Default 3.0TDi hunting at low speeds

Hi guys

One day I'll put a post on this forum without asking for help!

The car is a 3.0TDI on a 05 plate with 48k miles on. Driving on the motorway it's fine, hard acceleration appears to be fine, but just cruising along at 30 the box feels like it's hunting between 3rd and 4th. Does this sound like an issue with the box or just a characteristic of the box? It's quite annoying that it won't just cruise along without the engine note constantly going up and down!

Cheers

Mine is a 06 plate with 170k.
Does exactly the same thing.

I've had the box serviced and full service history for the engine.

No idea what it is.
I'm siding with the box.

Sounds good. Going to try mapping it, see if the extra poke low down will stop it hunting if other peoples boxes are the same. Will let you know!

Unfortunately it's not normal, guessing nothing is showing up on VCDS?

I would of suggested a service but if Scott hasn't had much luck them maybe it's a sensor in the box that's playing up, is it getting the correct speed signal? Maybe try logging some data from the box see if anything unusual crops up.

No errors for me.

Not sure what to log from the box but a good idea.
