Strange Throttle Issue

[CabC2]

I have a tip, but I drive it manual (switching on the steering wheel).The car did this several times today over a long drive of about 280 miles:

Several times the revs wen up without me doing anything and having a steady foot. The same revs as I was accelerating from 60 to 65 mph, for example.

I thought it might be the transmission changing gears... but I was going in manual and it was not a gear change, just the throttle. Once they went up, the stayed. I had no luck replicating the issue. Although I think it was happening when I was between 3 and 4k rpm.

Any ideas?

Best check the fluid level and put either a PST2 or PIWIS on the car and read the faults.

Loren,

What fluid level? How can whatever fluid level affect the throttle? ?? I am taking it in, but I'd like to learn what you mean.

Thanks,

[Loren]

If the revs are going up without you moving the throttle then it is likely the transmission is slipping.

Slipping can be caused by low fluid level or a problem with the transmission.

Yep. That's what I don't want to hear, any problems with the tiptronic transmission not that I rebuilt the engine. Curiously, the trannie was fine until they changed the fluid at the 90k service a month ago.

I have heard that you cannot service Tips. Hopefully either that is not true, or there is nothing wrong.
