£288 per injector

This is by far the cheapest and comes from a reputable supplier in UK.

BMW stopped them being sold in 2020 via the OE supplier but it looks like the Continental creation/sale of Vitesci technologies has opened up a new route to market outside of BMW.

The injector has BMW marking underneath the plastic sticky label and is coming directly from the manufacturer who produce the injector, they are not refurbished or knock off they are geniune from the original manufacturer(aka Continental/VDO). As such waranty is direct with PFJones not BMW.

These are genuine VDO injectors but VDO has spun off their business into a new company called Vitesco Industries.

And

These are the cheapest BMW genuine from a BMW dealer

Thanks for the info. Pity P F Jones don't appear to supply the injectors for the N54 engine (13538616079). It's a later iteration (index 12) than the N53 injector with further improvements and fits the N53 engine without issues. I've had N54 injectors in my N53 for 20,000 miles without a problem.

Personally I wouldn’t recommend going index 12 n54 injectors on a n53 they were released at the same time as index 11 n53 so it not like index 12 n54 is better than index 11 n53 (a common misconception though) and there is obviously a technical difference between the platforms which resulted in a different injector.

As to whether they work or if there are any issues it’s hard to know the real answer unless your bmw/continental engineer, al we can tell is BMW/vdo chose to keep 2 separate product lines. N54 demands more fuel and conversely n53 demands less fuel particularly when running stratified.

It’s abit like using ferrar 599 injecectors In s65/s85 they fit but to get them to work optimally you need to change the fuel maps.
