How To | Replace N55 VANOS Solenoids | BMW 535i F10

Save TONS of money by doing this job yourself! In this video I walk through the process of replacing VANOS solenoids on an N55 engine step by step. Start to finish this job will take approximately 1.5 hours for a beginner, less if you&familiar with the N55 engine or general auto mechanics. VANOS, short for "VAriable NOckenwellenSteuerung" (German), is BMW&variable valve timing system. VANOS is a variator system that varies the timing of the valves by moving the position of the camshafts in relation to the drive gear. The VANOS solenoids on N55 engines are more prone to failure at high mileage than in previous models, and may require replacement after 100K miles. In my case, I was starting to notice a rough idle when stopped (no codes, new spark plugs/coils) and sluggish/jerky acceleration at low speeds. I had already replaced the LPFP and HPFP, so those were both eliminated. Since the process is the same for cleaning, I opted to replace with new units.
