Hi Guy's,
I had this code before in the summer and them I cleaned the whole piping system from dust but did not take a part the Canister it self to check the Valve. Reset the code with the ODBII diagnostic system and was OK till now.
Came back again.
It is possible to disasamble the canister to check the vale and/or clean it?
What will happen if I leave the code for a few day's?
Will this affect or damage the engine?

Thank you in advance
