I had been driving my car and while driving or making a turn even in park but the gear shift in "drive" the car would shut down. The red battery light would appear on the dash display. If I have the radio or the conditioning on they would both continue to run. I would put the gear shift into "Park" and would turn the key in the ignition off. After sitting for about 5 seconds I would restart the car and it would return to its normal functioning.
I explained to the mechanic what the problem was and he suggested I take it back to the dealer to have the throttle body checked. After doing diagnostic testing on the vehicle the dealer's mechanic concluded that it was indeed the throttle body that went bad. They suggested I have my battery changed since its charge could have been effected by the throttle body. The throttle body replacement was covered under my state emissions warranty therefore, I did not have to forfeit $700+ dollars.
Ive got an 02 jetta vr6 with a 2.8l 24v dohc with automatic transmission, my throttle body over heats and wont alow my car to start and I have shifting problems when shifting into 3rd gear and at times, it slips out of 3rd into a neutral like stage. Ive got a little over 178,000 miles on my jetta. Ive changed every sensor under the hood and even my throttle body and still have the same problems.
