What are some of the 2011 bmw 535i twin turbo problems?

The most common issues with the 2011 BMW 535i have nothing to do with the vehicle's twin turbo apparatus, so that's the good news. Turbo repairs and replacements can be some of the most expensive on the vehicle, so You should rest easy knowing that BMW's are some of the best and most durable. However, it's not uncommon to get a small oil leak from one or more of the gaskets or attached hoses. The good news is that an oil leak will very rarely necessitate replacement, if it's caught early enough. The relevant gaskets and hoses can be repaired and/or replaced, and the turbochargers themselves will be just fine. However, catching these problems early is necessary, which means that You should keep a watchful eye under Your hood, and take action if You see any oil where it shouldn't be.
