Exhaust Gas Temperature Sensor 4 Bank 1 error

[dtr]

Hi,

I just wanted to ask the opinion if you would just try a new sensor and hope it all goes back to normal like it once was a very long time ago or would you say we have DPF terminal issue (and the fix?). Last few months it was easily drinking 20-30% more diesel than before.

When driving a long distance a coil would come up and the display says Engine Fault Workshop. Nothing really happens in terms of driveability or anything else that I could tell and on restart the message is gone. This remains logged and clears with VCDS until the next time:

VCDS shows ash Vol 180ml and carbon was just 5.3 while the last regen was over 1200km before. That doesn't make sense to me. Standing reg won't activate no matter what.

So new sensor or DPF internal fault?
