The car went into limpmode today (i though clearing out all the EGR stopped this) after about 20 miles continues driving in 6th gear around 75-80 mph, restarted the engine and was fine again then on the way home it happened again.

The car wouldn't go past 3500 rpm but still capable of doing some speed.

Scanned the car and came out with code above, turbo charger feels fine - no whistles or smoke which i think now comes to checking the diverter and the charger pressure control.

Am i going down the right track in thinking this, also where can i find them on the car.

I put some cleaner for the turbo in the car what the garage gave me and seems to be going into limp mode less, is it just the vanes are sticking? (though that only happened with over boost? not under)

I've seen the mr muscle trick down where the egr pipe connects, should i try this?
