Dacia Duster 2

Blue dCi variant of the K9K with AdBlue injection (SCR) for Euro 6 — still a very robust engine. In addition to the regular service schedule, top up AdBlue and keep an eye on the SCR catalyst. Injectors and high-pressure pump remain the typical wear points at high mileages.

• !! Injectors worn out from 105,000 km

  Delphi injection system (pre-2006) is particularly troublesome — injectors worn out by 60,000 km. Siemens system (from 2006) is significantly better.

Renault's 1.2-litre turbo engine is notorious for excessive oil consumption and timing chain problems. Excessively wide piston tolerances lead to oil burning that thermally damages the exhaust valves and can ultimately result in total engine failure. Check oil level at least every 2,000 km; inspect thoroughly before purchase.
