How much should it cost to change the turbo unit in my 2008 Hyundai i30?

My 2008 Hyundai i30 2.0 has just had its service and MoT at the main dealership (as I always do). During the service the technician noticed one of the pipes was making a noise, however, he couldn't identify which pipe as there are three or four pipes in that area. The service manager said that it's a major problem and the car will lose power when being driven. I took it to my local garage who have investigated and have said that a new turbo unit is required costing, £800, plus fitting. Apparently Hyundai charge £1200 for the unit and they are on back order which suggests it is a common problem.
If the turbo itself has failed it's probably because the oil feed pipe to the turbo bearing and oil return pipe got blocked with carbonised oil from repeatedly switching the engine off when the turbo was too hot. The short supply will be because this is an obsolete engine, replaced in the i30 by the 1.6 CRDi in about 2009. But the turbo might be a standard unit. You can check with that offers an exchange service.
