What to watch for
The list covers the generation, the engines and the transmissions. Once you pick the version, only the faults that apply to it stay.
The 1.0 MPI has a timing belt, not a chain.
Applies to the engine CHYA, CHYB, CHYE.
On short urban trips the particulate filter cannot burn through.
Applies to the engine CUSA, CUSB, CUTA and 1 more.
On AdBlue (SCR) diesels the NOx sensor after the catalyst ages, and the tip of the dosing valve crystallises.
Applies to the engine CUTA.
The injector does not close fully, and with the engine standing fuel drips into the cylinder.
Applies to the engine CHZC.
A thin wall of the mechatronics valve body can crack, which causes a loss of pressure.
Applies to the transmission DQ200.
The internal springs of the flywheel tire, and the two discs knock against each other.
Applies to the engine CUSB, CUTA, CUSA and 1 more.
In the EA211 the water pump and the thermostat are one plastic module, and the pump is driven not by the timing belt but by a separate toothed belt behind the exhaust camshaft.
Applies to the engine CHYA, CHYB, CHZB and 4 more.
The water gets into the cabin through the windscreen drain or the door seal, and collects in the foam under the carpet.
It can affect every car in this generation.
8 more faults belong to this generation. On the version page, only the ones that apply stay.
The manufacturer fixes these for free at a franchised dealer. Ask with the VIN whether it was done. The list covers the whole generation. We did not filter it by model year. Some apply only to a narrower production window.

2014–2018. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.
No. It depends on the engine and the transmission too.
The fault list is.
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.
