The problem here is that they've driven it little and CRA will assume that a fault that presents itself in the first 6 months after the sale was there UNLESS the dealer can prove that it wasn't.
ACE Engineers or DEKRA can provide an independent engineer's report but that may well say that the "chain snapped due to age-related wear and sudden breakage in the plastic chain guides which would've been present and developed at the point of sale"...
BMW will not offer a contribution at over 100K miles unless the car is only a few years old. You can always offer to chase BMW for it but that's unlikely to be enough to make the customer happy.
££££ is what everyone wants.
You were already open when you supplied a 100K mile BMW (I sell them well too) but I would agree that you shouldn't rush into getting it back. If it arrives back to you, you will end up owning it.
A good option if it comes to that (and if you have the stock of course) is to offer the customer another one of your cars in swap, one with lower value but similar size and condition.
i had same experience with bmw 1 series and 3 series 2005 onwards when i use to sell loads of bmw.
common problem timing chain jump due to low quality of plastic tensioner which runs timing chain.
Try to contact bmw specialist in your area or i will suggest one bmw specialist http://www.rawspares.co.uk speak to Robert or Charlie on 0208 684 9353 they will help you to fix the problem if engine not damage, make sure don't try to start the vehicle. Cost approx £500 or more subject to check the engine properly. better pay them and get it fixed instead of taking the car back. try your luck to get some money from customer towards the repairs. thanks

Translated, you won't get a fucked battery to take a full charge.
Battery is wanked, change it, replacement AGMs can be had from around £130 up depending on size.
