No Throttle Response

[Pazz]

Only when cold & after a couple of mins driving - no throttle response after coming to a stop/slowing to a stop. Leaves me stranded at junctions!
Shut engine off - restart - won't rev, even in neutral. Sits on 1k revs.
[FONT=&quot]Place in neutral and it won’t rev whatsoever, place in Drive or Reverse and put foot down, after several attempts it’ll kick in, and then drive as normal for the rest of the day! - Always OK when warm.

[/FONT] Indications
None! No transmission flashing lights, no CEL or DTC's, nowt in memory when scanned with VCDS

Tried
Throttle Body & Butterfly plate removed & cleared of gunk then re-aligned adaptation via VCDS
Garage checked for vacuum, lean codes and emissions ok
MAF & Air Filter replaced
Brake Pedal sensor replaced – it cut’s out throttle and is “known fault”
10 tanks of Premium fuel used, and countless injector cleaners/additives over past months.

This has been occurring for about once a week for 6 months now.
Any advise gratefully received!!

the peddle is a fly by wire job, the server in the peddle may be screwed, in other words, no signal from the peddle, iv seen this a few times, how many times to d you think your peddle has been pressed etc etc?

In Swindon unfortunately - on so many levels.
It's done 70,000 miles, but never had an error code thrown up for the accelerator position, and it's always OK after the first mile or so, and I do 90+ miles every day.
Was thinking it could be the transmission, but would still expect the engine to rev up in Park or Neutral.

Still worth a punt tho! Have you the part No? I'll see if I can get one locally.
Ta.
