Frequently asked questions
Which Mercedes Benz A-Class W177 engine is the most reliable?
A180 / A200 / A250 (M282 1.3 / M260 2.0) — Maint. Sensitive verdict. The entry petrols use the 1.3 M282 (A180/A200) — the Mercedes badge on the Renault-Mercedes co-developed 1.3, physically the same engine that wears Renault's '1.3 TCe' name in the Mégane/Kadjar/Captur — while the A250 steps up to the Mercedes 2.0 M260. The 1.3 is willing and economical with the modern direct-injection-turbo cautions: intake-valve carbon over time, turbo/PCV care, and coated bores (any wear is a specialist job); the M260 2.0 is stronger. Both pair with the 7G-DCT dual-clutch (check it for shudder/fluid). A serviced car is dependable. Buy on oil and DCT history.
