Ulysee Diesel PTC Heater Problem
Summary of the thread
A 2022 Fiat Ulysee diesel exhibited poor performance during cold starts, stored an error code, and showed increased fuel consumption. Diagnostics suggested a defective PTC heater as the cause. A similar case confirmed that the electric auxiliary heater was the issue, leading to a workshop visit where the heater was replaced, resolving the problem.

The error code indicates an electrical fault related to the heating element. Was the resolution in your case definitively traced to the electric auxiliary heater, or were there other contributing factors?

For me, the PTC heater was indeed the culprit. Given the error code and symptoms, I suggest a workshop visit for confirmation, but it does sound awfully familiar.

I appreciate your insight. The workshop confirmed the defective heater. The repair, costing approximately 350€, has resolved the issue. Thank you for pointing me in the right direction!

ULYSEE

I have a Ulysee and have seen similar symptoms. Poor running when cold and higher fuel consumption could point to a faulty auxiliary heater. Is the error code pointing to an electrical fault in the HVAC system?
