hi, i have a similar issue to the '2009 Insignia 2lCDTI - loss off power on acceleration' topic. The egr cooler housing was leaking so iv replaced that today, everthing was fine before hand but now im getting loss of power as if the turbo is not kicking in properly, its fine when cold but once up to temp the loss of power occurs. am not getting any fault codes but am getting an audiable warning once temp is reached and no message on the display console
Hi i managed to fix the proplem on my own.
Please close the question
