Poor obd on 2007 vw Jetta for engine speed sensor. 3vwef71k57m117381 is the VIN of the car, recently the egnine begin to stall/die soon after starting, unable to hold the idle speed but there was no mil/check engine light, upon several atempts it used to run fine it continued for several weeks. One fine day my wife and 2. 5 month baby were driving on I-75 south to detroit downtown and car stopped in the middle of the freeway- it just stopped for no reason no mil or check engine light even after these events. It came back up running again after she was able to start the enigne again. On the same day while she was driving back from the office it stopped while getting out of the parking lot again no check engine light. It was the scariest day, we towed the car back home even though it was starting again due to the fact that there was something seriously wrong with the vehicle. On 25th March 2011 I started the car in the morning then I saw the check engine light on dash board for the first time, and dropped it off at fox automotive dealer in rochester hills mi. Where they were not curtious in dealing with this problem, and found the engine speed sensor [crank angle sensor] was found broken, replacement of the same seem to have resolved the issue. However the main concern is the obd did not work when it saw several misfires and engine speed issues, which could have prevented my wife and baby not to drive to work on freeway, this is a serious concern. It is essential that vw dealer should also address such serious issues with some concern and importance where they did not give any oppertunity for me to drop off the vehicle for repair the same day I towed the vehicle back from my wifes office, after few days of gap I was able to drop the vehicle where they worked on it after few days of wait time, they even recommended me to drive back the car with check engine light if I need vehicle the same day or early. I request the USA govt to look into this matter immediately.
