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?

That sounds like the torque converter is dropping out of lockup and back in again rather than anything else. You could try scanning the auto transmission rather than the engine to see if anything is recorded there.
The torque converter issue was a fairly common issue on the D2, but the next step after that was usually transmission failure. Do a search for A8 transmission thump.

Don't say that!!
I can't have this box going. That's why I broke the A4 cause the box failed. I'll do a full scan and see what comes up. I've not seen any codes for the auto box coming up. Worse case, if it is the TC, I assume a new TC is needed and a box service won't help?

When I got the car it has less than quarter of a tank in it. I then filled up with Sainsbury's and I can't remember or noticed it doing it then. Then put Texaco fuel in on friday.

could be as simple as that then.
Mine runs like a bag of spanners if I put Shell Nitro in it, but loves Tesco Momentum
