Dear fellow W205 owners, Just to keep you guys noted about my recent experience, with a terrible fuel leak. It started about 2 weeks back, that i notice the presence of fuel (by smell) almost each morning. As i had to rush daily to send the family to school and work.. i only could check after the end of the first commute. Opening up the hood, there is no more fuel smell, used torch to shine onto the undertray and its dry... so i left as it is. just over the weekend, since i had more time in the morning, i started the car, popped the hood and decided to check.... i started to smell the same fuel smell again... so started to shine my torch at the undertray.... i could see a puddle (which i initially tot it was water residue).... Just a min into the engine warming up, i start to see dripping! i immediately headed down to the workshop and have them check the car. Again, because the car has fully warmed up, there was no more leak! trays were just slightly wet and nearly dried up. Workshop then noticed the fuel stains around the high pressure fuel pump, and told me to leave the car overnight so they can check the next morning when the engine is cold again. True enough, they found the source of the leak. the factory clamp on the fuel return hose was not tight enough. After inspecting the hose, they said the hose was good, just the factory clamp wasnt tight enough. So they added another clamp and this fixed the fuel leak. I will monitor for the next few days to see if its really resolved. If you encounter the same issue where you cold start your car, and you smell presence of fuel, please do check for leaks, it can be as simple as checking if your undertray is wet or damp. I have checked that the a/c water drain will not drip at that same spot where the fuel leak is. I attached some pics to show you the leak, and the source of the fuel leak. As there is no modifications made to the fuel delivery of the car, i consider this a production defect from the factory. My car is purchased from PI, and even the PI told me this is not considered as wear and tear, and they will warrant the change of parts if needed. Hope this helps any bros, as fuel leak is a very highly dangerous situation we will want to avoid! IMG_3590.MOV
just replaced a radiator S$800 (low sg stock) due to multiple small leakage damages, checked & noticed some leakages were damaged by small rocks/pebbles~ wonder if there is any way to prevent damage by hiding wire mesh behind front bonnet grills but not affecting air flow with this warm climate we have here~
