How to Troubleshoot a Volkswagen Jetta


VCDS
1. Check if your Volkswagen Jetta has an onboard diagnostic system that is compatible with the Volkswagen Car Diagnostic System (VCDS). According to Ross-Tech, a diagnostic software manufacturer for European automobiles, VCDS will work with most Volkswagen and Audi models sold worldwide 1994 through 2010.
2. Activate the VCDS software on your computer. VCDS software only works on computers running Windows and that have serial or USB outlets.
3. Locate the VCDS cord outlet on your Volkswagen Jetta. The exact location will vary by model, but it should be under the front hood. If you have trouble finding it, consult your owners manual.
4. Follow the program instructions to receive a coded report on your cars diagnostics. Check what the codes mean in the programs instruction manual to determine what is the problem with your Jetta.
OBD-II
5. Find the on-board diagnostic (OBD) outlet on your Jetta. The OBD-II system has been installed in every model of Jetta since 1996 -- previous models used the OBD-I system. The exact location of the OBD-II outlet will vary by model, but it should be under the front hood. If you have trouble finding it, consult your owners manual.
6. Connect an OBD-II scanner to your car via the devices cord.
7. Turn the scanner on. Write down the codes it gives in the diagnostic report and check what the codes mean in the OBD-IIs instruction manual to determine which component is not functioning correctly in your Jetta.
