Welcome, I'm Chris (aka Moose). Experts aren't employees / agents of Just Answer. We are independent service providers using the Site to sell their Expert knowledge to Customers. I strive to provide EXCELLENT 5 STAR service, let me know what's needed from me so your pleased.

Many diesel owners use performance programmers as well as alter or disable the EGR system. Has that been done on this vehicle?

Thanks, ***** ***** vacuum pump is over 19" vacuum at idle. Check EGR passages for carbon and clean out if needed. If those are fine and the monitor still will not complete then we need to do the diag steps based on the EGR storing a code like P0401.

Thanks for asking your question and letting me try to help you.

If your confused on why or how to rate me, let me know.

I'm only paid from the deposit you've made when you rate 3,4, or 5 stars.

Follow up/Reply as many times as needed before or after rating.
