How are you getting on with your EGR warning light any luck in getting it sorted?
After having VW replace my EGR and cooler in Dec 2022 it has run fine for nearly 7000 miles and 18 months but now the Orange engine warning light has come on. My simple diagnostics OBD11 shows fault P040100 and states Exhaust Gas recirculation - Flow insufficient. Is this likely to be the new EGR at fault so covered under the 2 year parts warranty?
Why might the gas recirculation flow be insufficient? ie What could be causing it?
My van is a 2016 T28 H-LN 1968cc TDI BMT 103bhp with a mileage of 47,700miles
I Have changed to using shell Vpower diesel and BP Premium for about 4 refills to help keep things clean in hope that it will help.
Does this warning light just go off if the problem clears?
If I clear the fault can I expect it to come straight back on or might it take a while for the insufficient flow to be detected again?
If anyone can shed any light on this that would be great as this is also driving me nuts!!!!
Thanks
