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
