Out in wife's X5 today and had tyre pressure warning light come up.  After a couple of miles [at <50 mph] was able to pull into services.  3 tyres at 1.9 Bar and one at 1.3 Bar.  All now at the correct 2.2 Bar but spoke to tyre shop who will inspect and repair if safe to do so tomorrow (read: you are fooked and will need a new 370 quid tyre despite it only having done 8k miles haha)

Quel bummer

Why, do you have a slow puncture or could it be nothing more than not keeping on top of the pressures?  If you do have a slow puncture, why not put some tyre magic it to the affected tyre and the puncture will be fixed.

RFT is the issue mate. They will check for valve damage etc but I somehow think I will come out of there with a new one on. Still I am not taking chances where the kids are concerned.

That's my experience too. Although run flats can be repaired now, if the puncture is on the edge they won't do it. Just like a normal tyre. My last two RFT punctures have been on the edge of the tread

Outcome was as expected, a nice new 357 quid rear tyre!
They would not repair, despite nail not being on sidewall. 
These guys have known me for years and do major galvanised repairs when normal mushroom plug methods are not enough. Obviously 300 quid is 300 quid to a business, but there is so much divergence of opinion on runflats - basically nobody wants to accept liability for a repair on a RFT which has been driven 'unknown' miles.  I am not taking chances where my kids are concerned; plus RFTs are more convenient for wifey to have.

Not sure what you mean by valve damage snipez.  Whether run flat or not, having tyre magic will not affect the performance of the tyre in a negative way.  Tyre magic and the likes only repair holes up to a few mm wide, so nothing more than a convenient way of repairing small punctures instantly, so no miles used on the run flat without air.

I would never do anything I believe would put my family at risk, and wouldn't use these products if I felt they were dangerous.

I had re-inflated tyre so sidewall damage (which is the issue with RFTs) could already have been done.  TPI went off when it was 50% pressure versus the others, so not very good at letting you know when you can still do something cheap about it! I was not in the mood for hoiking the car up on the jack, removing a wheel and inspecting/removing offending nail plus adding tyre magic and hoping it would all be OK.  One of the problems with having RFTs I guess.  I will look into what I can do for my own car though - just not taking any risks at all with the wife's
