2nd generation (2014-2017) gearbox: faults and reliability
ZF 8HP (caja automática de convertidor de par, 8 velocidades) version
Buy
It is the most widespread version and the one with the most known mileage: in the analyses of several models (BMW X3, BMW X5, Audi A6) gearbox faults are a minority of the total accounts, although occasional jerking is still documented and, less often, mechatronic faults or leaks. It is worth checking the history, but there is no systemic defect that argues against buying.[1][2][3]
What changes in this version
Generation with which the gearbox reaches Jaguar, Land Rover, Alfa Romeo (Giulia) and Jeep (Grand Cherokee, as the 845RE under Chrysler licence), while BMW and Audi were already using it across the board. It adds torque variants and software adjustments without changing the gearbox's basic architecture.[4][5][6]
Engine codes of this version: 8HP50, 8HP70, 8HP75, 845RE.
Faults of the 8HP50 gearbox
The documented engine faults that affect this version and its years, from most to least important.
- 1High severityFrequency: OccasionalElectronicsMechatronic failure as the gearbox ages (sometimes with reverse)Yes, although in a minority of cases: there are documented ZF 8HP mechatronic failures on BMW after 120,000-130,000 km, costing €1,400 to €3,500, and also control unit or electronic selector faults on Audi and Land Rover.Repair: €1,400–€3,500
- 2Medium severityFrequency: CommonTransmissionJerking and hesitation when changing gear, sometimes needing reprogrammingYes: on BMW, Audi, Jaguar and Alfa Romeo there are accounts of jerking, hesitation or harsh shifts with the ZF 8HP. It is usually due to ageing oil or the calibration of the mechatronics, and the dealer often fixes it -not always first time- by reprogramming the gearbox control unit.
- 3Medium severityFrequency: OccasionalLubricationOil leaks from the gearbox gaskets or sumpYes: on the BMW 1 Series and the Jaguar F-Pace there are accounts of oil leaks from the ZF 8HP gearbox gaskets, in one case already at 40,000 km. If it is not repaired soon, the loss of pressure can speed up internal wear and lead to the jerking or mechatronic failure of the related faults.Repair (garage): €1,000–€2,000
