The fault
How you spot it
The 7 speed dual clutch of the transverse MFA platform (7G-DCT / 724.0: A/B/CLA/GLA/GLB) started its early years with jerking and firmware faults; today most of the complaints trace back to the mechatronics unit (valve body and solenoids) and the electric oil pump.
Driven with a faulty mechatronics unit, the wet dual clutch wears faster. The mechanical part (synchros, differential bearing) tends to appear at high mileage.
This is not the longitudinal 7G-Tronic (722.9): a different casing and a different fault pattern.

How we know
Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
