Audi A8 W12 Engine Overhaul: 110,000km Maintenance

This flagship Audi A8 W12 originally cost over 2 million Yuan, but with only 110,000 km, it was burning excessive engine oil every 200 km. After being quoted a staggering 700,000 Yuan for a full engine replacement at a 4S shop, the owner brought it to me. We performed a complete top-to-bottom overhaul for under 70,000 Yuan, restoring this legendary W12 power plant to its former glory. Watch the full process of disassembly, cleaning, and precision reassembly.
