Fuels Temperature sensor

[StevieRay]

Hi matey, so it was the dpf sensor no 2, had most of the electrics/wiring changed on warranty including a brand new ecu but apparently (what a surprise) someone in opel made an error and the display message is being screwed up. Not cool about removing the dpf though, I gathered by now it's a poor engineering feature on the car but keep in mind it's there for a reason, don't keep the car running in an underground garage etc.

Hi, I'm new here meaning that my comments were coming in a bit late, they had to be approved.

Thanks for the reply. I'm not happy with DPF removal, I regret it very much. However it was painful to have regens almost every 10 miles. When the filter was removed, it appeared normal, not completely clogged with particles. This leads to conclusion that ECU thought the filter was full, most likely due to incorrect DPF sensors.

Unfortunately now is too late for me, I already removed the DPF, but got this P0181 in the process. 

So basically in your case, the P0181 disappeared when the DPF sensor 2 was replaced? Because my friend had experience with another Astra J coming to his garage, with the same issue, and this one has everything original, no DPF removed. It could be that this one has DPF sensor issue as well.

I'm only guessing, I've searched on internet to find any P0181-related issues on 1.7CDTI Astra J but this is the only one I found.
