problem #1

Mar 012003

Jetta 4-cyl

  • Automatic transmission
  • miles
My speedometer started bouncing up and down. One second it would register 25mph the next it would register 100mph. It would do that frequently. The fuel gauge acted funny as well. It would move left and right. Finally the speedometer stopped working completely. The fuel gauge works ok now. I have read about what the problem is. The coolant migration system is faulty. The coolant bottle leaks fluid onto the electrical wiring harness which in turn acts as a vacuum and the coolant makes its way all the way to the ECM. After it reaches the ECM it makes all the electrical components act funny. This could be dangerous considering it may be the cause of air bag deployment which I have heard. My wiring harness on my coolant does have coolant on it. Which has stopped my speedometer. Thankfully my airbags haven't blown(yet). Please consider this serious issue. Thank you for your time. ~chad~
