I have a P1264 code coming up with loss of power, I have changed out the turbo full service cleaned the white filter with vaccine lines coming off it. Cleaned connections to injectors turbo. I have checked inside the inter cooler and down inside the intake on engine on the LH side for carbon build up. Checked the usual wire break area on the LH side of the sump and no worn wiring. This engine has 300,000kms new injectors 20,000kms ago. Do I bite the bullet and take to auto electrical.
