DO NOT take off the bottom cover. Dr A has warned against doing that.
The TOP cover can be carefully removed and the interior cleaned. That whole mechanism is the part that extends/retracts a rod that has a seal on the end in the EGR bell, which regulates how much boost pressure/exhaust gets through. The part that is important to clean is the rod and the interior of the bell that goes to the exhaust, which requires removal of the EGR to get to. NO parts are removed from the EGR itself.
