I had the check eng light come on today. It had come on about a week and a half ago then went off a few hours later. Now it is staying on, so did the key dance & came back with DCT Code P 0521
which I have found to be;
P0521 Oil Pressure Switch Rationality
per a net search

So sent an email to my shop that does repairs for my warranty work.
Let you know what comes of it.
