Their first reaction was of course to replace the EGR Valve and cooler at 1600 €, because the ones installed are still the original parts. The replacement parts are improved apparently, so they want this to be replaced first. If that does not the trick, they would look further. So I am afraid that no dealer will touch the car before the new EGR system is installed, so I bought the parts for repair by myself. Will reset the fault codes after that and go from there.
More reason to believe that the EGR valve is not sticking, is that you can move the actuater by hand without any hickup, when the cover is removed.
I checked MAF air flow sensor with my OBD2 unit, and seems to be working fine. Don't know what to check next.

Bummer. I replaced the EGR valve and cooler this week, and it did not solve the "reduced engine power" message. It came back after a few miles of driving. I replaced the air intake pressure sensor as well, since it was very dirty with soot. The EGR valve itself seemed to be ok and the cooler was pretty dirty, but not competely blocked
Anybody have an idea what to check next ?. fault code is P00BC.. thanks
