2 error codes: P0299 turbo charger underboost P0401 Exhaust gas recirculation flow - insufficient detected

Hi. I've owned a number of mk1 Sharans, which I loved but I've just bought a 2009 Alhambra Ecomotive because my last Sharan finally died. However I've got a problem which is fairly similar to something that happened on my Sharan Sport some years ago. The car has the engine management light on and when started says "Emissions Workshop". I drive it and after a while the flashing glow plug light comes on and it enters limp home mode. There is a slight smell of exhaust gases in the car when the heater is on and at night I can see some smoke (presume exhaust) coming from the front grill. The car accelerates before it goes into limp mode but it is noisy - like a fast ratchet sound, plus I can hear the turbo kicking in (there is some lag) and then I keep hearing a woosh as it dumps pressure. It does this as it's accelerating but not being driven hard - almost like pressure is building up but too much. It's not at the end of acceleration, it's continually through it. Took it to a local garage who have me the sucked in air and "probably hoses or the egr, but I don't like the fact there's some oil around the hoses. Gonna be costly". I've got a diagnostic tool arriving today so probably can get some codes but my question is, what is the likely issue and is it going to be costly if I get second hand or pattern parts? Thanks. Have to say, the dashboard is not a patch on the Sharan because everything is red light and is difficult to read easily whereas the Sharan was blue and red - much easier!
