Engine warning light - P0401

[james_bt6]

Drove the van into town earlier and on the way back the engine warning light came up on the dash in orange.

Once home, I plugged the Carista in and got the following fault code:

P0401 - Exhaust Gas Recirculation "A" Flow Insufficient Detected



Freeze frame :



Calculated load: 51 %



Coolant temperature: 90 °C



Intake manifold pressure: 160 kPa



Engine rpm: 2400 RPM



Vehicle speed: 101 km/h



Intake air temperature: 18 °C



Air mass value: 47.65 g/s



Absolute throttle position: 83 %



Time since engine start: 568 sec.



Fuel rail pressure: 114200 kPa



Ambient air pressure: 101 kPa



Battery voltage as seen by the engine ECU: 13.17 V



Relative throttle position: 69 %



Outside temperature: 18 °C



Absolute throttle position D: 44 %



Absolute throttle position E: 44 %



Commanded throttle actuator position: 100 %

I then reset the faults so the light went off on the dash, took the van out again and gave it a good blast up and down the A1 (75mph most of the time) van drove lovely, and no different than usual.

Is it something to be worried about/something I need to get seen to or can I just keep driving it normally in the hope it was a glitch and won’t show up again?

most likely the EGR clogged.

will need flushing or replacing.

a common thing on a T6.

what the age and millage?

 

[james_bt6]

late 2018 and roughly 57000 (I think) - is it an expensive job or is it worth just having it coded out?

Or would some RedEx help?

It's about a £600 part.

Around 1k Fitted.

That will give you another 60k / years.

And normal for a T6 of this age, just standard maintenance.

Personaly I'm not a fan of deleting etc..... I just do the maintenance.

Had mine done on both vans, about the same miles and years.

So much money!!!

So much money!!!

part of the cost of running these vans.

just maintenance, all modern diesels have similar setups.

.

a common job, have a look at local vw indys, you get it done much cheaper.
