Mercedes-Benz M Class 3.0 ML280 CDI Edition 10 7G-Tronic 5dr 2009 Diesel Automatic 110,000 miles Cat - D v light damage Just passed MOT, a really lovely car, great condition for its age, however Issue with electrics. Taken to diagnostics, they found corrosion on both ECU's, work stopped there, source of water not found. Parasitic battery drain, manual switch added to battery to counter issue. Other than the electric issues, it's a great car, the only warning light is the left side SRS which I've been told isn't a critical issue and still safe to drive.
