A few days after visiting the dealer for an oil change with the 19's, idrive started intermittently throwing "AWD, DSC and ABS malfunction" after driving 10 miles, but not every day. As a test I put the stock 225/40/18 - 255/35/18 setup on and have gone 1000 miles without any codes.

My question is did the dealer do something to the programming? I want to put my 19's back on, but the code is worrying me.
Your sizing with the 19's is ok. I don't know what the dealer could have done to cause those errors. I'd say it's not related to the 19 inch wheels and tires.
