 We bought our 03 Beetle with the 1.8L with about 50,000 miles on it. Within weeks it had an engine light on. I have battled the engine light, among other things, ever since. We changed an injector and a coil pack on the number 2 cylinder because of a persistent miss. This was after diagnosis of codes would not narrow the problem down. Immediately following it began cranking hard on start and not starting until the second attempt. First code said crankshaft sensor so we replaced that. Had to replace camshaft sensor thereafter to fix the problem. Next it threw a coolant system code so we replaced the ECT sensor. After that the thermostat. This car was a reliability nightmare. Never ever again.
