What happens
Symptom. A screen that freezes or reboots, Bluetooth and audio dropping out, and occasional warning lights that clear on a restart.
Cause. The pre-facelift infotainment is the weak point and its module and software are where the faults concentrate. A weak battery makes all of it worse, since low voltage upsets several modules at once.
How to check it
On the drive
Work the infotainment for several minutes on a test drive, pair a phone, and check whether the battery has been replaced. Facelift cars from 2014 are much better here.
Include low-speed manoeuvring, not just an open road.

| Variant | Chassis | Body | Years | Risk | Good buy | Cost as % of good buy |
|---|---|---|---|---|---|---|
| 1.6 TDCi T1DA | Mk3 | hatchback | 2011–2018 | R3 | €2,300 | 18% |
| 1.6 TDCi T1DA | Mk3 Estate | wagon | 2011–2018 | R3 | €2,450 | 17% |
| 1.0 EcoBoost M1DA | Mk3 | hatchback | 2012–2018 | R3 | €2,500 | 17% |
| 1.0 EcoBoost M1DA | Mk3 Estate | wagon | 2012–2018 | R3 | €2,650 | 16% |
The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
