Volkswagen EPC Catalog:
part number by VIN
To sell Volkswagen parts without guessing, the professional flow starts at the brand's electronic parts catalog (EPC): that is where the exact number each VIN carries lives, with diagrams and supersessions. Here is how it works at Volkswagen, and how to close the loop all the way to the quote from your own inventory.
Volkswagen's EPC
Volkswagen's dealer network uses ETKA (the VW group catalog: Volkswagen, SEAT, Audi, Škoda): the official breakdown per vehicle, with the diagrams for each group and the history of number replacements (supersessions). The platform prefix (1K0, 5C0, 2Q0…) is the VW counter's quick tell: it says which chassis family the part comes from before you even open the catalog.

Volkswagen numbers follow a three-block format like 1K0-698-151: the first characters identify the vehicle platform. At the counter you will see them every day on the Jetta, Vento, Tiguan, Virtus and Saveiro: they are the brand's highest-volume models for parts.
Finding the part by VIN
- The VIN (17 characters) sits at the base of the windshield and on the driver's door frame; it encodes plant, year, engine and trim.
- The EPC filters the breakdown down to THAT vehicle: on a model with two engines and several brake or suspension variants, the VIN removes the ambiguity that "model and year" leaves behind.
- Supersession matters: if the customer brings the number from the old box, it may have been replaced — the catalog shows the chain down to the current number.
From the original number to your quote
The EPC answers "which number is it". The counter lives off the next question: how much does it cost and do I have it? You almost never sell the dealer number: you sell your documented aftermarket equivalent. Quoting a set of Jetta brake pads means crossing the original number against your catalog, checking stock and putting the answer together before the shop across the street does.
💡 With an AI quoting tool, that chain runs on its own: the customer sends the VIN or the Volkswagen number over WhatsApp and the answer comes back with YOUR SKU, YOUR price and YOUR stock in seconds. The EPC brings the precision; the quoting tool brings the speed.

Frequently asked questions
Where do I look up Volkswagen's parts catalog?
The dealer network uses ETKA (the VW group catalog: Volkswagen, SEAT, Audi, Škoda). Outside the network, an aftermarket counter works from its own catalog of documented applications and equivalents: the key is not access to the EPC but having the cross from the original number to what you DO sell.
Can I find a Volkswagen part number from the VIN alone?
Yes: the VIN pins down plant, year, engine and trim, and with documented applications (in the EPC or in a catalog with ACES-style data) you reach the exact number without guessing between trims.
What do I do if the Volkswagen number the customer brings no longer exists?
It was almost certainly replaced (a supersession): you follow the chain to the current number and cross from there to the equivalent in your inventory. Answering 'I do not carry it' without checking the chain is leaving the sale on the table.
