Everything. Here in the US there is a voluntary service campaign for this engine. Dealers, on a BMW expense, replace injectors, CCV hoses, timing chains, valve seals and many more. As per BMW service bulletin only AGM battery has to be installed and replaced every 6 months. And many more horror stories.
