Review on 🚘 YCT OCV Oil Control Variable Valve Timing VVT Solenoid: Compatible with BMW 128I 135I 328I 328XI 330CI 335I 335XI 525I 525XI 528I 530I 535I 740I 740LI X3 X5 X6 Z4 - 11367585425 917-241 by Chris Barreto

In my 328i the original solenoids were replaced with these YCT solenoids and the performance and check engine light problems were fixed but only for a few days. About a week later, the performance issues and check engine light returned. In the end the solenoids were replaced with some OEM units and performance issues and the check engine light stayed good for months. Not recommended unless you really want to take the risk as other reviews seem to hit or miss.
