Car began to stutter and shake like it was running out of gas. Shortly after I had an epc light that would flash on every time I got up to speed and it would start the stuttering sound again. After several costly trips to dealership they discovered it was a coolant migration problem. Where a defective part that VW knows about leaks coolant in to the wire harness. Coolant can migrate throughout all electrical routes throughout the car. This has been a problem since 1998 and VW will not do a recall or reimburse for the work. If you have electrical problems with your VW this is most likely the cause. We have also had problems with taillights blowing very frequently. This can be a cause of coolant migrating through the wires.
