Depolution system faulty 307 hdi

[JeremyPetrovic]

Hi

I got message on car computer: “Depolution ststem faulty”. I went to Peugeot and they quote $1600 to fix problem. Eventually, problem is differential pressure sensor, it has to be replaced.
I bought the sensor Peugeot advised. But I have problem to locate it. Someone on google advised it should be behind battery.
I removed battery but sensor behind it is not the one I bought following Peugeot reference. I attached two pictures.
Is sensor I bought wrong one or sensor behind battery is not differential pressure sensor?
Please help.

That is the dps the new one is modified
Your research needs to be more detailed google can tell you the earth is flat and licking tyre rubber cures cancer also if your pipes to the dpf are toast that may be the cost of 1600
