I purchased a 2015 Fiesta 1.5 TDCI in 2019 for £35,000, which has been carefully maintained both before to and during the acquisition. Primarily used for commuting on A roads and highways, under 10,000 miles each year. I believed that a turbocharger typically endures around 150,000 miles; nevertheless, I have reached 72,000 miles, and the technician I consulted has indicated that the wastegate has seized. Is this typical, or does it indicate an underlying issue with the engine that has led to the turbo's failure? Will the component be covered by Ford if the car is under 10 years old, similar to their wetbelt engines, or have I inadvertently purchased a defective vehicle?
The technician has estimated £800 for the replacement of the turbo, oil pipe, and an oil change, indicating a significant price. He asserts that he attempted to release it but was unsuccessful. Do you have any more recommendations? Should I attempt to release the wastegate independently, despite being a total beginner, before spending £800?
