ive had my 2002 new beetle coming up on 2 years now. I love her. In the last month I have been having some rough times though. My check engine light was the first to come on,next is my engine coolant light is always blue, next two were the airbag light and my abs light. I had my car scanned and it came up with a C02 sensor (not quite sure) and a sensor for my abs. I didn't think much of it and continued on with my vehicle. My boyfriend had recently put in an aftermarket stereo deck (the only thing aftermarket so far in my car)and about a month later I was driving down the road and out of no where my emergency break light comes on and my car dies, I tried to turn it back on and no luck just all my dash lights flicker and my car clicks-I got a jump and it worked fine for about another month. This month has been the worst for my car. it has died probably 10 times on me all with the same thing happening. One of the last times it died I got a jump and it died a few hours later, got another jump and it died 5 minutes after, got another jump and it wouldent even turn the car on, I replaced the battery and it worked fine for me the last week until today. I was drving and the same thing happens everytime- my lights dim and my stereo turns off, my acceleration is not like usual, my emergency break light comes on and dings at me then my car just dies. Today my oil light was flashing as well but my car has oil, engine coolant all of that.. I left it to sit for a few hours went back to it and it started up now its dead down the street again, what should I do? My alternator tested fine as well.. is there anything else I can check myself before getting it looked at? Sorry for so much to read but thank you if you did read it !
