Hey guys! I recently bought a 2002 Beetle Turbo S 1.8T and love it. I just don't know much about the maintenance history. Last week out of the blue I have a solid blue coolant light now and sometimes the oil light will flash when I come to a stop. I did some researching on the site and found its most likely the coolant temperature sensor, so I went to Oreilly's bought one, and replaced it. I then reset the battery and the blue light remains on even with 30+ minutes of driving and the engine is definitely warmed up. Then I looked on this site again and found that I might need a VW temperature sensor, so I got another one from the dealer and replaced it as well. I even unplugged the battery just in case. I still have a blue coolant light all the time.... It is not blinking or any other color, coolant level looks to be right on the max line. I even added just a bit and it did not change anything. Ideas?
