  1. F10 520d Exhaust fumes in cabin

    I am waiting for the weather to improve and then I will remove the cooler. I will post pictures of my findings.

    For anyone that’s interested this is what our LEL meter looks like. We use ours for measuring gasses inside aircraft fuel tanks.
  3. F10 520d Exhaust fumes in cabin

    We have a bit of kit at work called an LEL meter which is designed to detect dangerous gases. Our one has an external probe so can be placed in the tightest of locations. When placed near the two known leaking spots (as I have mentioned about) there is no reading at all. When placed close to the egr cooler it goes crazy and the alarm sounds for dangerous gases detected. There is a crack somewhere on the back of it. I am going to remove the egr cooler and and try to find the crack visually, if I cant then I will pressurise it. If it does not hold pressure then I know there is 100% a leak, in that case I will weld the crack and refit (if I can find it). There is also a chance that the egr cooler case has gone porus. Worse case scenario is a new egr cooler, fortunately I can purchase bmw parts for cost price.

    Thanks for the reply Dave
  6. F10 520d Exhaust fumes in cabin

    So the problem has returned which is really frustrating. After another extensive search to find the problem I have failed to find what the cause is. There are visible exhaust leaks coming from the manifold to the egr supply pipe and also the turbo vane actuator linkage. I have also checked 2 other N47 engines and they all leak at the same place so this isn’t the problem. I am a starting to suspect the EGR cooler as there seems the be a small deposit of soot build up underneath it. I am going to remove and inspect it in the near future. Of course this means draining all the coolant. What I do find strange is that the engine bay has a rubber seal running around the whole circumference effectively sealing it off from the cabin fan intake, why are there fumes getting into it at all? I have confirmed that with the bonnet open zero fumes, bonnet closed slight engine load fumes return. Pictures and more invest to follow shortly if anyone is interested.

  9. Code reader/reset

    Bmw 520d 2012 Has anyone got any recommendations for an OBD2 basic code reader that can also reset engine management lights? There are lots on eBay and not sure which one to go for. I already have a 2012 code reader, it reads codes but fails every time I try to reset the management light.

  11. f10 HID upgrade

    Thanks, I have never coded before, would it be easy to code out bulb errors? I did actually fit some error free reverse led's and it still came up with reverse light failure.
  12. f10 HID upgrade

    Thanks for the input on this guys, can anyone actually recommend a good quality HID kit for the F10? also I want it to look as stock as possible so what colour do bmw use for their factory fitted HID? (4300k, 5000k)
  13. f10 HID upgrade

    Seems like I have started something here! The halogen f10 lights have self leveling lights with projectors anyway so there won't be any dazzling going on. I know now they also need headlight washers but that's just for cleaning. Appreciate peoples thoughts
  14. f10 HID upgrade

    I am thinking of upgrading my standard halogens for a HID kit. There are so many on ebay so any advice on one that works well for an f10? What colour do BMW use in a car that comes with HID's? (4300k, 5000k) thank you!
  15. Here is a few pics of my Mustang and my wifes M135i, love both of these cars very much. The Mustang is so rubbish in many areas but it makes me smile and I love it.
