The 17705 Ross-Tech Wiki is a vital resource for anyone working with Volkswagen Auto Group (VAG) vehicles. This guide dives deep into the 17705 fault code, providing expert insights, troubleshooting tips, and practical advice for car owners, repair shop managers, and automotive technicians alike.

Decoding the Infamous 17705 Code: What Does It Mean?

The 17705 fault code, often encountered when using a Ross-Tech VCDS (Vag-Com Diagnostic System), typically indicates a “Pressure Drop between Turbo and Throttle Valve (check D.V.!).” This essentially means there’s a leak somewhere in the pressurized air system between your turbocharger and the throttle body. Think of it like a punctured tire – the air escapes before it can do its job.

Common Causes of the 17705 Fault Code

Several components can contribute to this pressure drop. The most frequent culprits include a faulty diverter valve (DV), cracked or leaking hoses, a damaged intercooler, or even a problem with the turbocharger itself. Pinpointing the exact source requires a systematic approach.

• Diverter Valve (DV): This valve is responsible for releasing excess pressure when the throttle closes. A malfunctioning DV can cause leaks, leading to the 17705 code.
• Hoses: Any cracks or loose connections in the hoses carrying pressurized air can cause pressure loss. Inspecting these thoroughly is crucial.
• Intercooler: This component cools the compressed air from the turbocharger. Leaks in the intercooler or its associated hoses can trigger the 17705 code.
• Turbocharger: In some cases, the turbocharger itself might be the source of the leak, though this is less common.

Troubleshooting 17705 Ross-Tech Wiki: A Step-by-Step Guide

Using your Ross-Tech VCDS and the information available on the 17705 Ross-Tech Wiki, you can effectively diagnose and resolve this issue. Follow these steps:

1. Scan for Fault Codes: Connect your VCDS and scan for fault codes. Ensure the 17705 code is present.
2. Visual Inspection: Carefully inspect all hoses and connections in the intake system for any visible damage or leaks.
3. Diverter Valve Test: Test the diverter valve using the VCDS output tests. This can help determine if the DV is functioning correctly.
4. Pressure Test: Perform a pressure test on the intake system to pinpoint any leaks. This involves pressurizing the system and listening for escaping air.
5. Component Replacement: Once the faulty component is identified, replace it with a high-quality part.
