Another diesel thread! White-ish smoke, with a weird twist

Still not convinced about code for injector rather than car. Why would the codes be on the rocker cover ie each cylinder.

It’s so you can see them without taking the injectors out- the code’ll be printed on the injectors too but on mine at least you can’t see it all without taking the car to bits first.

The main purpose of the label, is for programming in the factory.

Engines come fully assembled from the powertrain factory with the injectors already in, and they need some way to get the injector codes into the ECU in whatever vehicle the engine ends up in. For this they add a nice barcode label, then simply scan it during final coding.

The official line is you should remove the label if you change any injectors, so as to avoid confusion to any subsequent person trying to repair it.

Can you see the “smooth running” adaption values with your scan tool on the OBD port??

Hi Maxtorque- unsure, but, it is fixed or at least running well. Just remains to do some dickering with the injector seller.

I’m not delighted about the recon injector still having its original code. So half tempted to pop in and get it tested and a new code generated if appropriate, since there’s obviously room for maneouvre between “exactly right” and “good enough that there’s either no issues or none you can identify”. Having said that, it’s a 120000 mile old car so probably nothing else on the thing is exactly right either.

But that’s it all diagnosed- original fault down to leaky injector, second fault down to faulty replacement. Lingering smell of hot oil down to me pouring diesel absolutely everywhere. Slight eau de sweaty balls attributable to filling car with river.
