Multiple fault codes after difficult engine start

2011 C3 110bhp HDi, 124000 miles.

My daughter told me the other day that there was an 'engine requires repair' fault on the car with the EML on. Previously we had had this problem, and it was fixed by Citroen under extended warranty. They replaced one injector, but suggested that I should have all 4 replaced. However the warranty would only pay for for one and the bill for the remaining 3 would have been nearly £1000.

So this time it happened I thought it was an injector again. As there is no warranty, I wouldn't be taking it to Citroen, but took it to an independent with a good reputation.

Starting the car was difficult as the battery was nearly flat, and for a few seconds it didn't sound right. The car seemed to drive perfectly.

They read the fault codes and found the following.

P0269-Permanent Fault-Injector 3 flow correction value too high or low.

P0266-Permanent Fault-Injector 2 flow correction value too high or low.

P0272-Permanent Fault-Injector 4 flow correction value too high or low.

P0500-Temporary fault-Vehicle speed sensor signal incorrect value received.

P1444-Accelerator pedal parameters not learnt.

U1213-Accelerator pedal parameters not learnt.

U1400-Accelerator pedal parameters not learnt.

They cleared all the faults, road tested it and said to bring it back if the faults recur. Testing and reset cost £42. I picked it up, and had no issues on my return.

So I will try to remember to post again if the issues recur.

A failing battery charge level can upset the ECUs. They will then throw codes in their confusion but none of them could be genuine errors.

Lexia would have saved the cost as you can do exactly what the independent did, make a note of the code and then delete.

Only act on any that reoccur because the original fault has been fixed after the batter was changed/charged

True, Lexia would save me the cost of the reset, but at the cost of a Lexia. Another failure and I will get a new battery. The battery is the 9+ years old original, so it owes me nothing.

WOAH! 9 years...in a diesel. That battery needs to go in the hall of fame! I think you are due for another failure.

The only thing wrong with getting a LEXIA is installing the dodgy software. it's a pain. The cost is nothing by comparison to the gain. I bought mine for the equivalent of 30 pound! It has been invaluable to me, however, my little C3 has been...er...a challenge to keep on the road. LOL! If your car is reliable and you cant justify the cost or the learning curve, fair enough.
