## Important limits

- Troubleshooting is AI-assisted guidance, not a confirmed diagnosis or substitute for professional inspection.
- diesel.parts does not sell parts, process orders, or provide checkout. Purchases take place on seller websites.
- Listing prices may come from indexed search results rather than live seller quotes. Price provenance is labeled.
- No returned listing does not mean a seller is out of stock; users can visit every searched seller's website.
- Manufacturer, condition, pack quantity, availability, and fitment must be checked with the seller. Unknown details are not guarantees.
- Shipping, taxes, and core charges are not included in the comparison.
- diesel.parts is not described here as an AI consulting agency. No staff credentials, review ratings, customer totals, or ROI claims are asserted.
