Car Parts Price Matrix

Compare car parts prices across Autodoc, Mister-Auto and kfzteile24 in a single run. Give it one or more part categories, and it returns one row per part per retailer that carries it, matched on manufacturer part number (MPN), EAN barcode, or OEM cross-reference number — with the cheapest source and the price spread flagged on every matched row.

This actor does not scrape a website itself. It runs our own Autodoc, Mister-Auto and kfzteile24 scrapers in parallel, joins what comes back by part-number identifier, and builds the comparison matrix from the results.

Why use this actor?

Mechanics, independent garages and parts resellers all face the same problem: the same branded part — a Brembo brake disc, a Bosch oil filter — is listed at different prices across every parts retailer, and reconciling that by hand means opening three tabs and matching part numbers yourself. This actor does the fan-out and the matching in one call and returns a flat table you can sort straight to the widest price gaps.

What it returns

Each row in the output is one part at one source. Parts found at two or more sources are flagged matched: true with a price spread; parts found at only one source still get a row (matched: false) so nothing is silently dropped.

Real output from a cloud-verified run (see Matching logic below for the full match-rate numbers). This ATE brake disc (MPN 24.0112-0169.1) turned up at all three sources — note Mister-Auto sells it as a pair (packQty: 2) while the other two sell it as a single disc, and pricePerUnit (not the raw listed price) is what the spread is computed on:

Use cases

• Independent mechanics and garages sourcing the cheapest supplier for a specific branded part before ordering.
• Parts resellers doing arbitrage — buy where a part is cheapest, resell or fit at the going rate.
• Procurement teams at repair chains tracking part costs across their approved suppliers.
• Marketplace and catalog builders who need part prices matched to a manufacturer part number rather than a fuzzy product-name guess.

How to scrape and compare car parts prices across European retailers

1. Add one or more entries to Part categories (queries). Each entry needs a query or URL per source in that source's own language — an Autodoc category URL (German/French/etc. storefront), a Mister-Auto search term (French), and a kfzteile24 search term (German). None of the three sites take a literal part-number search reliably across languages, so a shared category (e.g. "brake discs") is what puts the same parts in front of all three sources.
2. Choose which Sources to include. Leave all three selected for the full matrix.
3. Set Max Items Per Source to control how many candidate parts each source contributes per category. Autodoc fetches a detail page per product to get OEM/EAN data, so this source is the slowest and the main cost driver — see Limitations.
4. Run the actor. All selected sources are queried in parallel per category, so adding sources doesn't multiply run time.
5. Open the dataset. Sort or filter on matched: true to see only parts confirmed across 2+ sources, then sort by priceSpreadPct descending to find the widest gaps.
6. Use partNumberType to judge match confidence: mpn and ean are exact-SKU matches; oem is a weaker vehicle-fitment match (see Matching logic).

Input

Field	Type	Description
queries	array	Part categories to compare. Each entry: label, autodocCategoryUrl, misterAutoQuery, kfzteile24Query. Defaults to a brake-discs category if left empty. Max 10 entries.
sources	array	Which of the three sources to include (autodoc, misterauto, kfzteile24). Empty means all.
maxItemsPerSource	integer	Max candidate parts considered per source per category (1-50, default 20).
timeoutPerSourceSecs	integer	Max seconds to wait for each source scraper before treating it as failed (60-900, default 300).
proxyConfiguration	object	Proxy settings passed through to the kfzteile24 child scraper only. Autodoc uses its own Bright Data setup; Mister-Auto needs no proxy.

Matching logic

Parts are matched across sources in three tiers, tried in order:

1. MPN (manufacturer part number) — the exact aftermarket SKU as printed on the part, separators stripped and uppercased (09.9772.11 → 09977211). Two listings sharing an MPN are the same manufactured product. This is the primary match and covers the large majority of matches, since Autodoc, Mister-Auto and kfzteile24 all expose it (kfzteile24 under the field name sku, which follows the same "manufacturer part number as printed" convention).
2. EAN barcode — also exact, used when MPN is missing on one side.
3. OEM cross-reference number — used only as a last resort, for parts with neither MPN nor EAN. This is deliberately the weakest tier: an OEM number identifies a vehicle-fitment slot (e.g. "front brake disc for VW Golf 7"), not a specific manufactured product. Two different aftermarket parts — say an ATE disc and a Brembo disc that both fit the same car — can legitimately share an OEM reference. A matched: true row with partNumberType: "oem" means "these fit the same slot," not necessarily "this is the identical product." Filter to mpn/ean matches for a strict same-SKU comparison.

Note the priority is MPN first, not OEM first: an OEM cross-reference can legitimately point to several different branded parts that all fit the same car, so leading with it risks grouping different products together. MPN is the one identifier that's unique to a single manufactured item, so it's the safer primary key even though it's a narrower match on paper.

Cloud-verified match rate: a real run against a "brake discs" category (all three sources, maxItemsPerSource: 60, Autodoc capped at its usual ~20) returned 140 rows across 122 distinct part numbers, of which 17 (13.9%) matched across 2+ sources — including one part found at all three. Match rate depends heavily on how much the sources' catalogues actually overlap for the category and sample size queried; see Limitations.

Norauto is not included

Norauto's own scraper output has no manufacturer part number, EAN or OEM field at all — just name, brand, price and rating. There is nothing to join on, so including it would mean either silently falling back to fuzzy name matching (which this actor deliberately avoids, unlike the grocery price matrix) or listing Norauto rows that can never be marked matched: true. It's left out until Norauto exposes a part-number field on its product listings.

FAQ

Does this actor scrape the retailer websites itself? No. It calls our own Autodoc, Mister-Auto and kfzteile24 scrapers and combines their output. Each of those actors is also available separately on the Store.

Why can't I just search by a literal part number? None of the three underlying sources reliably support that across languages through this actor. Autodoc has no keyword search at all — only category browsing. Mister-Auto and kfzteile24 take a native-language search term against their own index. Point all three at the same part category (e.g. brake discs) instead, and let the part-number join do the matching.

Why does Autodoc take longer than the other two sources? Autodoc's MPN/EAN/OEM data only exists on the product detail page, so this actor asks it to fetch one detail page per product (fetchDetails: true). Mister-Auto and kfzteile24 return everything from a single listing/search response. Budget more time and a slightly higher timeoutPerSourceSecs when Autodoc is included.

What does matched: false mean? This source's version of the part wasn't found at any other selected source in this run. It's still a real result — just not (yet) confirmed elsewhere. It doesn't mean the part is exclusive to that retailer, only that this run didn't find a matching part number elsewhere.

How is priceSpreadPct calculated? (priceMax - priceMin) / priceMin * 100 across whichever sources carry the matched part number, restricted to sources reporting the same currency (currency is never converted). It's null when only one source has the part, or when the matched sources report different currencies.

Do I need my own Bright Data key or proxy? No. Autodoc's Bright Data Web Unlocker key is configured on that actor itself. Proxy for kfzteile24 is optional (its listing pages have no anti-bot wall); Mister-Auto needs no proxy at all.

Cost estimate

This actor is priced per result at $0.005 per row plus a $0.01 run-start fee — see the Store pricing tab for the current numbers. A single category query with all three sources at the default maxItemsPerSource (12; Autodoc capped at 20 regardless) typically returns 30-90 rows, so budget roughly $0.15-0.50 per category on a first run. Autodoc is the priciest source per result: each of its rows costs one extra Bright Data Web Unlocker request on top of this actor's own per-result price, so keep maxItemsPerSource proportionate to how many parts you actually need matched rather than maxing it out by default.

Limitations

• Match rate depends on how much category overlap the three sources actually carry for a given part type — some categories will have a higher matched-vs-unmatched ratio than others. Every unmatched row is still returned, so you can judge coverage directly from the matched field rather than trusting a blanket claim.
• Autodoc is the slowest and priciest source in this matrix: each of its results costs one detail-page fetch through Bright Data Web Unlocker on top of Autodoc's own listed per-result price. Keep maxItemsPerSource proportionate to how many parts you actually need matched.
• A run's usage cost only settles once the run reports SUCCEEDED — reading a partial/in-progress dataset will show a cost far below the final total.
• Norauto is excluded (see above). Coverage is limited to Autodoc, Mister-Auto and kfzteile24 for now.
• Prices reflect each source's standard online price at the time of the run and can change without notice.
