Yes, it is often possible to display oil temperature on a 2017 Jetta using VCDS, however, the availability depends on the specific trim level and the existing instrument cluster configuration. Even if the setting appears to be “ON” in VCDS, there might be other factors preventing the display from showing. A comprehensive controller channel map can help in troubleshooting.

2.1. Initial Steps to Enable Oil Temperature Display

1. Select Instrument Module: In VCDS, select the “Instrument” module at address hex17.
2. Security Access: Go to “Security Access – 16” and enter the code 20103.
3. Adaptation: Select “Adaptation – 10”.
4. Search for Oil Temperature Setting: Enter “IDE00295” in the search box and select “IDE00295-Oil temperature display”.
5. Change Setting to “On”: If the setting is not already “On,” change it to “On”.

2.2. Troubleshooting When the Setting is Already “On”

If the oil temperature display is not showing even after confirming the setting is “On” in VCDS, consider these troubleshooting steps:

• Check for Compatibility: Ensure that your instrument cluster supports the oil temperature display feature. Some base models may not have the necessary hardware.
• Review Controller Channel Map: Analyze the complete controller channel map for the instrument module (address 17) to identify any conflicting settings or dependencies.
• Look for Related Adaptations: Investigate other adaptation channels that might influence the oil temperature display.
• Consider Cluster Coding: In some cases, the instrument cluster might require specific coding to enable the oil temperature display. This coding could involve changing a byte or bit within the cluster’s coding string.

2.3. Example of Controller Channel Map Entries

The following is an excerpt from a controller channel map that might be relevant when troubleshooting the oil temperature display:

Parameter	Value
IDE00295-Oil temperature display	On
IDE00346-MAS02201-Units adjusted-Temperature	Degrees Celsius
ENG105834-dimming_characteristic_curve_adjustment_gauge-Y5	64

This table shows the oil temperature display set to “On” and the temperature units set to Celsius, along with a guage setting. This suggests that the display should be active and showing the correct temperature format. If it’s still not working, the issue might lie elsewhere, such as a faulty temperature sensor or a more complex coding issue.

3. What Could Prevent the Oil Temperature Display from Working?

Several factors can prevent the oil temperature display from functioning correctly, even after enabling it through VCDS. These can range from hardware limitations to software conflicts.
