Quick answer
A Tesla referral link, often called a referral code, associates your visit to Tesla's website with a participating account. Tesla shows whether a benefit applies on its landing page and during checkout. Use the link before ordering; retroactive attribution is not guaranteed.
Before ordering
Attribution must happen in time under the current terms. Factors may include the first qualifying purchase, region, vehicle, account, promotion period, and exclusions. What Tesla displays remains decisive.
Buyer benefit
The benefit and conditions displayed by Tesla on its landing page and during checkout are what count. Also check the official German program page and the details during checkout.
Referrer benefit
The operator's personal referral link would be clearly labeled as advertising.
Important limits
Tesla may decline attribution or participation under its terms. Its official page contains statements about using individual credits that require interpretation; DukDrive does not resolve uncertainty by guessing.
