The check engine light is on, Swedish engineering says the code for faulty diagnostic pump came up. They checked and said that the diagnostic pump is bad. The estimate for repair is over 700$. I can not find anything about a diagnostic pump specifically. Any info out there?

 

What year is the car?

 

2004 xc70

 

I didn't think the 2004's had the diag pump. I thought it was newer cars that had them.
