Replacing Timing Chain on BMW E90

Model: BMW Serie 3 E91, E90, E92 - Years 2005-2013
Part: Timing belt

Let's see how to change the timing chain on your BMW E90 N46. It may seem a bit complex at first, but you just need to remove a few screws to access the timing chain. First, disconnect the injectors; remove the depressor to which the injectors are connected, and then remove all the screws located on the cylinder head cover. This will allow you to take off the cover and finally access the chain. Disconnect the connectors located on the engine cover side; then loosen the two pulleys to remove them along with the timing chain.
