I picked up a used 2007 Beetle 2.5 with 125,000 on it. Runs good most of the time. If it idles for 10 minutes or more and gets hot it will start missing and will eventually cut off. After cooling it will start and run fine. There seems to be a problem with something heating up and malfunctioning. I have replaced the Mass Flow and O2 sensors. Will plug coils malfunction when they get hot. Codes show misfires and lean bank. If I park it hot, it will not crank till it cools down. Seems heat is the common element. Actually runs great when it is cool and going down the road.Tries to crank, just misfires to much to catch up.
