VW TDI ALH Injection Pump Quantity Adjuster Bad?

Описание

From what research I have done and found on the internet, the quantity adjuster in my injection pump is bad. I'm thinking due to trash/metal particles under what is seen in the video. To my understanding, when the ignition switch is switched on, the QA needle should do a full sweep and return, this one sticks and then eventually returns. This is what I believe is causing a hard code of "17970 - Quantity Adjuster (N146)
P1562 - 35-10 - Upper Limit Reached - Intermittent" This causes the car to surge at idle. If I am wrong or correct, post and let me know! :-)
