few months ago i changed my fuel filter on my 1.6 tdci focus 09. (econetic), spilt a bit of fuel and then thought i had an odd smell in the cabin when using the air system.

 

kept an eye on that, and that seems all fine theres no sign of a leak and hoses are attached perfectly.

ive had this smell a while now and am running out of ideas.

 

today i changed the oil, and i had to remove the air inlet hose to the engine to access the fuel filter, this is attached to the turbo and the air filter housing, and i noticed when i removed it, there was liquid inside it. and it smelt of this smell that ive been getting inside the car when the air is on, you can also smell this odour standing in front of the engine when its running.

 

the odd thing, is this smell only comes into the cabin, when the air is from the outside. when i have the air to be recirculated, the smell doesnt came in. 

 

any ideas? ive just read that a possible sign of an EGR being stuck open is a "slight or strong smell of fuel"  

Do you have a/c? Maybe get it cleaned and re-gassed if you do.
Did you change the air filter and clean the housing and pipe work?
