Hello all,
About a week ago my daughter was driving our 2000 Jetta that has the VR6 engine (about 50k miles). The serpentine belt broke/came off. She saw a battery warning lamp come on but did not see the temp guage move past the mid range.
The car was towed and the belt replaced along with the belt tighter. The car now idles ok but runs rough and backfires when you start to accelerate. This is so bad that is not driveable. Computers codes do not show any problems - any ideas?
