Just out of interest and slightly off-topic but what's the thinking behind replacing the two turbos as preventative maintenance? Are they common failure points with catastrophic consequence? And what, if any, are signs of imminent failure?

I'd also be interested to know what kind of cost is involved in buying replacement units and getting them fitted. Mine (singular, as D3) has lasted 250k but it's on my mind as probably being on borrowed time.

Thanks
