P0400 after cleaning egr

[Swedge]

So I was getting the car ready for its mot and gave it a good service

Took off the egr which didn't look too bad but gave it a good clean with oven cleaner

Put it all back together and now I'm getting the EML light

Its plugged in correctly

Strip off and check inside?

I've tried clearing the code but it just comes back

piston inside sticking, take the top off and check if its moving freely

[Swedge]

It'll only move with the electrics won't it?

Does It move when the ignition is switched on?

[paula9568]

did you take the black top half off,fixed by 3 small screws

[Swedge]

Yep took it all apart, cleaned the inlet where they get goes on

Cleaned the boost sensors well put it all back together and I'm still getting it, the code won't clear at all

[paula9568]

make sure the piston moves freely under thumb pressure

[Swedge]

Yep moves very easily

Fixed it, I thought I'd spray come cleaner on the plugs in case they were corroded

1 of the pins in the egr was bent
