So I got the following error pop up today and have discovered its the Error Code P2455 - DPF Pressure sensor. I have cleared the system and will keep an eye on it to see if it pops back up.   Just getting myself ready in case it needs replacing.   Should I replace with original or OEM if OEM which brand?   Any idea of the cost of the part?   I have the 1.6tdi any idea of the location?   Is it a case of just unplug and plug the new one in?   Thanks
