It should be done every cam belt service and if you don't have the Volvo tool, try a big pipe wrench! To help free up the valve, use WD40, but then use brake cleaner (Or switch cleaner) to clean it. Use a new crush washer not a paper gasket and a new O ring for the intake. The bolts should be refitted using a low stregth Locktight to prevent corrosion. If you have to use a pipe wrench, it's a good idea to have a new EGR valve (Often made by Pierburg) on standby. Some folks have even broken one of the 3 flanges using the Volvo approved tool, which is probably why their dealers always replace rather than clean EGR's. Some mad engine modders clean their EGR's with the engine running !! The Mod involves drilling a hole and fitting a small bolt in the intake that allows a fine plastic hose to be inserted all the way to the EGR. Then you use a can of Liqui Moly or 3M diesel EGR cleaner (Listed in their Pro systems) that already has the hose fitted to spray in solvent whilst the engine is revved up. Not a job for thee faint hearted and it causes a lot of smoke. PS: Not had to clean my EGR for 150K km (I did get the intake done) cos a good blast on the Autobahn does that job. It also cleans up the turbo system.
