  1. Fitted silicon wiper blades as the old ones were on their way out. Can't really comment on how much better they are as any new wiper blades would be an improvement but the silicon ones are supposed to be more durable and more resilience to colder weather. I will need to re-coat the windscreen soon too as itd no longer beading.

    F11 rear tyre wear problem

    Go to a specialist who deal with wheel alignments. You would spend no where near a third for that for all four corners and you would have it done properly as that quote is clearly a rip. I would also recommend get the wheels rebalanced as well. You will notice an improvement in handling.
  3. I think Eco Pro works extremely well. Yeah its like driving a barge but its meant for improving mileage. The most I have managed out of the tank upon hitting empty was 745 miles. Normally its about 420 miles for half a tank as that is when I usually fill to full. The best figure I have seen for the bonus range was 230 miles. Normally its about 140 miles. I have the air conditioning on constantly but its mostly on the lowest setting so. The start/stop function definitely makes a difference. However I always check tyre pressures, recently changed all the filters, do regular oil changes and keep the clutter to a minimum as well as keeping a record of each time I fuel up. Sad, I know. The weekends are for Sport mode. Oh yes. (Yeah, its all in km. I prefer km, easier to keep track of mileage and fuel consumption. Plus the numbers move quicker.)

    KDS / Alignment question

    Getting the wheels aligned is probably one of the best things you can do. It is definitely worth it, not just for tyre wear but also for handling. I would also suggest getting the wheels rebalanced. You may find you only need to have one wheel done if any do need rebalanced but you will notice the difference straight away. I had one done for less than £20. The rest were checked for nothing as they did not need adjusting.
  5. Replaced cabin filter and air filter. Both were pretty black and filled with debris. The cabin filters took like two seconds to swap but damn that design. Took like forty minutes to undo and redo the panels and lid to get at them. Never want to do that again.
  6. Changing the gearbox oil isn't any more difficult than the engine oil, its just more time consuming because the car needs to be elevated with four axle stands and the whole middle panel needs to be removed. One annoying thing I did find is that there is a non-movable thin metal bracket that holds the panel and it is placed right in front of the fill bolt. Easy enough to get around with the flexible hose on the pump but it scratched the hell out of my torque wrench I did wing it a bit as there was nothing to indicate which gearbox it was for the torque values, just spurious codes, so based it on the GS6-45DZ from pictures on eBay. The gearbox fitted to mine, the fill bolt is a T50, not a HX8 like the drain bolt. Overall I would say its worth doing as preventative maintenance. I bought two 1 litre bottles for £35 and used about 1.3 litres. The differential on the other hand: why does mine not have a drain plug! Had to pull out the oil with the pump.
  7. I stopped about twice at services to inflate it and it hadn't lost that much air. Thankfully I was able to get it replaced that weekend. It was a bit risky but I figured if the tyre stays within the pressure range it should be fine. I don't know. They also put broken glass along the bottom edge fence which resulted in an annoying vet bill. Something something misery guts.

    Ah right. I must be the only person I know with a BMW that doesn't have it. Always behind the curve.
  9. I followed this: https://www.newtis.info/tisv2/a/en/f10-520d-lim/repair-manuals/23-manual-gearbox/23-00-manual-gearbox/1VnYc440mD I use this which I also use for the differential: https://www.bavauto.com/b8800003 There is no filter to change on this particular gearbox.

    RED X?

    Drain tank to reserve, fill up to full with premium fuel, perform an Italian tune up, then back to the cheapest fuel. You are paying like £20 a litre for RedX. That would get you at least 14 litres of premium fuel. The only way you can truly get any performance back is to actually physically clean the engine. I did this with 2 strokes, rebuilt the engines, cleaned out the power valves, decoked the expansion chambers, polished up the cylinder heads and put in fresh spark plugs. The response from the engines afterwards was incredible. There would have been no way that anything like RedX would have made a dent to the build up carbon. I haven't had the chance to do this with a 4 stroke engine, mostly because I don't have the tools.
  11. I have a mini compressor I got for free. Used it once on a 400 mile journey after I discovered that my neighbour had put nails under my wheels again for a third time. The manual states to not exceed 50 mph for a short distance or whatever but if the tyre is constantly pumped up as its a slow puncture before the warning comes on, then it should be fine. That's what I did. I'm not dragging out a six hour journey. Its long enough.
  12. Put in fresh gearbox oil. Lifetime fluid... yeah right! The oil that came out was like chocolate milk and that was at 55,000 miles!

    How come my F10 doesn't list service history in iDrive but others do?
  14. Have you had the wheels rebalanced? I had an issue where I would feel a little vibration on the steering wheel. Turned out one of the wheels was unbalanced and acted like an oval because all of the weight was on one area. I went to a specialist as very few places offer precise wheel balancing and they used a computerised balancing machine and spun round the tyre and reset it on the rim. Standard tyre shops just stick on the tyre and put a weight on the opposing side of where it is heavy. It was like driving a different car afterwards, it was that noticeable.
  15. I'll need my binoculars to see that one if its the only one.
