344 or +600 which means that the wheel has been rotated between 0.95 & 1.6 turns too far to the right, I am sure I have read somewhere that a minus figure means to the left. Then recheck with the diagnostics
As to how, it could have been me trying to get the steering re-coupled upside down and forgetting where I started, or sensor over travel.

On Diagbox does it read 0 at straight ahead - and can you see it in more than one ECU, and does it read the same? If you turn the wheel lock to lock does the reading go to +/- 600?

I think I'd be tempted to disconnect the steering column down at the footwell, rotate the steering wheel one complete turn to the left, reconnect the column, then retest with Diagbox.
Presumably you could see live data on the SAS, so you could disconnect the column in the footwell, then twiddle the steering wheel until things start to give sensible readings ???
Sadly no longer a C5 owner :(
