Done 1300 miles in C4 Picasso EGS. Have noticed that on cold mornings car fails to change from 2nd to 3rd and then 3rd to 4th whilst in "auto" mode, I have to use paddle to change up. Has happened a couple of times whilst warm too. Have tried feathering or booting the go pedal to no avail, end up doing 40 in 2nd......no change up.
Took it in to Citroen and technicians say no fault showing, but you can expect gears to stick until car warms up. I say fiddlesticks to that. Time will tell and see if it gets worse.
Any other EGS users find the same thing happening?

I don't know about EGS, but the same thing would happen on several automatics I have had when starting off from cold. Hopefully nothing to worry about.
BTW - SWMBO saw one this weekend and started musing about replacing her Trajet, for something a little smaller. How do you like the C4 Picasso?

In a conventional auto 'sticking' when cold is usually caused by a sticking governor. This is a common problem on older 4HP14/18 and is caused by 'varnish' and debris on the governor. USually as the fluid warms up they free off. An automated-manual gearbox does not have a governor because all of the control data (road speed, rpm etc) is electronically sensed and the shifting of the transmission is carried out by external actuators. It is totally different to a conventional automatic.
In the context of the EGS this behaviour sounds a more worring fault and I simply cannot believe that the transmission control software has been designed to hold low gears in this way. 40mph in 2nd is ridiculous. I would say that there is a transmission fault, although I don't know enough about these transmissions to say whether it would be electronic or mechanical. I am very much averse to CVT and automated-manual transmissions - they have a very chequered history so far. I think finding a technician who understands the system adequately to diagnose and repair it could prove difficult - you need to do some straight talking with the dealer and if their techs can't find a fault then get them to call in the regional engineer (or whatever Citroen call him).

Thanks for your input Aprilla, appreciated. Not being the slightest bit technically competent, I have given the benefit of doubt for now but I closely questioned the guy on the service desk using my old Hercule Poirot powers of deduction:
1. If it is a known element of EGS why didn't they say so when I booked the car in at 8am today? They told me the news at 5;50pm.
2. Why has it only started after 3 weeks of ownership and not before? i.e. it has been pretty cold on a number of days for the past three weeks too.
3. Why did it happen after 70 mile journey? surely it was nicely warmed up by then?
4. Why does it change ok from 1 to 2, then 4 to 5 to 6, but not 2 to 3 or 3 to 4?
Answer? "If it happens again, call and we will come out" I will hold them to that, but intermittent faults are hard to get to the bottom of aren't they.
