You assume correctly - "5.1.1.1.2 Suspension" to be precise. I thought suspension meant shock absorbers but, as I say, I know little of mechanics.

I did ask the CT guy what was required and he said to repair or replace the amortisseurs. I didn't know they could be repaired as such tbh, but I admit to knowing little about such things.


Well, if that's what he said then that's what he said.
Her's all it says in the CT items:
5.1.1.1.2. Dissymétrie importante
Défaut(s) inclus : Différence d'efficacité supérieure à 30 % constatée sur un même essieu.

A bit of a 'catch-all' really.

Just seems a bit odd if it's the amortisseurs that he didn't fail it under either of the items I mentioned in my first post.

Many thanks for the info Chancer. I didn't appreciate that the test was quite so contentious, nor that other factors (like tyres) can play a part. Tbh, I'm inclined to ignore it (as the bounce test is ok, and it drives ok) and see what they say on the next CT.

At this point, I think the noise (maybe cv joint) is more of a concern.

Zombywoof. Thats because he can only fail it on them if they are visually defective, bushes worn, piston rod rusted, visual leaks etc, they may have exhibited none of these signs or even have been cleaned up in the past.

Even new ones can exhibit 30% different damping characteristics between a pair, on adjustable dampers many people fall into the trap of adjusting them say 4 clicks clockwise whereas in fact one may need 5 clicks just to equal the damping force of the other at the start position.

FWIW the dynamic shake test is a very good one but as they dont have the baseline figures for the vehicle they are not able to say that under a certain damping force they are inefficient which leads to the crazy situation that if you have a shot damper then you drill a hole in its partner, drain away the fluid, clean it up and you have a matched pair of completely non functional dampers which will pass the CT.

True. Was he advice contradictory then? That is to say, would replacing the shocks not correct the imbalance? I don't know.

There is always the possibility that the tester is not familiar with all the parameters influencing the result of the test.

Indeed. Also, I have a recollection of reading a notice in the CT place that said something like 'we are not mechanics' which I took to mean don't ask us to fix anything!

But perhaps, more broadly, it meant that they only follow rules, they only test but don't (necessarily) understand much more beyond that. That'd make sense to me, in a legal context.

For reference there is a comprehensive list of the CT categories and what they mean here:

Quote, Chancer, "Thats because he can only fail it on them if they are visually defective,...".

Quote, Chancer, "...if you have a shot damper then you drill a hole in its partner, drain away the fluid, clean it up and you have a matched pair of completely non functional dampers which will pass the CT."

Both of the above comments are incorrect. See my first post on this thread, ref. 5.1.1.1.1 , 'amortisseurs inefficaces'.
The CT wouldn't be a lot of good if it didn't include testing the performance of the shocks.

The point of my second post was that as the tester told the OP to replace his shocks, then it follows that the tester must think that they're shot, in which case he could - or should - have failed it on the aforementioned 5.1.1.1.1.
The fact that he didn't suggests that the problem may be something else.

To be fair to him, he was responding to my question, a leading question perhaps. I wrongly equated 'suspension problem' as 'shock absorber problem' and asked if changing or repairing would resolve.

I apologise once again to you Zombywoof for my "incorrect" postings.

I will try and refrain from posting again regarding Controle Techniques, headlight alignment or vehicle engineering in general.

No need to get snippy.

Base lines or no the shake test will instantly reveal a non functional shock absorber and presenting a vehicle with a pair of those, thereby producing 100% symmetry, will get you a contra visite for sure.

Why the vehicle in question did not get one for a 58% dissymetry I really don't know, only the tester can tell you that.

Some Scudos have air suspension which is controlled electronically.

Air suspension :shock: I did double check the vehicle in question to make sure it wasnt a Citroen.

In that case I owe you an apology Cardi, my comments regarding the soapy water were unwarranted. :oops:
