Such injectors were delivered to the BMW user:

The first injector – manufactured 8 years ago and “refurbished.”
Second and third: China fake – inappropriate body color, inappropriate manufacturing data.
Are these three good-quality injectors? No, the waste bin is the appropriate place for these “products”.
But the seller looks excellent! Really?
I will not mention an exact web address because I don’t have 100% proof that this purchase was actually made via this webpage. I will mention only one thing which I find suspicious.
a. when checking the address of the seller via Google, I have to conclude that it is not the factory (as could be guessed by impressive images on the website) but a very modest private house;
b. the fax number indicated is not valid;
c. indicated person in charge… Sounds like the inhabitant of a completely different part of the world. Yes, globalization is comprehensive, but – this obstacle looks suspicious to me;
d. the label, which you see on the 1st injector, is 1:1 as the labels previously seen on Diesel Fixneuss “products”.
I assume that this company was established for a single purpose – to resell the injectors “manufactured” by other (with low reliability) manufacturers/sellers. This is a very popular tactic, for example, in the market of NOx sensors. It is as if “reliable” companies registered in Germany are reselling cheap Chinese fakes with a huge margin. And they do it successfully because the people trust them – it is not China; it is a “reliable” company from Germany!
Be very critical by choosing the seller of the injectors. Don’t risk – purchase them only from BWM AG!
