Really has the be the EGR valve on mine, does anyone have an idea how to clean it up on the car??
Yes you can, might depend on how bad it is though.
1, Remove rubber elbow section pipe on egr. Inspect with mirror/torch - you can see the valve and how bad it is. If it's chokka block then maybe best to remove, but mine wasn't.
2, Remove bottom metal 'concertina' pipe (2 small studs 10mm I think).
3, You can then move pipe to one side.
4, Using a 1/4 drive 'T' bar and extension with a 10mm socket on (or similar - it's just a matter of finding something that fits and you can move easily) you can push this up from under the valve where the concertina pipe was and physically move the valve up and down to free it off. Use EGR spray and a tooth brush, and then keep working it up and down.
Again, it's up to you to determine how badly coked up it is but I wouldn't remove manifold unless absolutely necessary.
