year 2000 Z3M S50 engine.

I know some of you guys are extremely clever so what are the reasons?

Two years ago I had the number one injector replaced because it showed up faulty on the live data.

My car failed the mot ten days ago and at first they thought it was 02 sensors, but the live data showed injector failure! But what has really got me confused is that it’s the number one again! Now the car hasn’t done a thousand miles in the last two years! And I have run injector cleaner fluid through the petrol tank last year.

any thoughts guys?

TIA

Yes that’s a thought!
