I have tested the temp sensor bank 1 at the connector, and measures 210 ohms and rises to 350 when the engine is warm.
The other side of the temp computer measure 5 volts and when shorted is reported with code, which suggests is ok.
What can cause a high temp bank 1 even when the engine is cold.
I have cleared the fault but both DPF and glow flashing light come back.
I have replaced DPF and the sensor PO546, and now run out of ideas.

Welcome to VWAF

Could you tell us the engine? What was the car scanned with, was it VCDS?
