Quick Answer
What is TecDoc certification for EGR suppliers? TecDoc is a standardized automotive parts database used across Europe for parts identification and OE cross-referencing. TecDoc-certified EGR suppliers must provide complete OE cross-reference data, dimensional specifications, and application listings. The database covers 6,000+ vehicle models and 4.5 million parts, serving 700+ distributors in 38 countries.
Tecdoc (TecAlliance) is the automotive aftermarket's largest parts data catalog. For EGR valve buyers, a supplier's presence with correct OE cross-references is a key quality indicator.
What is Tecdoc?
- 7+ million articles from 1,100+ suppliers
- 500,000+ vehicle type links
- OE cross-reference data
- Product attributes (dimensions, specs, images)
- Vehicle linkage (which vehicles each part fits)
Why Tecdoc matters for buyers
For European distribution, Tecdoc is how customers find your parts:
- Workshops use Tecdoc-based systems to look up parts
- Distributors import data into ERP/e-commerce
- Insurance assessors use it for repair estimates
A supplier not in Tecdoc is invisible to the European aftermarket.
How to verify OE cross-references
- Get OE number from the vehicle (stamped on housing or dealer EPC)
- Look up in Tecdoc — verify aftermarket part is listed as match
- Cross-check with supplier's own catalog
- Verify vehicle fitment — specific models, engine codes, years
- Check for superseded OE numbers — good suppliers track changes
Data quality red flags
| Red flag | What it means |
|---|---|
| Not in Tecdoc | No verified data; cross-references unverified |
| OE numbers without vehicle linkage | Likely copied, not validated |
| Single OE number per part | Most valves supersede 2-5 OE numbers |
| No product image | Supplier hasn't invested in catalog data |
| No dimensions/weight | Cannot verify fitment without inspection |
| "Universal" listings | EGR valves are never universal |
Our entire valve catalog (118+ SKUs) and cooler catalog (61 SKUs) are Tecdoc-listed.

Frequently asked questions
Is Tecdoc listing free?
No. Annual fee typically EUR 2,000-5,000 for a small catalog.
Can I trust cross-references not in Tecdoc?
Verify independently against vehicle manufacturer's EPC or dealer parts counter.
How often is Tecdoc updated?
Quarterly. A supplier that hasn't updated in 12+ months is a data-quality concern.
Does Tecdoc guarantee quality?
No. It verifies data exists and is structured. Quality must be verified separately through IATF certification.
