Yeah i had the P2008 come up on mine too..
100kmh cruise control overtaking a truck on a highway and engine light on, no power, roll to the side.. not a nice thing to happen.. symptoms for me were not kicking down when going up hills, turbo was overboosting (i saw it hit 18.9PSI) the most i have EVER got previously was 15.9PSI.
P2008 on my smart meter, i had it happen to me 6 times in 4 days, so after looking it up i pulled off the intercooler and found a split in a vacuum line connected from that little grey solenoid that Boxhead posted a pic of and the other end to the EGR manifold.. i thought 'pisser, found it' and fixed that problem.. but no difference.
So i took it into workshop and they found a dead short in the vacuum control switch which caused the butterflys to not open and close in the egr and was throwing the codes.. there was quite a few of them in stock at toyota, so i assume they have had to replace them before.
replaced it,cleared the codes and im off again. Here's a pic of vacuum control Switch that dead shorted if anyone's interested.
