Howdy,
I've recently replaced the complete lower suspension arms on my 2011 3.0 HDI wagon. (Also replaced the thermostat housing).
The task went fine, but I now have heavy steering and the front suspension is too high.
Looks like I've stuffed something up......but I can't figure it out.
Can anyone put me out of my misery, with a few clues?
Thanks & regards,
Rhys

Re: C5x7 faults - from lower arm replacement
It's dependent, if you replace it with an original, or other brand.
In the past i replace them from an other brand, then also the car stands to high and it was not possible to adjust it with the diagbox.
I find out, that the part on the arm witch hold the arm of the high sensor was wrong.
Original there is an high different between the two plates.
I hope you understand what I mean. It's about the plates that are bolted on the lower arms and where the arms from the high sensors are connected to.
Greetings,
Kees.

Re: C5x7 faults - from lower arm replacement
Thank you Kees,
I understand the bracket you mean.
The arms were Sasic brand.
In the event the new brackets (on the arms) are incompatible with the original positioning - can't the suspension be re-calibrated through Diagbox to the original heights?

@rhysaccess:
In my case when i had the problem, with the height of the car i find out, that the ones on the new lower arms had the same height between left/right.
So i replaced them with original ones.
Otherwise it's not possible to adjust the height with the diagbox, because there are to much difference in the data from the height sensors.
Greetings,
Kees..
Here you can see, they are the original ones, that the bal head are not at the same height. In my case when i had the problem, with the height of the car i find out, that the ones on the new lower arms had the same height between left/right.

Thanks Kees,
My old arms were thrown out - so I can't use the old brackets.
Can you advise the height differences (Left & right) so I can modify theses replacement brackets to suit?

@Rhys:
As it is more then a year ago, i don't know, but at my car it was the left bracket with was wrong compared with the original one.
But i find out with the diagbox how the value must be.
The diagbox show the height in mm, you must try to get the same value from the left and right height sensor, then you can adjust the height of the car by the diagbox.

Thanks Kees,
Just to be clear - the left perspective means Driver's side on LHD vehicles?

Yes, that's correct.
