in the meantime i thought that genuine parts might be with better quality than the producer (OE ones)

The Best of Mercedes & AMG
When looking to replace a part, I consider the price and criticality of the component. For things that are difficult to replace, such as engine mounts, the extra dollars are worth the expense of replacing a prematurely failed part. For others things, like the oil filter, the price difference does not justify the risk of using a non-Genuine part, since they are the same. Then, there is always the decision to pay 2 to 3 times the price for an expensive part just to use Genuine. For example, the HPFP for my SL400 is pretty easy to get to because of all the space in the engine bay. So, I will go with the Bosch OE pump for ⅓ the price of the Mercedes Genuine pump.
