Hi all, When I fill my car to the first click with diesel, I noticed it leaks fuel for a while. If I fill it to just under full all is ok. Anyone come across this problem as well?

It could be the breather pipe that runs up along the filler... May just need tightening (although some have the breather running inside the filler).

Maybe check the sender unit for leaks where it attaches to tank... HTH ;)

Thanks Dabsy, I think you might have something with the breather pipe because it only ever leaks when its filled right up. Any idea how I get to the breather pipe to check if its loose?

Remove the wheel-arch liner, or you might be able to access it from underneath while its on ramps ;)

Yup, sounds like what Dabsy said or a small leak in the connection between the tank and the filler cap which is not obvious when your filling as the flow of the fuel is fast enough not to leak through.

Either way, worth a look yourself! follow the advice Dabsy gave above. I would.

      Collision Avoidance System

      Thank you for your response Dave, I have been to BMW Dealer but all they say computer indicates 'no faults' although I had frequent warnings saying system was restricted. They refuse to road test it saying it is dangerous to road test which I dispute as the system should give a visual warning at 8 car lengths and low speeds. I suggested to test it against another BMW with the same system but again they will not. If I have it on the most sensitive setting and get no warnings what is the point of the less sensitive settings. Lots of unanswered questions with this system?

      Engine running weird when hot

      Morning Billy You need a diagnostic session to narrow things down, at 161k I would also carry out a compression test and check fuel delivery and pressure. Your symptoms could be an accumulation of things or as simple as a dying throttle body diagnostics will help Dave

      BMW X1 Fuel sensor failure.

      Hello. If you own or use a BMW with a diesel engine, manufactured since 2006, a faulty fuel line with an integrated temperature sensor is most likely installed in the engine compartment of your car. This sensor becomes unsealed and injects fuel through the electrical wires via the plug, as a result of which the entire installation (harness), controllers (including turbines) and the ECU (computer) are damaged. Failure may occur after approximately 40,000 km. The costs associated with purchasing the above-mentioned parts amount on average to 4000 euro or more + service, but this repair does not solve the problem because the new temperature sensor still has the same defect. Below are some links to videos in which mechanics describe this problem. I have developed an effective protection that prevents fuel from entering despite a faulty sensor, which permanently solves the problem. If you are interested, please contact me by e-mail for more details: [email protected] Product made in Poland YouTube Links: https://youtu.be/5za5VP0wqkQ?si=jR9S4GCRW6gn7XOU https://youtu.be/kVobw7st0H0?si=aS2ZO6ab1jAWgSI- English: https://youtu.be/aR4rDtD7h7c?si=ze-BBAmBhpH7qwrM

      Engine running weird when hot

      Hello everyone, got a 116i m sport n43b20a. Had it for about 3 months and soon after buying noticed a wierd problem. When cold the car would run perfectly, however when warm or stuck in traffic you could feel it become a little bit rough, sort of a banging feel from the engine which you can feel through the car. When doing this, when driving it runs perfectly. However when you attempt to pull away, the car will drop to around 400rpm and pull away a bit bouncy, having to give it more accelerator to prevent it from stalling, whenever in reverse it does this and normally leads to stalling. Over the last 3 months it hasn’t gotten worse but it does the pulling away thing when it is cold now. Had a service >1k miles ago with plugs. Also had it smoke tested and no signs of any leaks. Does anyone have any advice or had a similar story? Cars on 161k Thanks
