2.2 i-ctdi imrc control solenoid

Hi, guys,
Recently I have changed the maf and the car is now driving really good, but the only remaining problem I have is the imrc. It acts erratically sometimes and my car makes a bit of a black smoke. The suspected faults are present p2004 and p2017. The solenoid is notorious for its failure and I don't want to spend time and money on the same broken part. I have been thinking about putting another solenoid on this place /for example the same as the turbo boost control solenoid/. I can find it pretty cheap from a scrap yard. Then I can make the one hose longer and change the connector. I don't see any reason why won't this work. It is just a vacuum valve with two wires. When you apply voltage it opens and vice versa. What do you think? Hasn't anybody tried this?

It's worth a try, I believe the little diaphragm that regulates the vacuum pressure is actually the same on pre and post facelift cars. Let us know how you get on.

We definitely need to find a fix. Do you know why there is a white plastic cylinder on the egr and turbo vacuum lines and what are these for? I have never thought of...

Today I have obtained a vacuum solenoid pierburg 7.22341. I could not find a honda boost solenoid and I have decided to go for a random vacuum solenoid. The results are generally promising. With this valve the IMRC is actuating correctly, there are no faults and engine performance is great. The only problem is that sometimes it seems that there is not enough vacuum to the diaphragm and the rod is rattling. I am not sure if the problem is in the valve or the diaphragm. I will try to source the original turbo boost solenoid and experiment.
What's interesting is that the IMRC has different operation when engine is cold and hot. When cold there is no vacuum applied idling and when revving vacuum comes and the rod pulls the IMR. When hot /probably coolant temp dependable/ vacuum is applied and the rod pulls the IMR when idling, when revving the vacuum is cut and the rod is released. I have seen some videos on YouTube of this engine which confirms it, but I don't know which is hot and cold. Can anybody confirm this? The fault with the IMRC seems solvable so far.
