Do they sound different at all Phil? Or any difference in power delivery? Or literally no difference? Glad its worked out.

TBH no. Same sound, same feel. I did wonder if they felt a bit spicier at WOT, but it could be my imagination. Since the ECU tells the injectors precisely how much fuel each cylinder needs, the fact that the injector is capable of delivering more (when fitted to an N54) is irrelevant I guess...

Any idea what the going rate for that sort of thing would be?

I presume the car is completely undrivable until they're coded in? Or could I limp to the Indy provided it's nearby after fitting them myself?

The re-coding should be a half hour labour max. If you're asking an indy to do just the re-coding, make sure you note the individual injector values as you fit them. Yes the car will drive without coding, though it might be a bit rough to start with, as the car adapts to the new injectors.

It is about 5 minutes of work for someone that knows what they are doing to be honest. The car will drive if you change them yourself.

Just FYI - you do need to drive in a certain way immediately after the adaptions have been cleared to help the re learning process. It depends if the indy includes this in the time taken to clear them or not. You can get most of the way there to re learning the adaptions after an hour.

As I said in the other thread I reccomend doing this and addressing any other faults before you take the plunge on a new set of injectors anyway, as it can sort some rough running and cold start wobble but a bit tricky if you don't have the software (which isn't expensive to buy either, about 25 for a cable). Depends how involved you want to get.

That's interesting, I don't have the software, unless it can be done through protool. I'm definitely willing to get involved, but trying to figure out even how to install ISTA which I presume is what's required is quite difficult for a newbie to get through and ignore the incorrect places to acquire it.

Infact I just checked and programming the injectors is doable through protool, so surely resetting the adaptations is possible too.

Can anybody speak from experience on that?

Very interesting! I'm in the same position having almost given up on finding index 11s. Had seen comments previously saying index 12 in an N53 is a bad idea but maybe it's worth it then seeing as it's impossible to source any 11s.

I can't say anything for protool as I've never gone that route but I'd strongly recommend getting a cheap OBD cable and getting ISTA/INPA. Personally, I've only used INPA as bimmerprofs is full of helpful guides, all be it with some questionable English at times. It's amazing the detail you can go to with it, I can see all the adaptions for the injectors. With that, I am thinking I might be able to get away with just replacing one bank with 11s/12s and putting all the supposedly good ones in the other bank till my wallet is looking healthy again.

With regards to coding/re-adaptation, it should be a breeze if you are technically inclined. I'd look at [https://bimmerprofs.com/injectors-adaptations-coding/] for some insight on the current injectors and possibly [https://bimmerprofs.com/not-encode-injectors/] for some help on coding although I haven't looked at that properly I'm sure there are loads of guides out there.

With regards to re-adaptations, this guide is all you need [https://bimmerprofs.com/re-adaptation-engine/]

I got all the tools from [https://www.bimmergeeks.net/downloads] and [https://bimmerprofs.com/msd80-loader-2-023/] update package as well.

Hope that helps and I haven't hijacked the thread too much but I'm glad the index 12s could give me hope!! Reply or DM if you need help, I should probably get back to work for now!

I have installed both ISTA and INPA. Both are easy to use and readily available and a must have if you want to get involved.

For day to day fault checking I use carly - but got it before it was a subscription service and don't use it enough to warrant the subscription cost. It just saves getting out the laptop and I keep my dongle in the glove box if there is ever a fault when driving.

Hey! First of all, thanks for sharing your experience!

I wanted to ask you if your car is still well up and running with those N54 Injectors? Im about to do the same, just with used ones (from a N63 actually) because you literally can't get them new.

Yes my N54 (index 12) injectors are performing just fine. However mine were new not used.

Cool! How many kilometers have you driven since? I got mine in now and it performs awesome. Apparently my head gasket starts leaking, though..

I've now driven 7,000kms on the N54 injectors. I presume you mean the valve cover gasket is leaking, not the head gasket? Head gaskets are not known to leak on this engine...

I already replaced the valve cover gasket last year

My Engine has about 280.000km now, and it started smoking white, funny sweet smelling since a few days. Today it started smoking non stop.. not sure what to do now. Most likely the head gasket

That's bad news and very rare. Hope you manage to get it sorted...

I'd be looking for a proper test before condemning the HG. Also they tend to get damaged rather than fail so has it overheated recently? If it really is burning coolant it'll not do your cats and o2s much good.

I was at a workshop and they did a pressure test, its definitely not holding pressure so there has to be a leak somewhere (and it does not seem to be on the outside).

The Engine didn't overheat to my knowledge, i did a test drive today and it was holding the heat perfectly fine! (Range is 90-110C, both oil and coolant). Also no smoke today, its really weird!

Any gasses in coolant? Compression test done?

What does not holding pressure mean - sounds like vacuum test on coolant system - as Phil says, HGF unheard of on these engines

The coolant smells like exhaust, Compression test hasn't been done yet - was thinking of buying a tester lately

By not holding pressure i mean, that a device was connected to the Coolant expansion tank cap to build pressure (1.5 bar) and you could watch it get lower by the minute

There were no signs of coolant in oil or vice versa so far

HGF might be unlikely, but i heard of lots of cases of cracked cylinder walls
