Aruggaber,
How many miles are on your Jetta and what engine is it? If you don't know you can give me the vin and I'll check. The reason I'm asking is because some models had problems with their converter. Also is there any other faults in memory other than the faulty catalytic converter fault. Certain fueling problems can cause the engine computer to think the converter is faulty when it really isn't.
Thanks for using Bestwebmechanic.com I await your answers.
