advice for cleaning EGR

[Calamity_Kai]

Hi all, just bought a 2005 Ford Focus 2.0L Ghia TDCI. i have had it for just over a week and started having some issues, so took it to a garage and had a print out of the fault codes. I was told by the mechanic that the egr has had some sort of water in/ on it (i think from the full engine valet the guy before me had done). he also showed me the egr plug, which, as previously mentioned, had water all around the seal. he advised to remove the valve, give it a good clean with brake cleaner, and properly dry it out. I do a fair bits on my vehicles myself, but just wondered if there were any tips/ tricks to make the removal and refit process less stressful and any tricks on cleaning it as best as possible!

 

Many thanks!
