  1. Talking from my own experience, I had ignored various intermittent NOX fault codes for years, never caused any rough running or other noticeable running issues or EML light. It was only will I did further investigation that I realised Stratified mode was unavailable for the whole duration of the issue and as you're aware this means reduced fuel consumption due to the engine running in emergency homogeneous mode. Since I rectified the issue by going the aftermarket route (NOXEM) I have noticed an improvement of around 4 mpg which is about right considering that stratified gives an improvement of up to 13% over the non-direct injected models. I would say that if your mainly using your car for town work and your driving style doesn't justify it then you can hold off for now. Since your fault code points to the NOX sensor itself I assume there is nothing wrong with the electronics part, so maybe worth a clean-up.

    Remote coding of cars

    Not used an ethernet based OBD before but I assume it will be step up from a standard USB OBD. I would test connectivity first by using some non intrusive ie inpa then flash upgrade a non critical module first such as DAB module.

    Without the correct cable you will have issues like I'd explained even if someone did it remotely for you.

    Is ISTA P safe to use and update

    Not being harsh, you are going to run into issues doing whole car software update using D/K Can cable, worst case your car won't start as some module with fail with signature check errors rendering you car useless. The entertainment module on the MOST bus would most probably fail, even if it was successfully you're looking at 10-12 hrs to flash the entertainment modules alone. Some modules I've successfully flashed using D/K CAN OBD cable are DME, EGS, DAB, because I have done a lot of research on the coding forums which ones to avoid one of them is the GWE gearshift module on LCI which fails and subsequently bricks your ECU. Get a proper cable such as ICON and a power supply if you want it done properly.

    Remote coding of cars

    I've been playing around with INPA, DIS, NCSEXPERT, WINKFP for many year on my own car, done loads of coding and some programming (Winkfp flash), done some LCI SAT sports auto conversion for some dude over in Sweden which includes EGS flash to sports firmware and coding and a few others in the UK. The reason why I say some programming is because I use a D/K-CAN OBD cable and you have to be very careful as not every module can be successfully flashed with this cable. I only flash the modules that I know would be successful such as DME, EGS, DAB, I've not yet flashed other modules because I simply don't want to take the risk. The entertainment modules (ones on the MOST bus) are known to fail with OBD cable and even if it was successfully can take you around 10-12hrs alone! If you want to you whole car updated then invest in a proper ICOM cable and use the MOST optical interface to update the entertainment modules, but for general coding the D/K-CAN OBD cable is fine. A power supply is also a must, but you can get away using jump leads connected to another car with engine running for a short term solution.

    Cylinder 2 misfire 30i N53

    Bank 2 upstream CAT (nearest to engine) is aging judging by 29F5 code. In regards to Cyl 2 misfire, you need to read real-time diags to see what it's doing, specifically check the STFT / LTFT and also look at the rough running measurements etc. These engines are hard to diagnose just by looking at a F/C you need to read in real-time.

    Sat Nav Disc

    I have the same problem when using "copied" Nav disc, once the unit gets hot it fails to read the disc. No problem with the original disc though so I suspect the laser in the unit is getting weak due to wear and tear.

    E60 cold start problems.

    Search manually rather than putting in your reg eg BMW, 5 Series, engine, year etc. Then it's under Engine parts / Fuel & Engine Management / Fuel Injectors. Product code is 431110560

    E60 cold start problems.

    Does he offer any warranty? ECP has them for sale at £305 per injector, use their discount code 35% off so £200 but with warranty and they are very good for no quibble returns. Carpartsforless also do them for the same price.

    E60 cold start problems.

    It's like most things, heat metal expansion reduces the tolerances for the leak to happen. Also when left overnight the weeping injectors flood your cylinders hence poor initial cold start / misfire.

    E60 cold start problems.

    I know your pain, unfortunately the early version of the N53 injectors (pre rev 11) are known to fail in a short amount of time which has no relation to the overall condition of the car. My personally recommendation is not to use 2nd hand injectors if you intend to keep your car. Unlike conventional solenoid injectors which respond well to ultrasonic cleaning, the N53 high pressure piezo injectors cannot be refurbished if leaking. Just bit the bullet and source rev 11 injectors which have an improved design which and shouldn't fail prematurely.

    E60 cold start problems.

    If you are mechanically minded you can do it yourself it's not too difficult plenty of guides on youtube, make a note of the flow rates etc printed on the new injectors then take it to an indy to code the new injectors. Injector cleaner won't fix the fault as it's leaking from the seals not blocked.

    E60 cold start problems.

    All the symptoms and F/C points to failed injectors, this is the number 1 common issue with the N53 direct injection engine, which in turns kills your NOX sensor and that part alone is £450 down the drain so I would advise not to drive it until it's fixed.

    Cylinder 2 misfire 30i N53

    Any other codes apart from Cyl 2 mis-fire? Also if you have your own INPA diags and willing to capture the screenshots yourself use this guy, he is offering free remote diagnostics. I bought the NOXEM from him and he is extremely knowledgeable on the N53 engine. https://bimmerprofs.com/online-diagnostics-n43n53/
