Laguna II EGR valve removal

Going to have a go at cleaning the EGR valve on my 04 reg 2.2 dci as it's started smoking well again and I've had a couple of orange "Fuel Injector Fault" warnings over the last week (which don't seem to affect the running and disappear when I've switched off and started up again). I know there are loads of threads about this but I've still got a question. It seems a few people have had a fair bit of trouble removing the EGR valve. Does it have to be pulled straight out or will it rotate in it's "barrel" - in other words if it won't budge can I tap it gently with a hammer against one of the lugs to rotate it and loosen it. Also is carb cleaner the best thing to use on it once it's out or should I try something like a good injector cleaner?
Thanks

The EGR valve usually gets well carboned up and I have found carb cleaner the easiest to soften it up - seems to work the fastest. As you say gentle taps with a light hammer and punch in a a rotational direction seems to work best. A few taps one direction and then the other and keep applying the carb cleaner. At first it doesn't seem to move but it may require some patience. When reassembling a smear of copper type grease will help removal in the future. Don't be afraid to lash plenty of the cleaner on but on no circumstances attempt to start the engine until you are sure it has all evaporated - it likes adding rocket fuel if it gets into the cylinder

Thanks Noel - always the first to respond and great info as normal. First time I've attempted this (supposedly) simple job so needed to make sure. Just need a decent day and the time to do it to coincide, not much chance this time of year with no garage to do it in!! What do you reckon, a couple of hours to do it, or more?
Thanks

I spent closer to 3 hours getting the EGR valve out - I just didn't want to do any damage and had numeropus cups of coffee whilst letting the carb cleaner do its work. Why work when some wee can of chemical can quietly get on with the job - that my motto.
Have you found the post and pics for the 1,9Dci engine on the forum.

Yes, seen that thanks. Spent many happy hours reading through anything I can find about this, including turning it round so it don't operate! Give that a miss I think. Some good info on here with plenty of pics, a real useful site. Had this car about 9 months and tho it's got full service history I'll make a bet that the egr has never been taken out before or certainly not for a long while and will be a right sod to get out - that's the way my luck goes! Even thought about buying a new one off ebay if I can find one so I can have a clean spare ready next time (and just in case I bugger my old one up while cleaning or it turns out to be faulty). Lot of dosh just before Christmas though.
