BMW 335i N54 engine failure in performance

My BMW 335i was the stronger acceleration always in the emergency (engine failure in performance).
I thought I try first as the best and see ... it helped !!!! I filled a bottle of liquid Moli added to a tankful. The next test for the gas station exit not helped. Probably because the product had not yet arrived in the engine;) ... But a few kilometers later, the big surprise !!! BMW drives and accelerates back to normal without to complain about! I can speed through the whole speed range !!!! I suspect that it was because of coked injectors or solenoid valves!
You do not know if this is a long-term solution has yet but first helped me !!! So 5 stars for this product !!!!
