Reliability, common problems and owner reviews for the Skoda Roomster 1.9 TDI (BSW) / 1.6 TDI (CAYB). Check this before you buy used.
The Roomster diesels span the tough old 1.9 TDI PD (BSW/BLS — the legendary high-mileage VAG diesel, with the usual PD cam/follower-on-correct-oil and DMF cautions, plus DPF on BLS) and the later 1.6 TDI common-rail (CAYB, EA189 — frugal and refined, with DPF/EGR and injector/coolant-pump items). Both are economical and high-mileage capable; the 1.9 PD is the simpler tough unit, the 1.6 CR the cleaner-running one. Buy on oil and DPF history.
