Among others described more explicitly, I've logged the following codes, according to the newer scan tool (Autel MaxiDiag):
250016
25001B
250020
All say to see the manufacturer for more info!
Car is stumbling and throwing a regular code "Richness regulation fault" that it describes as intermittent. It also logged in capitals, RICHNESS ADAPTATION (ADDITIVE) - any help on this? I'm thinking the O2 sensor is one culprit, at 155000km.
A semi-related aspect: The auto trans throttle position sensor readout I get from the scanner (not the regular TPS readout) goes from 9% (restive pedal) to 88% (pedal fully depressed, HARD). Anyone else have a similar reading on their auto trans throttle pot?
Thanks, Adam.
Edited to correct spelling of title!

Those fault code numbers aren't listed in the Citroën diagnosis manual but what the manual does state is that the ECU must be re-initialised after any of the following;
disconnection of the battery,
disconnection of the ECU or the supply relays,
replacement of the idle regulation stepper motor or throttle potentiometer.
Failure to re-initialise the ECU causes the following running problems, engine snatching,
engine stalling on returning to idle
engine stalls on starting
To re-initialise the ECU switch off the ignition, then switch it on.
wait 3 seconds before starting the engine.
Also auto-adaptation of the richness.
engine hot +60°C
road test the vehicle for a minimum of 15 minutes, making use of the various engine speeds, in particular,
from 2500 to3500 rpm.
idling speed
full throttle (for 2 seconds)
The above is worth a try before delving deeper or spending money, Citroën must state it for a reason.
BTW "Heatstroke" are you having a laugh? It was -7°C outside my place this morning

Should have said - I do the ECU thing (key on, wait, then start) as a matter of course every few days.
Having trouble holding a signal from the engine ECU to my scanner - it seems to either not connect fully, or soon drop out. Wanted to get some live data screenshots.
Another Lexia vs "MaxiDAS" quessie: When I put the AL4 into gear (other than N or P) the reading for AT input speed nulls, but RPM are still displayed. Do you see that same quirk?
Regards, Adam.
