Hi Scotty I drive a 2008 Volkswagen GTI 2.0 TSI CCTA I recently added too much oil without realizing it. I broke down I had my car towed to a shop the mechanic said it was the alternator so I had that replaced along with all spark plugs coil packs and battery. I only live a few blocks from the shop so I drove to my house. on my way home my car started blowing Blue smoke out of the exhaust. I drove it the last few blocks to my house and parked the car. Thinking back  I had realized I had overfilled it with oil I guess the mechanics overlooked this since there was no mention of it to me.  since then I have drained it to the correct amount of oil I would like to know if I'm supposed to change the sensors and oil filter as well? every time I drive every so often I'll get the low pressure and that loud beeping sound from the dashboard please help please and thank you! Ps I did hook up my scanner and there wasn't any codes found but I'm not sure if it's because I only have a cheap scanner
