Can anyone point me in the right direction please? 2016 t6 dsg euro 6 engine. 70k miles and it's started intermittently revving to 2500 when I put the drive into park. Put it back into drive or reverse and the revs drop to normal. Seems to drive normally but I can feel when I come to a standstill if it's playing up as it is revving slightly higher than normal at tickover in drive.
Any help welcome
Thanks

Can you get a video clip of it?

Then post a link to the video on here from your online photo video album question mark or drop it on YouTube and post the link here.

Scanned for codes?

Any other issues?

Starts and drives fine?

We're on a campsite in the peak district - I've just started it up again and it went up to 2500 revs - stuck my hand up where the throttle linkage disappears to the sender unit and wiggled the wires and revs changed - eventually dropped to 900, wiggled again and up to 2500 - I think I've found the problem

Somebody else had the same / similar problem recently, not sure they resolved it.
Throttle linkage by Boeing by the sounds of it!

Throttle peddle assembly?

Or corroded connection?

These vans are fly-by-wire.

So the linkage is just a sensor on the peddel.

But for safety they have two sensors, each opposite way around so the van can determine if there is a fault....

Both sensors should read the same, but opposite values.... So assuming you have conflicting TPS (throttle position sensor) readings the revs will be wrong.

Can you post some pics of the peddle box area and the TPS connection?

Have you had a valet cleaning service done? A friend of mine had her cars electrics ruined with a ‘very thorough’ internal clean, it looked like the cleaning agent contained salts.

@Dellmassive - you may not remember but this van was one I converted from a full wav vehicle nearly four years ago with a lot of support from you guys. The throttle had been adapted to hand control which when I removed, necessitated cutting and re soldering the six wires to the throttle sensor in the foot well - I'm hoping it's one of those. I'll check and advise

Took out the lower dash trim today to check throttle wiring. Cut back the heat shrink where id re joined the wires and my joints, although not pretty were intact. Had to de solder them to fit new heat shrink and all back together and working ok. After my jiggling the cable and plug on Wednesday in the peaks it's behaved itself - I'm hoping the plug wasn't fully clicked home - fingers crossed
