Financing early triggers – interest rates?

Hello all, first of all the little history: August 2019 relatively young Golf 7 GTI financed. 900€ paid, 12k Euro run on four years. Well, by changing jobs, promotion etc I have been able to travel so well in the last months that I can trigger my car prematurely in November. What I could already read out from my contract is a precaution compensation, which VW would like to have. This is to be counted with one percent (1%) of the still open loan amount. However, I could not find: Will the interest, which is charged over the four years, be partly refunded to me (or charged)? Before I call the VW Bank now, I wanted to ask for advice here, maybe one of you already has behind it. Greetings
