Cambio sensores, inyectores, catalizador... El final del BMW Z4

After three years of trying to solve the idling problem on my 2005 150hp BMW Z4 2.0, I've decided to put an end to this project. 🧰 In this video, I show you everything I've done to try to fix it: replacing sensors, inspecting the intake system, vacuum leak testing, replacing injectors, installing a new catalytic converter after the exhaust gas failure at the MOT... and much more. 😓 It's been months of testing, parts, visits to garages (including the official BMW garage), and a huge investment of time and money. In the end, the exhaust gas problem has been resolved, but the idling problem remains. Honestly, I no longer see it as a problem worth continuing to invest money and energy in (when I have other cars and motorcycles in line), so I'll sell it as is, which runs perfectly, except that the idle speed isn't stable when stopped. 🔧 It's not the ending I wanted for this car, but it is the most realistic. Still, I hope this video helps you understand what lies behind these types of persistent failures, and how sometimes, even when you do everything right, things don't turn out the way you expect.
