Whoever you'd want to claim from, even if you had a current inclusive warranty, would be examining the engine and the turbo and its piping would be dismantled for close inspection...plus the service history would be checked closely, before any warranty goodwill forthcoming.

This would include full engine oil analysis if there were any suspicions of low/wrong/contaminated oil.

They'd want to know why it failed, and only then would a decision be made on whether warranty would be applicable, if you the owner/driver were at fault then obviously no warranty would apply.

I'm not sure how much info the car's computer would hold on a car like this, in lorry world it's quite shocking just how much information the vehicle not only holds, but on mine it sends live feed back to the maker who in turn sends all relevant driving issues to the operator (my boss), how far cars are down this monitoring road i wouldn't know, but if it isn't already in place i have no doubt it's coming shortly.

Ok, just thought as there was a known fault with the engine that might help my case. Someone I know in the motor trade thinks I might be able to claim on my motor insurance but I’m not so sure. Anyone any experience of doing this? I’m with. Aviva

Car insurance is to cover fire, theft and damage from accidents.

Claiming for mechanical failures from your insurer will provoke helpless laughter in their office, though their response to you may be more diplomatic.
