Since the VW emissions fiasco, In Europe at least, the authorities introduced a revised standard for emissions testing - WLTP which is based on a much closer to reality test. The old system, NEDC, was too far from reality and seriously exaggerated MPG claims. So, with WLTP it now looks like cars are achieving less MPG but in reality it is a more accurate number. As an example, my 640i is specified by BMW (WLTP), for the combined cycle, as achieving around 30MPG, Over the last 8000 miles I have achieved 31MPG so very close. Note that this changed in 2017 so older cars show NEDC MPG figures and newer cars of the same model may be showing WLTP figures making the older cars look more efficient which is not the case.

Other than "possibly" better additives that "may" keep the injectors cleaner you "are probably" just wasting your money in my opinion. It'll do nothing to prevent the clogging up of the EGR and Inlet Manifold as that is all post-burn. Keep the car regularly serviced and save the fuel money.

They do Goodyear Excellence in Run flat. This is what I had in my F11 from factory. Great tyres on that application.

No, ESYS will not be happy as the components for the option you're trying to delete are still registering to the crash module. Don't try the quick and dirty, do the full job to prevent ongoing issues.

Have you seen this instruction set: https://www.newtis.info/tisv2/a/en/f10-530d-lim/repair-manuals/51-body-equipment/51-12-rear-bumper/Bz8UByZy

From what I've seen, VDC is a very rare option to be found on AUC cars, you may be waiting for a long time and It is very good at smoothing the rough and then firming up in sport mode though and you need to be happy with the car you buy and the way it drives. Make sure you have a decent test drive over different road surfaces. My old F11 didn't have VDC and I loved driving that car, the suspension never bothered me.

I understand. As far as I'm aware, there is no way to change that behaviour on the 6WB cluster.

Unrelated to the quality of drive, if you were to get BMW to swap the 20s for 19s, the vehicle factory option list will still show that the car should be running on 20s. Just something to consider when selling the car onwards in the future.

Mph doesn’t work with the digital cluster 6WB as you already have the digital readout available.

I removed and cleaned my inlet manifold as preventative maintenance as I had seen a swirlflap error in ISTA. See my forum topic here:

@bestdj and @Jimbo07g41 Sorry guys. I got that one wrong. I do remember now, uploading the files to the harddisk - the files go in folders and it is a very analogue process accessing the music through those individual folders. I use this tool that a chap wrote: https://www.ericdaugherty.com/dev/itunesexport/ to export the iTunes (assuming you're Apple/iTunes users) Playlists with the right folder structure along with the album art. I've been using this on a USB stick plugged into the armrest USB port for many years in the 3 BMWs we've owned and it works perfectly accessed via the iDrive.

Have your inlet manifold removed and mechanically cleaned. The swirlflaps are sticking due to a build up of carbon deposits around them.

You can only import from CD to the internal harddrive in the Professional Nav System. Use the USB rather than the internal harddrive. Just leave the USB stick plugged in to the armrest USB port and play from there.

To backup the CAFD files prior to coding, follow the steps I provided you in my previous post: FSC files are feature enabling files. They provide the license from BMW to run certain functions in your car. Don't touch the FSC codes. The only one you can influence is the SatNav one. THat's another lesson for another day.
