Default Surging. I think.

Car: 3.0TDI D3 on a 06 plate

Its only been doing it the last couple of days and not all the time.

Travelling along the road and x speed, no issues, not a problem.
Come to a hill or anything that’s enough for you to take your foot off the throttle coast.
The revs normally drop to between 1000 rpm or 2000 rpm and the needle will jump about 1-200 rpm up and then back down, then up and then down again.
Its just like you’re tapping the throttle with your foot causing the car to surge forward and each blip.

Its more noticeable in 3rd, 4th and 5th and mainly when its cold or warming up.
It will do it a little bit when up to temp but no where near as bad.

The first scan I did of the car reported these two faults.
005658 - Glowplug for Cylinder 1 (Q10)
P161A - 001 - Open Circuit

001025 - EGR System
P0401 - 002 - Insufficient Flow

But they never came back after the 2nd scan.

I will scan the car when the weather holds up now that I’ve been driving it for a few more days.

Anyone got any ideas on what to check or change?
