The DF301 code refers to an air intake fault.

Check the inlet ystem for leaks and also the turbo pressure sensor and its solenid controls - could also be a leak in the vacuum pipework.

Check the inlet plumbing for signs of excessive oil.

Has the EGR valve been checked.:)

Hi,

I am having exactly the same problem same year and model megane.

Did you fix this?

I put my foot down and reaching 65 plus i have a sudden loss of power, check injection appears and a spanner light.
I had a machine plugged in and it came up "DF301 air intake circuit malfunction"
Turning off the engine and back on clears it. Even on the plug in machine. If i go 65 plus again it comes back on.

Any ideas?
please let me know or anyone else?

Good to know. I also can share my experience in filling forms. BTW, there is an online service through which you can fill out a IRS 1099-MISC, the fillable blank is here *******
Removed dodgy link out of above quote - The Chuff

Can you explain what this is please
