Next Chapter!!!
Ok then folks, Hope you have got your thinking Caps on . After a chat with the Dark Lord himself (Thanks Darren I appreciated your time) I was quite satisfied to settle for the consensus of opinion that when a knock code is set, that the offending cylinder should be considered the cylinder in firing order. i.e. when cylinder 3 knock threshold code is set, it actually means the third cylinder to fire. So that would make it cylinder 4. . I was so satisfied in fact that I recalled one of the Mondeo's to set right my mistake. Anyway, bearing in mind that I have had two of these in now & fitted injectors in both of them, after noting a P2338 cyl 3 knock limit exceeded. I should also say that I did recode them & clear the light & only when they came back a week later with the same code & a nasty knock did I advise the replacement of the injector. Anyway I apparently have made the mistake of replacing number 3 injector in cylinder three, when according to general opinion I should have replaced the injector in cylinder number 4. (Still with me) Right, now that’s clear in your minds. I recalled the first Mondeo that had a new injector & after a lot of buggering about at the dealers & going through their returns bin. I found the original injector (identifiable by its coding). I was thinking that if I fit this injector back into its original hole & see how it sounds. So now it’s back in the same state that it was originally presented to me & coded using the Snap on simple method. I started it & it sounded absolutely awful, like a piston was broken. I know about the lack of pilot & post injection after recoding, but this was worse than ever. I entered the correction codes in the way AutoDiagnos suggest & it was still terrible. Next I fitted the new injector into cylinder 4 the one that I should have done originally (allegedly & still up for debate). After I coded it in (both ways) & still it sounds terrible. I have been on a 15-mile road test & it’s still noisy. Bare in mind also, that when I originally replaced the injector, it was 90% quieter upon start-up, without actually coding anything. Now I am in a right conundrum. I have the top diagnostic guys in the UK explaining one method & of interpreting a knock code & the dealer guys & many other diesel specialists & now my own evidence, telling me the opposite. Both of these 2002 (code 8) Mondeo’s have been back with the customers now for a few weeks & have not logged a knock code or given the customer cause for concern. So it looks to me that the knock code does identify the cylinder in a conventional manner & not as suggested by many guys on here. Trying to keep this short & to the point honest. I also unplugged the injector in the third cylinder from the front pulley, to induce a circuit code & P0203 injector circuit malfunction cylinder 3 was logged. I find it hard to believe that different methods of cylinder identification would be employed for the purposes of diagnosis. In summary, I believe that the evidence shows, that a knock code relating to a specific cylinder, actually applies to that cylinder, as conventionally considered. The only area left uncertain is which method the various scan tools use for entering the correction codes. As I write this, I am still unsure which way my kit does it, because when I originally saw these Mondeo’s, I recoded all of them & as such, it wouldn’t have mattered if I were right or wrong in my entry method. The next time I see one I will take the time to pin down the correct method. On this last Occasion however, I did enter the codes in the way Tony Vamplew mentioned & it does sound ok. Apologies’ fellas for the long winded post All the best Dave Hill
