Please I need help, over a year ago I got a used Mercedes vboot 200 . But my worry is that at intervals I use to smell fuel odor inside the car while driving especially at hold ups and low gears like 1,2 & 3. I have consulted some mechanics but none has been able to dictate where the odour comes from.
Please any one with a clue? Thanks

1 thing is involved, you are patronizing quacks.

check the lid of the fuel pump casing and make sure its properly closed. For japanese cars, that will be the most likely cause. Am not a mercedes pro.

Yes I have replaced the tank cover and it reduced but still oozing after some days.

did you check if it was tightened properly. There is a rubber lining that comes with the lid

Of course the rubber lining is in tact. The very cover (I supposed ) that came with the car it lining rubber was cut so I have to replace it. And it was after I replaced it that odour oozing became an interval thing

I think your car may likely be running rich or having a failing injector pump, the smell can be as a result of excess fuel being injected into the system. My friend had a similar experience recently.
Did you replace your fuel pump recently?
Is you car idling rough?

I may be wrong, you can wait for more comments or visit a competent technician

check the O-rings of your injector nozzles. They may be worn out.

Thanks. But how did your friend solve the problem? Am interested please educate me .

Yes talking about failed injector, seriously this injector behaves differently from the Mercedes regular I used before. What I mean is that in that Mercedes regular I used before, when start the engine, it will take about 2-3 minutes before you can raise it.

But with this Mercedes vboot it's not like that. Once you started, it's ready to go without steaming for some minutes. Could that be an indication that injector has failed?

Once u can perceive fuel odour in the car ,this means their is leakage in your fuel line or evap system
Get a competent mechanic to check this through all this line.

Couple of years ago, I could also smell fuel penetration inside my car(Daimler 1989).
The fuel compartment is placed inside the boot, behind the rear passengers seat. Taking off all the panels and coverings revealed a leak from the tank itself.
Couple of hours later, fuel tank removed, leak sealed and all the fuel tank was covered in some sort of coat to protect it for a couple more years.
QED!!!!

In his case it happened that his was unburned fuel, the Injector was calibrated.
You can also check for leaks as suggested by others if the smell is strong and consistent.
