I apologize if my translation is not accurate or good enough. Other Mandarin sifus can probably correct the parts which are in error.
----------
According to Peugeot. The cause of premature engine stop is normally caused by the following factors.
1. An error in the software occurring at idle speeds and accelerating
2. Communication between the accelerator to ECU and ECU to throttle body. There is data discrepancy and error in the feedback given from the throttle body to the ECU
3. Accelerating and cornering in an overly harsh manner. If there is a problem with the control module, just checking, cleaning
(for carbon built up), changing of spark plugs and solenoid valve alone will not solve the problem. There are obvious signs if the problem is caused by the spark plugs and this will not cause other various problems. The solenoid valve acts as an actuator, the chances of it having problems is rare. The problems caused by the solenoid valve are more obvious if it really developed a problem.
Peugeot has said that this problem (premature engine stop) still needs further analysis and study before it can be resolved.

Good attempt Zweimmk, just to correct some and add
The above statement is not made by peugeot but the investigation made by the reporter thru interview with a certain Vice President of the Beijing Institute of automotive technology .
This peson stated if the if the defect phenomena is a common problem, then the problem comes from the car it self, hence it belongs to a manufacturing defect.
The reporter has also interviewed the spokeperson from Dongfeng-Peugeot China, PIC of marketing (a certain Mr Ma) who stated these are isolated cases, and the reason can be many-due to the car, the driving, the fuel used, but he statetd he is not technical guy, so suggest feedback to aftersales and let them resolve it
In response to ECU software upgrade, an interview with another auto expert (Mr Lang), he stated that it is not the best solution for a new car that just have a few thousand km clocked, because many may be hardware issue. For an old car that has 300,000 km +, defect of ignition cessation has to do with carbon build up and Gumming. Normal 4 cylinder car, idle speed is 800 rpm approximately, if adjust it to 900 to 1000 rpm to solve the ignition cessation issue, not only it would cause other defect, it will also damage the gear, and not changing ECU but only revise sofware will cause the car to be in sub-optimal driving condition. ECU may trigger and operate under emergency/contigency programme, and may solve the problem in short term , but in long term, it will bring Three-way catalytic damage and below standard emmission and increased fuel consumption
However according to the rough survey, 2010 launched 408 models sold 50,000 units ++ (in China), 300 complaint at at 21-July 2010 is not a small number.
The source of the defect info is from China Car Quality Web, a subidiary of National Quality Inspection HQ or Division. The owner who reveal/reflect comes from Tibet, HongKong, Macau, Taiwan and other places nationwide, so the reporter questioned the claim from Dongfeng-Peugeot China, PIC of marketing (a certain Mr Ma) that it could be due to local auto fuel quality issue that may not meet the 408 fuel standard demand. More over, how can a car sold in China, not adjust to local fuel standard, and blame now on the fuel standard instead as the cause of problem, and to the reporter, that is really not being reponsible.
one owner complained one year the IC (Ignition cessation) problem happened more than 10 times, first time after one month having the car, after that continuosuly happening, especially at low spped, after software upgrade at the 4S centre, not resolve, after changing oil filter also cannot, after carbon deposit cleaning, and change to ron97 , from April 3rd to 17th June no more issue, but after 4,000km when cornering at car park, it happened again. The symptom before it happen is the power becomes tiring soft, lesser power when accelerate, longer response time from stepping on accelerator, and unstable idle speed, heavy steer.
Another owner bought in May 2010, first batch, after 4,000 km about 16 October 2010, it happened first time, intially he ignored it , then it becomes more frequent, from one time half monthly become weekly, 3 days once, at last 2-3 times a day. Changing engine oil, cleaning valves, still cannot solve, upgrade software then , it stoppped, then in 8-7-2011, it happened again. It recurred after 1 month, than 10 days after that, so it has definately come back.....
