Hi

This has no doubt been asked before. I've googled this and get bits of threads here and there but nothing of use. Just wondering if it is possible that from a OEM serial number if it's possible to see all the cars that part was used on?

In my case the OEM number im interested in is 9837905080

Any help appreciated.

Didn't you ask the same thing in March? https://www.pistonheads.com/gassing/topic.asp?h=0&...

Good point. I kinda did, I'd forgot all about that.

I later established that the KYB's I thought might fit are not compatible.

Now i'm looking at it a bit different. If i can find another car which uses the same part no, and they have an OEM alternative via Bilstein/ Monroe etc then I presume they should work on my car too.

My car is a DS9 225hp petrol. I have checked the Peugeot 508 225hp petrol which is it's closest relative and that has a different part number.

Is it common generally that one part number is just used on one car? In this day and age with merged companies across groups like Stellantis, VAG I'd expect there to be a lot of parts sharing. Like if Stellantis for instance use the same infotainment system across models to save cash I'd presume they'd also share a lot more common parts such as suspension.

I was going to have a look but my catalogue doesn't have the DS9 in at all which has totally surprised me!

There could be a very minor difference which you wouldn't even notice in reality, but that would instigate a different part number.

Thanks for looking.

I've searched for the part number in the hope it gives me a list of the cars it fits to no avail. Seems to pop up as a PSA/ OPEL part on a few Eastern European and Turkish websites. One of them had a "the part is for this list of cars" underneath but the fields were blank, the DS9 wasn't even on it.

Bilstein part number for a 508 is bilstein 19-295480
you could just call bilstein and ask for the data you need,
Essentially an OEM will have it's own part number data type for a part for a car. Sometimes this is because it is a model specific part like a piece of trim, but in the case of suspension it'll be because they just want to follow their own PN data type.

Sometimes an OEM may have 2 or more suppliers of the same part, so DS might use both Bilstein and say KONI to supply it's suspension and also they may have 2 part numbers to determine whether the part was fitted on the production line or warranty, aftermarket.

You need to look into the original maker of the part and then view their catalogue. It is true that the same part from bilstein might end up on multiple different models, at various price points, and yes Stellantis and the like will rationalise their parts so that the same part is on all brands. I believe that there has been a project within Stellantis to cover this off, and I think there are some dealer websites that you can search for a part for your car and see the cross reference. Try searching for EUROREPAR.

TECALLIANCE power the data behind autodoc and they are a front end to a multitude of parts suppliers like Bilstein, FEBI, Lemsforder and the like.

I have been able to use my parts knowledge to source Hyundai i20N front discs from a Kia Ceed GT, which are half the price, so I understand what you are trying to do.

Can't help on the original part but frankly its a minefield.

You have parts that have been updated (ie superseded) but are functionally identical (and so would fit)...then you have parts that have been changed and wouldn't (because *other* parts on the vehicle have also changed and in many cases they've been fitted to the same model, some times even in the same MY!

Then you have parts that are dimensionally different but would still fit.

You have the aftermarket where they tend to only care about _some_ of the dimensions and they don't always have full details of all the versions[1].

Take as an example brake discs for my bike. OEM ones are NLA, aftermarket ones are the same fitment as the newer model which are also of a different style.

Except on further investigation the aftermarket (and later model) discs are 5mm thick where the originals are 4.5mm... and you can get the dimensionally identical (but different style) OEM discs brand new still.

Equally brake calipers. The only difference (apart from the mounting bracket) between the brake calipers on mine and next model is the bleed screw (and so the body is mildly different), all the pistons, pads, pins, bolts etc are identical. But later models only sell the seals as a "set" of seal and dust seal while the one for mine are sold individually (and are more expensive as a result).

Turns out that there is the one model in the middle where all the individual parts for the caliper are the same as the later model with the exception of the seals and the seals are separate... So the cheaper set" of seals off the much later will fit my bike even though they're not listed. It however took extrapolation of these facts rather than a lookup to find this out.

Another example is the shocks/springs on my car. Apparently there are something like 28 combinations depending on engine/trim. Yet the aftermarket sells *one* version!

[1] Again on my bike they changed the shock length and spring rate part way through the model run. Some aftermarket shock manufacturers list one model of shock for all years when at best there is two and worst three!

You can for any Toyota/Lexus part number via a certain site, but I don't know for other marques.

I've been through something similar, KYB parts too.

Self levelling rear shocker failed on my Forester, new shocks are special order dealer only at prices think of a number and tack a row of zeros on, no one makes an aftermarket self leveller, nor even the correct exhaust for an XT.
Finding the right uprated springs and shocks would have been a nightmare, but luckily there's an indy mechanic on the Subaru forum who's done this conversion himself and was kind enough to give the relevant part numbers, hence what would have been well over £1000 for a new pair of rear shocks only proved to be a £250 DIY replacement with uprated springs and standard shocks, all made in Japan, correct ride height and better handling to boot.
Without such specialist part knowledge i'd have been stumped.

Have you posted on make specific forums, maybe someone else has been there before you, most likely an indy mechanic.

It is possible to do this on Peugeot Servicebox. Put in the vin, do the search then take the vin out with the little button next to the search and it will list all of the vehicles using that part. I did it all the time in the three years i worked there (2019-22) I think you can do it just by searching the part number too without a VIN selected. I think you'd have to do the same thing on a Citroen dealers system to see the list of their models unless you call a parts hub that have access to all the PSA brands?

Another thing to bear in mind is that even if a vehicle is very similar to another one and the parts look superficially identical, the cars themselves may have been set up or specified very differently from the factory. The part may be interchangeable, but it might not be correct.

I'm thinking something like a Skoda Karoq and a SEAT Ateca here. They're built on the same assembly line and the body is near-identical. Suspension parts for one will fit the other, but they're not the same. The Ateca is set up much firmer from the factory.

On the other hand, you'd probably find minor bits on a Bugatti Chiron that are the same as on a Golf, so it's worth investigating.

True, springs are the best example, can vary from model to model as well depending on axle loads due to engine weight etc.

Having a rummage, I get the feeling this is the OP?

https://frenchcarforum.co.uk/forum/viewtopic.php?t...

They're pretty good at parts number bingo across there, and I note that the OEM number is unique to the DS9.

Thanks for all the comments guys, very much appreciated. Even the posts which aren't directly relevant help too. I havent got time at the moment to investigate fully but will do so in due course, probably at the wkend.

I've asked on another forum about the PSA servicebox alternatives with someone who has access to one. I'll see what they come back with.

I was thinking about this today. The 208/2008 and some others had a load of TSBs regarding shocks. If you look up the suspension section for your VIN and go to the section with TSBs and extra information , there is a table of part numbers and the ones that replaced them. Plus Peugeot have a habit of printing numbers on parts that aren't actual part numbers and these extra documents often list these numbers along side the actual part numbers you can order.

This can be why its hard to find definitive answers on replacements.

Id talk to a few dealerships and find one with a knowledgeable parts guy biggrin

Thanks for thinking about this again P2KKA, much appreciated.

The dealer has mentioned this to me before, that there is a comments box with replacements for cars where a fix has been done somewhere else on the same model range, it works and then they do this when new issues arise at other locations.

The issue I have is the DS9 is so rare with just over 100 ever sold in the UK and a lot of these have the adaptive dampers that mine doesn't have, so the dealer claims there is nothing there and I suppose this is understandable.

As you have experience of the PSA servicebox I want to run something past you for your thoughts, just to ask if you ever encountered it in your experience?

The suspension is noisy back and front so I wondered if some wheel well sound deadening would perhaps improve the situation. I took off the plastic surrounds, dodomatted and closed cell foamed them. Road noise seems to have dropped a bit but the noisy suspension remains. When i took off the rear's wheels I took a pic and posted on the frenchcarforum, a very helpful guy on there with access to the PSA servicebox said the bumpstops I have should not be on the car, i was amazed.

Apparently what seems quite early in the production run in July 2020 they changed over the bumpstops to something superior.....in terms of cost, I later found out they fit the upgraded one's to the C5 Aircross. My car built in june 2021, 11 months later still had the old versions on. This is a summary of what he said....


Your build date code of 16293 = 18 June 2021.

DS9 vehicles built up to 26th July 2020 (RPO 15966), had the rubber rebound fitted, (part: 9824164780) which is what is printed on your vehicle.

DS9 vehicles built from 27th July 2020 (RPO 15967) onwards have a different part called a buffer (part: 9834333080). This is what you should have according to official parts.

There's a significant price difference and the later part is called a 'Buffer', costing £126.08. The Rebound Block you have is priced £46.13.


In your experience was this a common occurrence? I just wonder what other incorrect parts may be fitted too, and if this is causing my issues at the front end?

...and I should have added the car is with the dealer at the moment having these fitted, I am very intrugued to see what difference they'll make when I get it back.

I do wonder how often these bump stops are hit? I have no suspension knowledge but eyeballing the situation with the wheel back on there only seemed to be about 10mm between the existing buffer and the trailing arm. I don't know if it's meant to be this way or not. I thought buffers/ bumpstops were there as a last resort in the event of overexertion to protect the car but here with only 10mm gap I guess it must have been hitting them a fair amount.

Just an observation, I have no idea how the replacement part seems to cost over £100 everywhere!!!! there seems nothing to them.

This is what I had on the car

Just got a reply from the Frenchcarforum, the guy says this:

"There's actually only 2 TSBs for the suspension for your specific vehicle showing (the others will be for the other types of suspension system fitted and not applicable), one concerns the 'Policy for the replacement of the front or rear shocks according to the mileage of the vehicle' and the other concerns a 'Squeaking, clicking or grinding noise coming from the upper section of the front suspension'.

There's no replacement parts showing except for the rear shock fixing screw, the rear suspension link, and non -strut parts like the front hub carrier bush, so he may be looking at parts for another vehicle / model."

Any suggeestions P2KKA?
