Strong fuel smell in mk3 Ibiza cupra

[adam1]

Ever since i brought the car every now and then i get a stong smell of fuel when im driving, any ideas what could be the problem?

Possible causes (at a guess) - Coolant Sensor, iffy lambda, failing coilpack, dying MAF. Find someone with access to VAGcom to read fault codes is your best bet, or call in to the dealers, who will no doubt charge.

or a fuel leak/split pipe

I have recently had the same and found the problem to be where the plastic fuel lines come up into the engine bay near the air filter and they are connected to the rubber hoses that lead to the fuel rail....the rubber hoses had slightly cracked and the clips had losened so that a small seep was apparent...worth a quick check

maybe the top off the black carbon cannister up by the strut tower has popped off too... Fuel tank vent there.

Check correct fitment of FPR on injection rail if recently had any engine re-map mod's. The seals on this unit can become perished and/or worn during prolonged contact with fuel. Worth a look.

sorry i didnt say the outcome of my problem....


it was as 'ibizacupra' said, the feul tank breather had popped off, well had snapped off and the person who owned my car before me had cowboyed it.

I slipped some blue silicone hose over it and it makes a good seal and doesnt smell and more!!

cheers guys
