Well you may have to change the O2 sensor this seems to cause this fault,I think we had a tread about this a while ago.

Yes just checked past posts and it seems changing the O2 sensor cures this.

I was thinking the same,after injector change perhaps O2 is contaminated or damaged...

Hi everybody,after lambda replacement no errors for a week and 2626 came back on together with 2024,2025,2355,2032,0100 and 2024.Im running out of ideas what’s happening.Could the battery be the problem?Still on the original near 15 years old..went flat leaving it for couple of weeks without driving..what else could I be?noticed that there is black smoke after injector change.did drive the car with faulty injector for about 100 miles..could it be worn cylinder?
