Ye thats great, that was what I was hoping to hear. Think will just have to go for it and hope for the best, at least with buying new get 2 years guarantee with them.

Another day another dud injector for me... This time going down an incline at 50 mph with only slight accelerator pressure. It lost power and stuttered for a few seconds before the glow plug light started flashing. It's the #2 injector, which I replaced with an 03L130277S 2 years (17,000 miles) ago. The injector was second hand, but only 2 years old from the date stamp at the time I bought it so I assume it's managed less than 40 k miles overall. Pants.

Anyway, when I have time I'll hack it apart to try to see what the difference is between this and the B variant. This might give a clue as to the failure cause. Not that it really matters... As a final hack, I'm going to try unscrewing the piezo actuator in-situ and replacing just that, without removing the whole injector, Just to see if it's possible. This would make it a far easier road-side fix.

Meanwhile, my #1 injector's on 165,000 miles now and still going strong. How is this possible?
