Hey all, I'm probably just going to end up at VW for this, but my 2014 TDI R-Line surges when shifting from 4-5th gear only. It happens the first time, but then is normal after that regardless of whether or not the car is up to temp or cold.

Examples:

Cold start in morning, first go through of the gears and the engine jumps a few hundred RPM before settling into 5th gear.

Hot start after sitting for a few minutes, engine will surge a few hundred RPM again from 4-5th gear.

However, once it's gone through all the gears once it won't do it again until the car has been turned off and restarted. Is this a programming issue or a mechanical issue? I don't have any lights or codes, and don't have a VCDS to check anything either.

If you're under 100k you should be in warranty...

I am. I'll take it to the dealer, it's just a pain in the arse, but I suppose less of a pain than trying to figure it out on my own.

I'm not sure what you intend to "figure out" when you don't have any diagnostic tools.......

My 2014 60k did similar until I cleaned out the inlet manifold of soot laden crud.

Probably not related, but how old is that transmission oil?

It's original. It has 88k on the clock. I was going to do a flush and filter change at 100k.

Let the dealer figure it out. Could be a bad torque converter

TC is involved in all gears\shifts.... even if it was the TC lockup, it should manifest itself on other shifts not just the 4-5.
I'd guess a sticky solenoid, but there's just too many in the 0C8 to guess without any diagnostic data. (VCDS would probably report a fault or you could at least monitor some MVBs to narrow it down a bit)
