P11D7 is a NOX sensor calibration signal problem. I cant help with a P11DC. Sorry.Is there anyway that your code was a P11D7 instead of P11DC? I ask you because I have got this code a couple of times in the last 35K miles. I bought a code reader soon after a couple CEL's right after I bought the CTD to avoid the dealer visits.
