I just installed a 2012 cluster into my 2008 Escalade so I could have the instant MPG, voltage, and oil pressure menus, it's been sitting a while because I overestimated the mileage when I sent it to have the mileage adjusted. Anyway, everything appears to be working great except the oil life and the compass. I'm mainly concerned about the oil life. I held the check mark like to reset it and nothing happened. The Tech 2 still shows the same 73% it was showing on the old cluster. Any ideas?
