What is covered

Three months from invoice on used engines, gearboxes and cylinder heads. Twelve months on brand-new, factory-sealed units. Cover is for internal mechanical failure: block, crank, bearings, gears, shafts and valve seats.

What is excluded

Ancillaries, sensors, injectors and turbos, and any unit not fitted by a qualified workshop with an invoice to prove it.

Returns

Seven days on an unopened, unfitted part. Once a unit has been opened or fitted, the warranty terms apply instead of a return.
