My rear hatch doesn't close completely. Latch on bottom and latch on door works perfect. When it closes, the system think it's closed. no light on. The issue are it looks ugly and come out cold or warm air from it when a/c or heater are used. Is there some way I can adjust? I tried to unscrew bolts and adjust both latche positions but no space to move around either bottom or door latch. Is there some way I can adjust?

I changed ldp twice (even they are in good resistance values) I checked valve on canister if it works at 12v. Changes purge valve. Checked purge valve (opens at 12v close at none) Changed change over valve and checked with 12v. Checked vacuum lines from both DVs to change over valve. Changed cap.(I didn't think it's cap but I changes anyway) Checked if there are any short/open circuits from ecu and valves on canister and ldp. I found problem at mutiple vacuum lines from DV to leak detection pump. After I replace and rearrange. Issue solved. No cell or no code stored in ECU for 2 weeks now.

2004 Cayenne 4.5 Turbo With generic OBD reader: p2403 with durametric: p2451 P2451: Evaporative Emission System Leak Detection Pump Sense Circuit - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light So far, I replaced oil separator diaphragm I replaced fuel cap I replaced purge valve twice I replaced leak detection pump. I replaced canister + another leak detection pump. I replaced whole canister assembly. So, I replaced LDP 3 times so far. No problem with filling gas. Is there somewhere else I need to look??
