Stock Problems/IssuesDiscussions related to warranty related issues and repairs, or other problems with the OEM parts and software for MINI Cooper (R50), Cabrio (R52), and Cooper S (R53) MINIs.
On my new to me 2010 Mini, I've found that it has stored codes of P1339, 0303, 0304. Am I correct in my assumption that I need to replace both Camshaft Sensors? Or is there a test that can determine which one is bad?
