Default a few new error codes

Hi

I have a v40 D4 (2015). A few weeks ago the egr seized open.

I managed to remove it and give both the valve and cooler a clean. It now seems to work fine.

That is except that i now have some new DCT. Specifically i have 2, one that doesnt trigger the engine management light and one that does.

The two i have are:
P1569 - "Intake Manifold Runner Control Circuit Low".
P245A - "Exhaust Gas Recirculation Cooler bypass Control Circuit (bank 1)"

Does anyone have any ideas for what to check in order to fix the issues?

I would use smok machine to check potencial crack in the manifold, they do crack and are hard to diagnose without smoke

Thanks

I reseated the intake sensor power and that seems to have gone now.

But even replacing the bypsss valve still gives me error P245A

Then it looks like the EGR valve is faulty, any symptoms or just check light?

Hi,

So I have the engine light. Sometimes it will hesitate and every so often some revs will drop while idle for a fraction of a second
