Buying BMW X5 3.0d Sport (Auto) 2002 - what should I know?

[trumpetdropper]

Hi Fellow Piston Heads

I have been the owner of an E39 523iSE Touring for the last 8 years and looking for a change.

Due to a leg injury (bike accident)which won't get any better - I now have difficulty getting in/out of standard cars and something taller will make things easier.

Currently my sights are fixed on the X5 3.0d, as it offers similar space and features to 5 series as well as similar fuel economy - but how do I spot a bad one?
I've heard the turbos on the diesels and auto boxes can be trouble - what do I look for?

Any information welcome (Pros and cons)

Cheers
