Oilburner

On my 2014 520d F11 the fuel filter change is approx 37,000 miles, and I'm currently on 30,000 miles I will probably do my own at 35,000 miles, I would say as your vehicle is only at 19000 miles it does not want changing, I can't see diesel filter being that different to a petrol filter as far as service interval.

Looking at your piston ring in the photo's it does appear damaged, I would also suggest checking the cylinder bore for any damage, in the video it does state the bore is tapered towards the top. Whilst the video relates to a Wabco compressor pump from a Range Rover the internals are the same repair procedure, there are others on youtube showing the repair procedure as well, I have not done a reseal myself but it looks really simple to do, you could also speak to the supplier of the seal kit for further advise. https://www.youtube.com/watch?v=gK5hkM0iVVo Also check the solenoid on the pump in this video it shows the solenoid had rusted up and seized he shows how he freed it up only after fitting a complete pump, I don't know if that part is available separately. https://www.youtube.com/watch?v=M_VxT6h5bQE https://www.youtube.com/watch?v=JgVmnN5rrrs

Just need to think how to properly treat the rust on the roll bars, open to advice. You could get the roll bars shot blasted and then powder coated, lots of suspension springs are powder coated so it's very durable.

@Dustybin850 - Replacement compressor seal kits are available for the wabco compressor online. http://4x4airseals.com/product/bmw-5-7-series-f01-f02-f04-f07-gt-f11-air-suspension-compressor-piston-seal-kit

@535iAndrew Looks like you are going to be busy with those shiny bits. You made me laugh with your trailer loaded up I thought you had been sweeping your chimney and you had a load of soot in there, knowing you burn lots of logs.

That's a shame it did not show any ingress of water, I would agree with the garage its running down the wiring from somewhere and that was the most likely place, very puzzling where it could be coming from. Keeps us informed when you manage to trace the water ingress, good luck hope you find it soon. PS- As this is quite old topic now you may have managed to find the leak, but I only just saw your notification today when I just signed in.

Looks like SOS call system failure can be coded out, on youtube I found there are several different ways of doing it. https://www.youtube.com/watch?v=vGx7SI2Coaw

Surprising what you can find when have a lot of time on your hands.

Whilst in this video it shows a BMW Series 120d N47 engine timing chain replacement, at different parts of video they show old parts and new parts, it was interesting to note the old timing chain compared to the new chain had not stretched that much, but the chain tensioner comparison there was huge difference.

I don't know if this is any help is any help to you, the guy shows in the video how to determine if the timing chain is slack in a BMW N47 engine using a PicoScope 2204, the video makes interesting viewing how to determine if the chain is slack, especially if the chain noise is still not obvious.

That's a lot cheaper than £1400 for the BMW mini N47 engine timing chain issue replacement, I just hope my wife's mini cooper d 1.6 with the BMW N47 engine apparently they can go in as little as 60k, this is not good having two vehicles that can suffer the same timing chain premature failure, hopefully as I have always changed the engine oil on both vehicles at 10k or less, hopefully these failures won't occur to me and as current miles for F11 is only 30k and mini is just 50K. After doing a more in depth search this is not just diesel engines that are effected with timing chain premature wear, also I noted they are mostly BMW & VAG german engines. Interesting in the bmw mini N47 engine it shows the chain tensioner had snapped in half as well as chain has stretched and jump a tooth, and consequently moved the timing by one tooth they were very luck it was caught in time, most certainly a few more miles the engine would have been a wrecked requiring a complete rebuild. https://www.youtube.com/watch?v=l61_q06J4DA

Bonus you are going to get double the heat out of that load of beech wood !

I did just that last year on my F11 with my bmw Foxwell NT510 rewind the calipers back for new rear pads, so I would imagine all latter models of the bmw Foxwell scanners should do the same.

I was told the recon setting on charger is for flooded cell battery and not AGM or Gel batteries, this was the answer I got from customer support CTEK themselves. If you do require a new battery I have had good prices from Tayna, with a quick delivery they do offer from £20 to fit locally if you are unable to fit the battery yourself, worth checking out I used them last year for a Bosch AGM battery with 5 years warranty. https://www.tayna.co.uk/BMW-5_Series-Car-Battery

Whilst it was not the the F10 shown the negative post is in place it is in similar place.
