Just bought myself a Carburetor Cleaner and went into action.
I didn't need to remove all pneumatic system as described, only inlet hose above EGR and of course EGR itself. It wasn't that dirty and didn't stuck. But upper part of inlet manifold, where hose is attached to... well, I had something to see there! Hole was like 1/4 to 1/3 packed up with dirt. I covered bottom holes on EGR valve place to prevent dirt going too deep. With long screwdriver and vacuum cleaner I removed most of dirt, and remains with Carb Cleaner and cloth, wrapped around screwdriver. Estimated quantity of dirt was around 1/2 deciliter at least. This was the first cleaning ever, on D192T3 engine, 2003, with 144000 km. One thing I would like to point out: -My EGR valve does not come in two pieces. On mounting holes is obviously riveted together with thin cylinders or some sort. I didn't try to take it apart as it doesn't show any signs of hard moving. VADIS is not very useful here. It shows only one model of EGR valve for all models and years, and even there is pictured as mounted transversally on engine, rather then longitudinal as it really is. |

I had to remove all those parts so I can get to the turbo itself. Clean until you can see shiny metal parts under all that black stuff.. You should notice slight performance gain |

Friday night quiz....
lost power again, I was able to get home using more than 3000 rpms. At home I opened up the bonnet, removed that plastic cover and I noticed soot and some oil spilled on the heat shield, soot was mostly between engine and wind screen..... will take some pictures as I am working to find a fault.

Thanks for the guide, did the job yesterday and all now nice and clean!!
One problem I found was that the inner and outer bits of the EGR valve where actually joined together at the bolt hole. They had a small washer type thing (its probably got a proper name!) which joined them together but would spin freely when twisted with a screwdriver. This just made it a bit more awkward to remove as you had to work on the inner piece first. Before I had removed the valve the 'washer' things decided they'd had enough and I managed to remove the outer piece. Phil |

Aha, so your EGR is the same type as my - both parts are riveted together on holes?
When you took them apart, was there any dirt inside? |

Haha, I didn't see your post there! I spent quite a while trying to work out why they wouldn't come apart....
Anyway, there was quite a lot of crud around the sping mechanism that controls the valve. I'd recomend doing it at the same time, the rivets won't take much effort to remove once you have the whole thing out! Phil |

I'm thinking of doing this job myself. Do you guys replace any gaskets when you put it all back together or do you re-use the old ones?
