Engine management light

So the dreaded EML came on. 2 weeks outside of the three year warranty period.

Looks like adblue related. Any advice or tips please. Error codes were cleared but light back on again.

Is the van driving OK, or is it in limp mode?

Have you checked the wiring, especially to the ECU?
Do you get a message on the dash to say that your Adblue needs filling?
Any other fault codes other than the ones above?

Van drives ok.
No limp mode.
No other codes than those shown
No other error messages in the display

It sounds like a wiring, low voltage, earthing type issue.
What is the battery condition like?
What diagnostic tool are you using? - may need to get a a more detailed scan using VCDS or similar.

I think it is a snap on diagnostic tool.

Battery always seems good. 72 plate van

The two bottom faults are logged because of a faulty coolant bypass valve, located on the passenger side - near the gearbox.

It will require a replacement bypass valve.

Sounds ok, is it easy to do?

So if we suspect an earth problem - any places to take a look for starters?

So got it VCDS checked at my convertor on Friday as had to go in for another item to be sorted.

Turns out it is my driver speaker isn't working and has become disconnected and caused the little yellow light.
So will need to take door card off and sort that out.

Bung some of the wynns adblu additive in

You don’t get an EML because you have a speaker disconnected.
