There's a plethora of info at the "other" forum thats diesel specific: http://www.e90post.com/forums/forumdisplay.php?f=377

Here's US sources for the tunes:

Yeah so spending ~4000 to have someone fix your emissions, fixes one major problem area on the diesels. But he will still have potential vibration damper failures, glow plugs, glow plug modules, vacuum lines, oil line, boost hoses, engine mounts, MAF failures, etc. there is no bullet proofing the diesel. There is only spending a lot of money to fix weaknesses. I know, I've done the tuning, blocking etc. stuff still breaks. Folks also have occasional transmission failures, turbo failures etc. plus all the other things the break on an x5. My advice is an extended warranty is cheaper than fixing it all yourself if it fails. It's a waste of money if your BMW is reliable. Mine dosent have a cbu issue anymore, but it still greats me with monthly ses lights. But I do enjoy the extra power and fuel economy.

The diesel has been just as unreliable as my n62 x5, and expensive to maintain but I'm very different ways. I seem to have an attraction to unreliable bmws lol. Btw the reliable bmws are the simple basic models, the more complicate and options the more potential for expensive problems.
