Recently I had engine light on a few times a week depending how much I drove. The code could be P0171 or B2aaa or B2aaa Pd. I had replaced Crankcase vent valve and its short breathe hose, cleaned Mass Air Flow sensor. But I still got the engine light on and the code. Upon reviewing photos I took I found one hose is cracked. I do not know what hose is it and if this is related to the engine light and the code. It's 2008 Passat 2.0T FSI. I took a few more photos that show it's location and the entire hose and its two ends. I circled the hose with red lines. Please help me identify it so I can buy a replacement. Thanks.
