Finding OEM alternatives

[500x]

Hi

I just have a generic question that I hope someone can help with?

My understanding is for common cars there are a number of OEM alternatives available.

My situation is a bit different. I have a rare DS9 and no OEM's are listed.......however i do know "Manufacturer part no. (MPN): 98388843 80" and this is apparently Vauxhall/ PSA, https://www.online-parts.co.uk/vauxhall-spare-part... so there is a likelihood this is fitted to other cars in the Stellantis range. Might be say a Vauxhall Insignia?

Can I find out what Vauxhall/ PSA this was also used on and then look at OEM's available for that model........and then assume compatibility?

Should do.

I do this a lot with my Lexus. Look for the Lexus part number then the corresponding Toyota one. Then look for aftermarket parts using the Toyota part number.

It’s the cheapest way of getting the same part, all Lexus stuff is marked up massively.

Wow, a DS 9 - one for the 'cars you never knew existed' thread! Photo?

The latest-gen Insignia launched in March 2017, which is the same month that PSA announced it would take Vauxhall off GM's hands. Thus I doubt there would be many parts shared between PSA cars and any Insignia.

The DS 9 appears to use PSA's EMP2 platform, you can see platform-mates here https://en.wikipedia.org/wiki/EMP2_platform - I guess the Pug 508 may be the closest more common partner. Your car could share parts more widely than its platform-mates, but those are the most likely to have most in common.

I don't know where to look and appreciate any help I can get. I know it's closest relations but expect there is a bit more to it than that.

It's the 225hp 1.6 non hybrid version.

I think you can ignore the vauxhall (well, really, Opel) connection. The last opels will have been developed years before.

The closest car I can find that shares bits is the Peugeot 508 1.6 PureTech (225PS), for example https://www.autodoc.co.uk/spares/peugeot/508/508-s...

As to the question of assumed compatibility, ABSOLUTELY NOT.

Even the same part number from the same maker can be a different part.
Aftermarket OE parts can be different specs to those fitted at the factory in a number of ways, but for the sake of example:

• Engine has 180bhp and 225bhp versions.
• From the factory, pistons are either forged or not. 225bhp versions are forged, others not.
• Parts catalog shows pistons from each version are identical numbers.
• Turns out that the replacement parts are always the forged 225bhp version because if you're replacing either type, the forged one will work.

Matching numbers is consequently not necessarily the same actual part, just a part that will do the job.

Hopefully this shows how part numbers matching in a catalogue don't necesarily mean the bits are the same across two different types, it just means that for replacement purposes the bit should work.

Thanks for that.

Clouds the issue even more but I do understand where your coming from.

By the way, https://www.howmanyleft.co.uk/?q=ds9&commit=Se...

From that, it looks like the production run of righthand drive DS9s is on a similar scale to the test+development fleet size for something like a BMW 3er, in the tens or low hundreds.

Rare AF. Hope you enjoy the car

I was aware of this.

At the time of buying last summer there was 70 something in total on there and now i see it's up to 100. Now I can expect the odd dealership would order a new one periodically but what confuses me is my car the Non Phev was discountinued in 2022 yet the number which i specifically remember as 31 has now risen to 39. Maybe the 22 reg stock like mine was not taxed/ registered and didnt count at the time?

I thought i'd got about the very last one of the non PHEV batch, but I did notice the other day motor point has one just like mine, 22 reg, del miles, 24k. It's a lot of car for the money, and the only thing not to like apart from my poor suspension which I'm trying to rectify is the £570 VED

I read a little statement somewhere that showed that the Stellantis UK dealer-group Marshalls had been more or less forced to buy some (eg 1 per site) as demo/showroom cars and had released them back into the market en-masse. It's not uncommon for cars like this to sit unsold for quite a while and the "howmanyleft" site isn't immediate anyway. DVLA's data quality is pretty bad because it's from dealers who on the whole have no interest in accuracy at all; ask 10 of them to register something and you're likely to get 11 variations on how the car should be coded into the system.

If the main thing you're looking for is a change in suspension and you're looking to keep the car for a while, it is probably worth looking aftermarket to something non-specific to the DS9.
Various brands just make generic ranges of shock absorbers (eg. a common brand/spring combination would be bilstein dampers with eibach springs). They make a huge range of sizes (different travel lengths, ride heights, spring rates, damper valving, etc) but if you know the basic mass each has to deal with and what sort of ride quality you're looking for an aftermarket supplier will usually be able to select something to suit that. You can't change the mass or inertia of the car, but you can change things like how soft or hard the car will ride.

If you've a broken damper/shock assembly and don't want to get into the aftermarket, or if you don't want to keep the car long enough to invest the time, money and effort in redoing the part of the car you don't like, then I'd just suggest taking the problem back to Citroen for a direct replacement. It'll obviously cost some beans at that point but you won't be developing your own car either.

Interesting you say that. I bought mine from Marshalls Leicester end of Jul 2023, and the rep said 30 or so we're part of a fleet order that was cancelled and the lease company was a Marshall subsiduary and they were offloading them. I don't think it was quite one a site, I know leicester had 3 at one stage, Scarborough the same, and then there was another site with 2 or 3, cant remember which. I also think a fair few were drip fed to motor point, at first I remember 8 being on the website one Friday, perhaps around May 2023 and then by Monday they'd all gone. That was at £28k. Then a few more were drip fed in 1's and 2's, and the prices gradually came down.

I am looking to keep the car for a while. I have mentioned it to the dealer (car still under warranty) and he's going to see what he can do but I'm not hopeful of resolution here, but it might happen.

I have read a lot about people unhappy with the ride on the old DS5 changing to Bilstein B4's and saying the change is transformational so that would be one route if compatible. perhaps even better would be assuming compatability I could fit the double hydraulic stops off the C5 Aircross. A full set of 4 is only around £300 for parts. https://kyb-europe.com/blog/double-hydraulic-stops...

Valid point made about weight. The C5 Aircross range weighs 1408kg to 1770kg, and my car is in the middle (ish) of this at 1540kg.

I have found the part numbers for my car.....this morning....they are as follows.

Front Suspension Damper, part: 9837905080

Rear Suspension Damper, part: 9837905280

So reverting back to the KYB link I now would like to know if part: 9837905080 part: 9837905280 are comptible with part numbers 3348095 & 3448033.
