Morning, new to the group today. I ve got a 21 plate (reg May 2021) A220d automatic which I bought from a MB dealership, I’ve a service plan with MB and it’s done under 28500 miles. Engine started knocking and the dual mass flywheel has broken, it’s currently being repaired and will cost £4650 to fix. Everywhere I look says these should last much longer, generally quotes 100000 but many say life of engine. We ve friends who have their own garages and they’ve been really surprised that this has happened. Wondered what thoughts other members have please?
