    B47 f10 2014 fuel economy

    Not sure I understand what you mean? I'm driving a 520d?! I was struggling to get past mid 30s when I picked it up, which was about 4-5mpg better than the 306hp 3.6 litre V6 petrol E350 I was in before. But after swapping to Shell fuel, adding Archoil 6200eu, replacing filters, breather pipe, new EGR and new O2 sensors it seems to now be closer to 50mpg. I'm running an SE with 245 section tyres as well, I would expect a sport with 275 rears would lose around 5mpg.

    B47 f10 2014 fuel economy

    I swapped over the o2 sensor a while back now and didn't really see any increase in MPG. However, because the hesitation when you hit the throttle sometimes was annoying me I started to look into why, as it never annoyed me on my other BMWs with the ZF8. After lots of diag and live data tracking realised it was the EGR sticking. Anyway, while doing the live data tracking saw the O2 sensor post cat was still showing as failed, open circuit, reading data sometimes but not right. This was weird as it was changed a while back. Anyway, long story short the swapped out the wrong one!!! They had put the new one into the pre car location. They are the same sensor, one with a 350mm cable and one with a 540mm cable. So, I bought a new one and put it in today, but on the drive home, around 16 miles I got over 60mpg, even back home after going back into the city to pick my son up and sat in traffic it was showing 54mpg. Never seen that before. Even if it sits high 40s compared with high 30s I will be chuffed, this is what this car should be about. I will start using it more, I had been using our Discovery as the MPG difference was not all that much! Haha But obviously so many things on these cars that can ruin your MPG.

    Potential F11 buyer- Winter tyres

    Yeah I would be happy with the cross climates too.

    Potential F11 buyer- Winter tyres

    I'm also in Norfolk and have used winter tyres for the last 12 years or so now. The difference between winter tyres is being able to drive pretty much the same as you normally do no matter what the conditions. You need to experience them to get what they offer.

    DAB Signal Drops Out Constantly

    Could also be a build up of grime on the rear window as well, especially on tourings.

    DAB Signal Drops Out Constantly

    The aerial is the rear screen demister, if there is any part of it that is broken in the track or corrosion on the contacts you will weaken the signal greatly when you turn that on. Maybe that is why it is dropping out more in winter, because you're turning on the winter demister more?

    Anyone else got a 528i F11?

    It does the opposite. The N53 is designed to run on 98ron, you can put in 95 ron and it retards the timing to stop knock, but you will lose MPG and BHP running on 95 and it produces more soot too. All official figures are based on running 98/99ron by the way. It burns cleaner on 98 and will be far better for your car long term. It does take 2-3 tanks for it to adapt to 98, the problem is the knock sensors are quite sensitive and they retard the timing even if it is partly diluted with 95, so wait till you are as empty as you dare, and then fill up. Tesco 99 works well with these. I often got a cel light come on for the first couple of tanks, this went away and then I started getting a cel on the odd occasion I had to put 95 in. My 335i dropped over 30hp going from 98 to 95 ron. There were so many who said it was snake oil, but he reality is BMW have run maps for different fuels on their cars for the best part of 30 years now. Evolve did some rolling road tests to prove the fact a few years back. I think I still have the image for the 335i somehwere I will try and dig it out. My old 2.8i Z3 made the most difference, 95 was very tappety, 98 was super smooth and again it was a 20hp drop on 95 ron. For a NA where people spend £10k trying to squeeze 20-30hp more out of their car it is a no brainer. Then consider how much cleaner it burns so far less coking up of internals and it makes no sense not to use it. Then when you add in the fact that the extra cost is balanced out by better MPG and.....well.....what you waiting for?? Edit: I will try and find the one with the 330i N53 if I can. But think I only kept the 335i one as that was my car.

    Replacement manifold thoughts

    I don't think VPower will do much either, but I am sold on Archoil 6200. I cleaned out my manifold on the 530d when I picked it up with 68k miles on it, just before I sold it I blanked the swirl flaps, the manifold I was expecting to be gunked up again with another 53k miles on it, however it was exactly the same as when I had cleaned it before. I also saw my MPG climb from 33 average to 37mpg within about 3 tanks, the car just felt peppier. The other thing was the time between DPF regens too, when I got the car it was trying to do them every 500 miles or so, after using that stuff it would be every 1000 miles at least. I will take a photo of my DPF with 88k miles on it. It had actually failed, it was showing an open circuit, I was expecting it to be gunked up and sticking, presumed that had caused it to burn out, but although it had failed it was clean as a whistle so must have just failed electronically. This is from Archoil on another forum explaining what they are trying to achieve.... We regularly receive questions regarding fuel catalyst technologies and how they work. In particular, the Archoil AR6200. The existing definition of "burn rate modifier" and "lowers burn rate by up to 400 degrees" has caused confusion.In simple terms, a catalyst facilitates a better burn of the fuel. Each fuel type will have a flash point and auto-ignition point, determined by temperature and other factors. This is different to the burn rate.Both petrol and diesel is composed of carbons and these carbons or carbon chains require up to 1200∫F to burn fully. This has nothing to do with the flash point. The flash point is the temperature at which the vapour of the fuel will ignite with the help of an ignition source and the auto-ignition point is the temperature at which the fuel vapour will ignite without an ignition source.Once the fuel has ignited it creates an exothermic reaction (heat). It is this rapid increase in heat that actually burns the fuel (carbons) and creates the explosion in the combustion chamber, thus resulting in a massive release of energy forcing the piston downwards and thus rotating the crank shaft.If you can reduce the temperature at which the carbons burn, say by up to 400∫F in the case of AR6200, you can improve the burn. This is achieved by increasing the surface area of fuel droplets, and starting the burn rate of hydrocarbons at a lower temperature to yield more available BTUís from the combustion process. The fuel becomes more aromatic (increased chemical stability) and a longer residual burn occurs. By commencing the burn rate lower, the lower end hydrocarbons are burnt and the combustion process is more residual and complete, practically eliminating unburned hydrocarbons and wasted energy in the form of black smoke or emissions.Altering the burn rate in this way does not directly increase horse power. It increases the energy release through the explosion, which raises torque output. The result of burning the fuel more fully will also increase torque as well as lower emissions as proven by the AR6200 carbon mass balance tests. This is the same process with all hydrocarbon fuels such as petrol, diesel, ethanol, heating oil, heavy fuel oil etc. It is well worth cleaning your manifold, trying it for 20k miles and then looking again, I think you will be amazed.

    Anyone else got a 528i F11?

    One thing to consider with this is only run it on 98/99ron. They lose around 25hp on 95ron and doesn't burn anywhere near as clean, he rolling roaded it to prove to himself he wasn't imagining it. He said the engine sounded really noise from start up on 95 as well and like a sewing machine on 98 ron. Friend of mine had one of these till very recently, he hated it when his missus used to fill up as she would always put 95 in to save 10p, and it took 2 tanks to get it back feeling right again. He did 130k miles on the same injectors, I wonder if that had something to do with the fact it had 98ron for 99% of it's life?

    Rear brake pads - leg lifted?

    Mine has gone from 30000 miles yesterday to saying 430 miles today on the rears. I'm presuming the sensor has gone through. Also presuming someone reset the rear brakes in the service menu when they weren't actually done.

    Replacement manifold thoughts

    Ford had a massive problem with there 5.7 diesel engines in the states, many used in the services, Fire, Paramedics etc. where they sit idling for hours. EGRs and DPFs etc failing after a few thousand miles. They started using 6200 and they have been fine after 100,000 miles. From 2m44secs, but worth watching the whole thing... I used it on my E61 and at 120k miles it was all clean as a whistle.

    Clean it out and then use Archoil 6200, amazing stuff.

    DAB Signal Drops Out Constantly

    How did you get on with this? The reception on mine is not very good either, LBC is fine, but I have to turn over to Talk Radio when James O'Brien comes on air, and Talk Radio constantly drops out. I'm thinking of fitting a better aerial.
