New car E90 323i Year 2011 Mileage 5xk My car engine having noticeable engine oils sludge building up. I was servicing my car by autobavaria according what did bmw scheduled . This is very disappointed and frustrated when they offer me for a new engine change for rm 19k!! Its sound not a reasonable price. The warranty just pass around 10 days when i sent my car for inspection by autobavaria. I know im not the first person getting this issue, anyone experienced can share the complaint route or even a lawsuit case settlement?
