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 EGR cooler cools the recirculated exhaust gas before it enters the intake again, and coolant flows through it while it does so.
Applies to the engine CUNA, CUPA.
Repair: 600–1,500 EUR
On these engines the oil pump is driven by its own small toothed belt, and that belt runs in the hot engine oil.
Applies to the engine CUNA, CUPA.
Repair: 200–600 EUR
On short urban trips the particulate filter cannot burn through.
Applies to the engine CKFC, CLHB, CRMB and 4 more.
On AdBlue (SCR) diesels the NOx sensor after the catalyst ages, and the tip of the dosing valve crystallises.
Applies to the engine CLHB, DDYA.
The solenoids of the mechatronics unit wear out: slow or harsh shifting, then limp mode.
Applies to the transmission DQ250.
The injector does not close fully, and with the engine standing fuel drips into the cylinder.
Applies to the engine CHZD.
The tension of the piston rings is too low, so oil gets into the combustion chamber.
Applies to the engine DLBA.
A thin wall of the mechatronics valve body can crack, which causes a loss of pressure.
Applies to the transmission DQ200.
15 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.

Common questions
2017–2020. 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.
