Friends, the engine light came on in my Peugeot 206+, I had it checked. It says P1457, vacuum cannot be drawn from the tank and even gives the code. I would appreciate it if you could help. What is the cause? I showed it to a few mechanics, all of them said different things. Some said it was a turbo, some said it was a diesel filter. Some said the fuel tank might be clogged. I am confused about what to do. Has anyone encountered such a problem? Thanks in advance.
