Hello my name is***** the fault code 2511-

2511 (001) Component Y27 (Exhaust gas recirculation positioner) does not function properly. Positioner signals fault X.

Basically you need to order exhaust gas recirculation valve with part nr. : A6461402460

BUT I always recommend you check with the dealer for the correct part number in case it was updated. Hope this information helps.

Hi I understand about needing a new egr valve for the fault but hiw do I tell when it has or is becoming active or even if it is causing the low power as no engine light comes on cheers

If you have that code then that is absolutely the reason for the issue. Some scanners can tell you the time and mileage the fault Happened at. The best way is to drive the car with a scan tool hooked up and watch the values when this happens.

Expert:  Lou P. master tech replied 1 year ago.

Egr valves become active at rpm's above 2,000
