Suspension sinks on Sundays! C5 X7 that works hard + 206 GTi HDi (and 406 Coupe and 306 HDi). - MattBLancs

For my future reference:

Watched about 8 minutes this morning, looks pretty comprehensive.

Just in case I have missed it - the issue with the forum's access to Service Box never did get resolved, did it? No replacement for the parts requests thread?

(Would like to confirm part numbers / dimensions for the replacement clutch: online sources seem to suggest 240mm diameter items, I've not yet chucked the old clutch and flywheel from my blue 308 SW clutch replacement (2016, same as its replacement) and that measures 250mm diameter

I used ai for your thread query here's the result

ServiceBox Forum Access Status
The forum VIN/parts-request threads remain dead and unresolved. After Stellantis locked ServiceBox behind paid trader/subscription accounts and strict VAT checks, free public access was permanently revoked. Forums (such as French Car Forum and PeugeotForums) were forced to shut down their lookup threads, and no official replacement service has been established.
​Clutch Dimensions: 240mm vs. 250mm
​Your physical measurement of 250mm on the removed factory clutch is spot-on.

Spec Detail2.0 BlueHDi (DW10FD / DW10FC) OEM SetupAftermarket / Cross-Reference Confusion
Disc Diameter250mm240mm
Spline / Hub21 teeth (25 \times 21.4\text{ mm} profile)18 or 26 teeth (varies by 1.6L or SMF conversions)
Flywheel TypeDual-Mass Flywheel (DMF)Often listed for Single-Mass (SMF) conversion kits

Why online databases show 240mm:
​Engine Grouping: Online parts catalogs (e.g., TecDoc/Autodoc) frequently bundle parts across the whole 308 (T9) line. The 1.6 BlueHDi / 1.6 THP engines utilize 230mm or 240mm clutch setups.
​Conversion Kits: Aftermarket single-mass flywheel (SMF / Kit4P) conversion options downsize the friction plate to 240mm.
​OEM Specification: Factory 2.0 BlueHDi 150/180 manual setups (DW10 engines) paired with the ML6C gearbox use the 250mm assembly (e.g., Valeo FullPack DMF 837431 / 832404).
​Trust your physical measurement over online catalog filters—you'll want to order a 250mm DMF kit.

Looks like a trust your gut type of thing here
Hope that shines some light on it for you

Ah good ol' AI!!

Ah well, I've used a tape measure before lad, not my first rodeo when it comes to "read the numbers to confirm the measurements"

Oh it's a good crop of jibberish the machine has assembled there!
Sudden mention of single mass flywheel conversions!? The spline dimensions need to match on single mass type (sprung) clutch or you'll have real fun and games when come to try and put the gearbox back on!!

Ouch, throw poor Autodoc under the bus! "It's their fault my data is wrong" nice try AI!

Spot in Husky, I've done exactly that.

Indeed tonight I've "put my money where my mouth is" to the tune of £475

Spoiler: show

eBay, Parts in Motion:

Clutch, pressure plate, concentric release bearing/slave cylinder and DMF

Interestingly Autodoc does not list clutch kit for my new 308. It also thinks it's 180 bhp (which I think only Automatics got that output)
AI alto mentions a 180bhp manual too

Last MOT had advisory for CV boot, so shopping for them next.

Oh that's conscientious, I appreciate this message:

Reg to check compatibility

You may or may not get some amusement out of my son and I playing about getting the red liquid out the adblue tank

[Huskyxantia]

Normally the gut is right , think your be ok with that kit and ai does love to make a tangled ball of wool out of its own work .

[Huskyxantia]

Removed the red stuff , is the car ok , meaning running right ?

It's only run home so far (down the M65, would have been 30 minute drive if not for getting stuck in a queue of folks rubbernecking a crash (cars cleared onto hard shoulder, but gawping rather than getting going = sat in a queue!) so about an hour, no issues to report...

...other than slipping clutch if give it heavy throttle.

So kept the miles off it, so far. Qashqai is still here (and I am still yet to be paid out by insurance) so that has done the work commute this week.

May I suggest online automotive parts, I ordered a set of front springs for my C8. They contacted me a day later saying they wouldn't fit and I needed different ones. Good checking on their behalf or I would have had springs for a C8 Corvette.

These folks?

Ah, not come across them, I'll keep them in mind - thanks

They do list a clutch kit, LUK for my car and pleased to see it's 250mm as expected:
https://www.onlineautomotive.co.uk/peug ... -and-parts
Seems a good chunk more expensive (£556.49 for clutch, pressure plate and release bearing/slave cylinder - Vs £475 for the same plus DMF I've just bought. (Valeo branded)

Are they one of these endless different discount places, like Autodoc?

[mickthemaverick]

Interestingly they are my other online parts source if Parts in Motion can't supply for any reason. I tend to buy most service parts online but I still use my long term motor factor, Midnight Motors in Watford, for OEM nparts.

Might be of use to you Matt

Email from ebay .
We’re introducing Fitment Plus Auto from 15 September 2026 to help buyers find the right vehicle parts more easily, improving the shopping experience. It’ll automatically add compatible information to your eligible UK Parts & Accessories listings where appropriate. Your live listings will be updated automatically, so there’s nothing you need to do.

How it works
1.

Fitment Plus Auto checks the item’s brand and Manufacturer Part Number (MPN) against our fitment database

2.

When a match is found, it automatically adds the compatible vehicle information to your listing, though any information you’ve previously entered remains unchanged

For eligible listings that already have fitment information included, Fitment Plus Auto may add missing or updated compatible vehicle information to help improve coverage.

[MattBLancs]

Thanks Husky - that's interesting. Will be interesting to see how it gets on with Peugeot/Citroen where you can need RPO / build date info to pin down a match sometimes!

Whatever eBay's reg number based part compatibility checker uses thinks I bought a match, but:

Latest news: reg number supplied to seller, they've confirmed they don't think it's a fit, have offered an alternative and have given me a refund.
