oks was having a clean under the bonnet and noticed that the EGR Vale had a lot of oil round it,

Going to clean it soon just want to know would it be best to clean inside the black pipe going down the (i think it goes) the intercooler also would it be best to clean out the intercooler at the same time? Also would you recommend replacing any part i.e gasket, seals if so do you know part numbers and prices, if so is there a guide to removing and cleaning the Intercooler?
Also me being heavily handed again i snapped the piece off the dipstick pipe

think i had already been glued at some point


is that the part number 038 103 663 ?
