Turbo failure on BMW E90 320d - Should I ask BMW to pay?

BMW Diagnostics has thrown up a Turbo failure on my BMW 320D registered in 2010 - cost to replace £1552. Current mileage is just under 50,000 and I regularly use the car for long trips. Do I accept this repair or should I challenge BMW?

Usually caused by cabonisation of the oil in the turbo bearing oil feed and oil return pipes because the engine is switched off without idling first for 30 seconds after long ascents, after towing, or when stopping for fuel on a motorway. These must be replaced at the same time as the turbo or it could happen again within 1000 miles.
