Which car brands and parts catalog systems does WebAutoCats.com cover?
WebAutoCats.com is a web resource that links to genuine auto parts catalogs organized by manufacturer-specific catalog systems. Based on the site's own description, it covers four catalog systems — ETK, ETKA, PET, and EPC — spanning European and North American brands. If you are looking for a factory parts diagram or part number for one of the brands listed below, this site is organized to point you to the correct catalog system for that brand.
Catalog systems and the brands they cover
The site groups its coverage by the OEM catalog platform each manufacturer uses, not by brand alphabetically. That matters because the same system can serve several brands under one corporate group.
| Catalog system | Brands covered |
|---|---|
| ETK | BMW, Mini, Rolls-Royce |
| ETKA | Audi, Seat, Skoda, Volkswagen |
| PET | Porsche |
| EPC | Mercedes, Smart, Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac, Saab, Saturn |
ETK — BMW Group
ETK is the electronic parts catalog used for BMW Group vehicles. On WebAutoCats.com it is listed as covering BMW, Mini, and Rolls-Royce. If your vehicle is from any of these three marques, ETK is the system to look under.
ETKA — Volkswagen Group
ETKA covers the Volkswagen Group's volume brands: Audi, Seat, Skoda, and Volkswagen. Note that this grouping is by corporate platform, so a Skoda and an Audi part search both route through ETKA even though the brands are marketed separately.
PET — Porsche
Porsche is listed separately under PET rather than being folded into the Volkswagen Group entry, even though Porsche is part of that group. If you need a Porsche parts catalog, look for PET specifically.
EPC — Mercedes and North American brands
EPC is the broadest category on the site. It covers Mercedes and Smart, plus a long list of North American brands: Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac, Saab, and Saturn. Several of these are discontinued marques (Hummer, Oldsmobile, Pontiac, Saturn), which is worth knowing if you are searching for parts on an older vehicle — the catalog coverage exists, but the brand itself may no longer be in production.
How to use this to find your catalog
- Identify your vehicle's brand.
- Match the brand to its catalog system using the table above.
- Look for that catalog system on WebAutoCats.com.
The expected result is that you land on the correct OEM catalog platform for your brand rather than searching across unrelated systems. The main snag is corporate grouping: if you assume every German brand sits under one system, you will look in the wrong place — Porsche (PET) and the Volkswagen Group brands (ETKA) are separated, and BMW Group brands (ETK) are separate again.
What this site is and is not
WebAutoCats.com describes itself as a miscellaneous web resource for discovery, directories, archives, web culture, or useful tools, with genuine auto parts catalogs as its listed content. The description does not state pricing, account requirements, or access conditions for the catalogs, so treat availability and any login or payment terms as something to confirm on the site itself rather than assumed.
