Hi,

 

I have an issue of petrol smell in the cabin. Have been looking around the forum and some suggest it might go away with changing the filter, however I find it comes in from the vents (i.e. would be pulling in from the engine bay I assume). I have tried to look around to see the probable culprit but to no avail. So following another persons advice on this forum, to take it to a workshop sooner rather than later, but not sure where to find a good one. 

I have not used workshops in UK before, so if anyone could suggest one in Nottighamshire region would be perfect. Otherwise, if anyone has any ideas where to check myself for probable leak, then it would be much appreciated. The smell comes in usually after opening the throttle a bit more (i.e. not during idle). Especially notice after driving for a bit and then coming to stop. Again, if I turned vents off, it would not pull the smell in, so I suspect the leak to be somewhere in the engine bay.

Also might be unrelated but get the slightest 'cough' every now and then, like a singular vibration that can be felt but does not really show on revs and when looking under the bonnet, is very hard to observe it by looking at the engine. 

78k mileage, 11 plate, 1.2 TSI. 

Any help really appreciated!

I can't see that replacing the fuel filter or the cabin filter would/should change much, unless the fuel filter was corroded and so leaking slightly.

 

These smells should not exist so it sounds like you have a fuel leak under the bonnet somewhere, as yet undiscovered.

 

Why don't you just Google VAG Indie or VW repairs for your close area, there are bound to be a few around.

 

Slight petrol leaks on warm/hot areas are not going to hang about for you to witness, there is a high pressure fuel pump in there feeding a common fuel rail that the injectors plug into so look closely around there, but if you don't feel that you could sort it, get it seen to asap.

Hi, thank you for you're reply.

 

I kept looking around the fuel inlet and found a hose that is not connected. I found where it goes in, but as it has a broken connector, it is  very loosely connected. Tried to look through repair manual what the part exactly is called but couldn't find it, nor could I find any pipes that fit the criteria being sold on different online parts stores. 

 

Is there anyone who would know what this part is in the attached picture? The plastic part can be removed so perhaps could just buy the connector and not the whole hose. 

Found the part and already now fixed! No more petrol smell feels good.

I've not got a car with that engine, but that does seem to be a "popular" failure with these engines now that you have mentioned it. I hope they sorted/changed it for the newer versions of the 1.2TSI engines.

Sorry for not clearing that up, that is the PCV valve, it controls the volume of air being drawn through/out of the engine casing.
