I have a 2012 TDI on road trip the Glow plug first code, I pulled over and did a scan and received the P240f. I cleared the code and proceeded home. A little bit down the road the engine light came on, which resulted in code P2478. I have pictures but I am not allowed to post attachments at this time. I have done some physical troubleshooting. I decided to change the oil while this was ongoing. When I took the skid plate off, I noticed there was engine oil residue on the underside of the transmission. I then started looking around. As I was looking between the engine and firewall from underneath I noticed oil droplets on a couple rubber hoses. I couldn't tell where it was coming from. So I went up in the engine bay from the top and started looking around. I found a Sensor connected to the intake near the firewall directly above the oil on the hoses. The intake manifold had oil residue all over the hose. The sensor has a Purple and yellow and red stripe wire. When scanned with ODB II I noticed the EGR, BPS, EGS, DPF, HCC, AND NOx were flashing red. CAn I get any recommendations?
