I replaced the damn injectors, all 4 of them in 2012.
Now it seems they all failed around the same time and i had to replace injectors for cylinder 1 and 4 one month ago. After 2 weeks injectors in cylinders 2 and 4 failed so i replaced the other 2 as well.
Now, after a month it looks like the injector cylinder one is around 4.60-4.80 according to INPA live data so i am assuming it is going to fail soon.
Please note that the replacement injectors were from a 530D or 535D which had only 10k on the dash.
I asked the mechanic why did the injectors fail one month ago and he said most probably i was ripped off back in 2012. I wasn't as i have my readings and the injectors were spot on. So he said maybe bad fuel. I use premium diesel double filtered.
So, the question is,what would cause injectors to fail in such a short time?
I have an error concerning the particle filter 4CE0 and also 4530 and 3F57, for which i'm expecting a used turbo with low mileage to test.

Looking forward to your help guys.

Thanks
