    N53 Injector - BMW Supply Issues?

    Completely different unfortunately! n53 use piezo crystals and I wouldnt be surprised if thats where the shortage is. Reminds me though, OP if you are *really* stuck n54 injectors work apparently. I wouldnt, personally, though!

    N53 Injector - BMW Supply Issues?

    Doesn't sound good. If the plugs are wet with petrol when its sat overnight its a dead cert they are leaking ... Good luck finding some, defo try e90post - sometimes they pop up in the for sale section. I'd not rule out second hand index 11 at all (they still fail btw, obviously, but seem more reliable). Also wouldn't worry about mixing old and new. See bimmerprofs website for more info on injectors.

    Yeah I only ever put e5 in mine for the same reason. Is yours misfiring or playing up though? Cold mornings will show up a problem, otherwise wouldn't overly worry about it.

    N53 Injector - BMW Supply Issues?

    I've heard of this too and apart from ebay I have no idea what the options could be. Interesting that yours were index 8 - I had mine replaced to index 11 around 2016 timeframe and was sure index 09 had come out of it (12MY). Not sure it matters, just interesting. If you need them I think ebay is your best bet or ask on e90post with a wanted ad - more n53 owners over there.

    Various queries 530i M Sport

    Which engine is this? If its a late n52 or an n53 the breather is in the cam cover and you need to replace the whole cam cover, OR, just replace the CCV diaphram part. They are usually noisy when they fail though.
  6. Interesting, thanks for updating us. Perhaps an internal fault or just normal failure for AGM batteries where internal resistance drops and so the voltage increases (or the other way round?! - half asleep). Good to watch out for.
  7. I'd not worry too much personally. Charging is computer controlled and takes into account load and temperature. Ive seen my ctek pushing out more than 15v on AGM setting and its supposedly a super dooper charger.

    Front Brake Discs

    Wow didn't realise you could leave the carriers on either. Must be to speed up brake jobs in the dealers. Also saves buying the carrier bolts. ETA i think that means the carrier doesn't need to come off for front wheel bearing replacement either.
  9. AFAIK the alternator shouldn't overcharge What was the actual voltage? If its close to 14.85v i wouldn't worry too much. You didn't have it on a charger at the time did you ? Or was it just the engine running and idling?

    5w30 or 5w40 n47

    My n53 just had 6.6 of Millers Oils XF Premium C3 5W-40 5W40 Fully Synthetic Engine Oil, less than £52 for 10 litres delivered from sunny Cornwall. Engines never sounded better. And yes, i'm deeply sceptical of such claims too.

    Heavy rain, Water leak

    Thanks Andrew. Also the grommet cover needs to be modified (@GJP_1987 photo credit) as the rubber gasket blocks the drainage channel - thats a factory fault. I also drilled extra holes, but mine run along the drainage channel and are larger, but everything helps - get the water away from that grommet/space as quickly as possible and allow crud to be taken with it.

    Heavy rain, Water leak

    The panel has to be modified as well as replace the grommet IMO. It is no good replacing the grommet but still having detritus build up and hold water in that space. Its a poor design, and certainly looks like an afterthought.
  13. You sure its not burning oil smell? Oil leaks from the cam cover onto the exhaust, and can stink. Check engine for leaks above manifold.. not sure about cracks but anything is possible.

    ERHC/VDC Harsh ride

    Does it make a difference if you turn traction control/DTC thingie off completely? Long hold the DTC button I should add - no experience with VDC as i don't have it. I am just curious if the DTC thing makes a difference.
  15. @leew88how sooty does your exhaust get at its worst out of interest? With mine I can run my finger around the inner circumference of a tailpipe and its a light dusting, not caked.
