Car Forum / BMW Cars / January 2008E46 Petrol fumes in the car!!!!
Hi all, There seems to be petrol fumes within the car - which seem to get stronger when stopped in Traffic - has anybody else had this problem??? Or know what it may be?? Mine is a 2002 e46 316 Thanks, Keith >There seems to be petrol fumes within the car - which seem to get >stronger when stopped in Traffic - has anybody else had this >problem???

Gas fumes either can come from under the hood via the cabin air intake, or from the trunk via a broken fuel tank venting system. The thing about gas is that it is very volatile and very smelly, so one drop of gas can stink up a whole warehouse. The high pressure fuel system does not take too much to leak. On the other hand, if you are in the habit of topping-off your tank, you can also fill your charcoal canister up with fuel very easily and make one hell of a stink. --scott  Signature"C'est un Nagra. C'est suisse, et tres, tres precis." Hi Scott, Popped both the hood and the trunk Seems like it is coming from under the hood alright Tank was near on empty when it seems to happen. Any idea what it could be??? Should I just leave be and see if the smell goes??? Thanks, Keith. > >There seems to be petrol fumes within the car - which seem to get > >stronger when stopped in Traffic - has anybody else had this [quoted text clipped - 16 lines] > -- > "C'est un Nagra.

This is bad, and it can be a pain to find because it might not be leaking enough to leave an actual stain. Look at the fuel hoses, the outer ring of the regulator, and the fuel rail. >Tank was near on empty when it seems to happen. I don't think this is relevant. >Any idea what it could be??? Should I just leave be and see if the >smell goes??? No, you need to get it checked out immediately before it gets worse. The wands used for exhaust emissions testing make this a lot easier... the mechanic can start the engine, wave the wand around and when he gets it near the leak it will go right off the scale. Without it, it's a matter of sniffing and feeling and seeing where the tiny leak is. A tiny leak will become a big one in a lot of cases, and big fuel leaks are bad. --scott Signature"C'est un Nagra.

Thanks for that Scott - will bring to mechanic in the morning Seems to be quite a string smell too If I knew what I was doing I would have a go myself Hopefully not an expensive job > >Popped both the hood and the trunk > >Seems like it is coming from under the hood alright [quoted text clipped - 22 lines] > -- > "C'est un Nagra.

Use a match. 8) Just kidding! Found the source of the problem There was a leak where the fuel line goes into the engine (near the injectors) The pipe was off a little causing a leak Scott/anyone - are you familiar with this piece? Excuse my complete ignorance on this - I don't even know the name of it! :) Put the pipe back on - but there is a black piece of plastic in the pipe - is this supposed to "click" back in? Or is there some kind of fastener missing? There didn't seem to be anything broken off it. > >>Popped both the hood and the trunk > >>Seems like it is coming from under the hood alright [quoted text clipped - 6 lines] > > Just kidding! |
