I noticed a small puddle of what i originally thought was Oil on the pavement where I had parked for an hour earlier. on further inspection I used my finger to move the Oil from the tray and the liquid was clear and smells like Diesel. Its located under the rear passed side seat. I filled it to the brim 2 days ago and have only just noticed, has anyone else had this problem and know what i need to fix or is it because i may have over filled the car?

Hose it down and then wipe it clean and then see if it continues dripping.

 

I had the same problem. The fuel filter on that side had a hairline crack. Suggest also to replace the fuel pump at the same time to save on labour if possible.

Good luck
