Most expensive repairs: the engine faults that cost the most to fix

The most expensive documented repairs among the the 175 engines and gearboxes we have analysed reach €10,000: “Valve body and mechatronic failure: erratic shifts or a locked-up gearbox” (ZF 6HP, at the dealer) and “Excessive oil consumption and engine failure” (1.2 TCe, at the dealer).^{[1][2][3][4][5][6][7][8][9]}

Faults ordered by the highest documented figure for each, whether from an independent garage or a dealer. Prices are for Spain, including VAT; what each figure includes is detailed on the fault's page. It covers only the engines we have analysed. How we calculate costs
