MASK0N Posted June 27, 2023 Share Posted June 27, 2023 Hello. Can someone tell me the exact differences between CSUD and CNHA engines? Would it be possible to replace a CSUD engine with CNHA ? A6 C7 2014 Thank you very much. Quote Link to comment Share on other sites More sharing options...
Steve Q Posted June 27, 2023 Share Posted June 27, 2023 I appreciate my A6 is a lot older but similar rules should apply. You might find the instrument cluster and ECU will need coding to the new engine Quote Link to comment Share on other sites More sharing options...
