Need some advice. I have an E350 year 2012. The car is a V6. I have fumes smell come into the cabin. I have been to see several mechanics and everyone of them has told be something different.
Some things i have been told...
1.there is a small oil pump below the turbo that is prone to leaking.
2.The DPF is clogged. But i do not have an engine light on
3.the exhaust system has a hole/leak and this can allow fumes to find their way into the cabin
4.Cabin filter....which i have had changed
5. Engine Oil cooler....
I dont really know which way to go and would like some guidance.

its normal for the engine to leak yellow coolant and smoky oil BUT the smoke shouldn't get into cabin - That is abnormal!
Make sure the engine bay battery cover is installed properly else it wont seal. Cabin air depends on that cover being sealed well.
Open the engine hood and look near firewall on passenger side... that big black box with snaps.

What is your engine model?
1. You car has no turbo.
2. DPF is for diesel cars.
3. Are you smelling raw gasoline or exhaust fumes?
4. Cabin filters are for outside air, not engine compartment air.
5. Engine oil cooler? Leak?
You need to find other mechanics. They all sound like idiots, especially the first two.

1. its a 3ltr V6 Diesel
2. I know. Mine is a diesel
3. exhaust fumes. i have noticed it only becomes apparent after a few miles of driving. Also, i had the car at the mechanics and he said your power steering fluid res was empty. He was confused as to where the fluid had disappeared to.
4. Understood
5. perhaps. I have had it looked at but nothing concrete.
