Multitronic vs ZF 8HP: which gearbox is more reliable?

According to our risk index, the ZF 8HP gearbox carries less risk than the Multitronic gearbox: 36/100 (moderate risk) versus 64/100 (high risk). The Multitronic gearbox has 2 documented serious faults, the main one being «Wear of the variator chain and cones»; the ZF 8HP gearbox has 1 documented serious fault, the main one being «Mechatronic failure as the gearbox ages (sometimes with reverse)».

Is the Multitronic gearbox reliable?

The multitronic is the continuously variable (CVT) automatic gearbox that Audi fitted, with front-wheel drive only, between 1999 and 2014: first the 01J code and, from 2007, the 0AW. It was fitted to the A4 from the B6, the A6 and the A5. Its reliability is limited - Gebrauchtwagenberater calls it Audi's "black sheep": the 01J concentrates control unit failures, jerking when pulling away and chain wear; the 0AW is notably more reliable, although it does not eliminate them entirely.[1][2][3]

Is the ZF 8HP gearbox reliable?

The ZF 8HP is an 8-speed torque-converter automatic gearbox, launched in 2008 in the BMW 7 Series and later adopted by BMW, Audi ('tiptronic'), Jaguar, Land Rover, Alfa Romeo and Jeep. It has a reputation for being reliable, although it accumulates jerking that sometimes calls for reprogramming the control unit, occasional mechatronic failures and leaks from the sump gaskets; the oil is sold as 'lifetime', but several garages advise changing it earlier.[4][5][6][7][8]
