E53 X5 Engines

[tsinc]

I'm on the lookout for a tow car for my track car and I think an E53 X5 suits the requirements well.

I've been looking at V8's as for the mileage I do I'd rather have something a bit more powerful than the standard 3L diesel.

Are there any glaring / known issues with either of these engines and the associated differences that come with the models they are in?

I'm only looking for one under 70k miles with full service history but I've read a few things about the air suspension on the 4.8's and the sunroof on all models being problematic.

Thanks!

I have heard of some timing chain problems on the V8s, probably due to infrequent oil changes and weak tensioner.

Would timing chain tensioner be classed as a serviceable item or covered under BMW warranty if any issues occured? I had a quick look at the BMW warranty and it looks like it would be around £90 per month for a 60k mile X5.

You'd have to check the policy terms, afraid I'm not familiar with them.
