On September/October 2021, all stocks of new injectors for N43/N53 series engines were sold out. In December 2021, the backorder was around 16’000 units. At the end of the year, the injectors for N54/N63 series engines were sold out.

The situation in the middle of January 2022 (BMW dealer network):
a. the backorder for N43/N53 series engines – around 22’000 units;
b. the backorder for N54/N63 series engines – around 12’000 units.
Deliveries confirmed for around 600 injectors (middle/end of February). This amount can be taken seriously. In addition, these injectors will be received by the customers, which are “closer” (it means customers of Greman dealers) and are at the beginning of the line.

What NOT to do:
a. add any “cleaning” additives to the fuel. These additives will soften the oxide and other dirt from the fuel tank; they will get stuck in the nozzles or the injectors and be damaged entirely. In the case of Piezo injectors, these additives can NOT be used!
b. do not give your injectors for “cleaning”! After cleaning, the situation will only get worse! The reason – as the cleaning fluid in the cleaning stands is not replaced after cleaning each injector (it is expensive) – this widely used cleaning can not be used for Piezo injectors (due to microscopic openings of the nozzles)!
