Luk Audi, Seat, Volkswagen, Mercedes Benz, FORD 2004 Parts Catalog

You ever waste an afternoon because the part number on the box didn’t match the one in the aftermarket app? I’ve seen it more times than I can count. That’s why I tell guys starting out: get the OEM catalog. This 2004 LuK RepSetPro parts catalog covers Audi, Seat, Volkswagen, Mercedes Benz, Ford – plus Mazda, Opel, Renault, Vauxhall if your shop handles those too. At 28 pages it’s not a novel, but every page is stamped with factory spec. No guesswork, no third-party reinterpretation. Just the original German engineering data that Luk put together for their clutch systems.

Numerical Listing and Component Breakdown

Two ways to find your part. The catalog starts with a numerical listing (page 20) sorted by LuK order number – no fumbling through alphabet soup. Then the component list on page 24 gives you exploded views and item numbers. If you’re pulling a clutch kit for a 2004 Audi A4, you can cross-reference the part against the Seat or Volkswagen listings to spot shared components. That saves time and inventory mistakes.

Order Code Explained: 8 Digits That Tell the Whole Story

LuK part numbers aren’t random. First digit – product group. Next two – clutch diameter in millimeters. Then a four-digit counting number. Last two – design variation. This catalog decodes the system in the “Explanations” section (pages 4-8 and 25-27). Memorize the pattern and you can ID a Mercedes Benz clutch disc before you pull it off the shelf.

Does This Catalog Cover Flywheels and Slave Cylinders?

Yes, but only for the RepSetPro line – which includes the concentric slave cylinder (CSC). The 2004/2005 edition specifically bundles the central release bearing into each kit. That’s a big deal because CSC failures are common on Ford Focus and Volkswagen models. Having the correct part number from page 20 means you don’t order the wrong bore size.

3 Reasons to Use a Factory Parts Catalog Instead of Aftermarket Lookup

First, aftermarket databases often merge supersessions incorrectly. This catalog shows the original part and any updates in the numerical listing. Second, the order code breakdown is unique to LuK – aftermarket tools strip that detail. Third, the drawings are scaled to the actual geometry, not generic clip-art. If you’re rebuilding a clutch pack on a Mercedes Benz C-Class, you’ll spot the difference between a 240mm and 250mm disc right on the page.

Who Needs This 28-Page Document?

Home garage guys pulling a transmission for the first time – you’ll use it to verify part numbers before ordering. Shop owners – keep it on the bench so your new tech doesn’t put the wrong release bearing in a Seat Leon. Me? I keep a printed copy in the bay for when the network is down and a customer with a Ford Transit is waiting. 28 pages cover a lot of ground.

Source Authenticity: Why This Isn’t a Second-Generation Copy

This is a direct scan of the original 2004 LuK RepSetPro catalog printed by LuK-Aftermarket Service oHG in Langen, Germany. The file includes the TecDoc reference for quarterly updates. If you want aftermarket interpretations, go ahead – but don’t call me when the slave cylinder doesn’t fit.

Can I use this catalog for Mazda or Opel vehicles?

Yes. The catalog includes Mazda (page 11), Opel (page 13), Renault (page 15), and Vauxhall (page 17). Same factory data applies.

What units are the clutch diameters in?

Millimeters. The order code uses two digits for diameter – e.g., 24 means 240 mm. You’ll need to convert to inches if that’s your preference.

Is this the same as a repair manual?

No. This is a parts catalog. It lists components and part numbers. You still need a service manual for torque specs and removal procedures. See related catalogs below for that.

Does the catalog include torque specs for pressure plate bolts?

No. Parts catalogs don’t list torque values. Get the factory service manual for your specific model. The related LuK repair solution manual may help.
