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 7DCT gearbox reliable?

The 7DCT is the 7-speed dry dual-clutch gearbox that Hyundai and Kia have fitted to their compacts and SUVs since 2015. Several sources based on owner accounts name it as one of their most-cited weak points: jerking and hesitation at low speed, premature clutch wear and, in a minority of cases, early total failures, especially with the 1.7 CRDi diesel.[4][5][6][7]
