BMW E46 & E39 Most Common Vacuum Leaks P0171 & P0174
The P0171 and P0174 codes will plague every owner of an E46 or E39 BMW at some point in their lives. So, 99 times out of 100 they are caused by a vacuum leak and on the M54/M52 engine there are a few common causes of vacuum leaks. So common that I'd say 95% of cases will be covered by what I go over in this video. I also talk about what a vacuum leak is, how a MAF sensor works, and so on. One thing I don't cover in this video is how to test your oxygen sensors to see if they are working. I will do that in a future video. Please also take a look at these other videos I've published: E46 Common Repair Steps https://youtu.be/Zt3XFkd97dc E46 CCV Replace & Intake Removal (Part 1) - See It Clearly! https://youtu.be/ZDP8Dma0nUs E46 CCV Replace & Intake Removal (Part 2) - Put It Back Together! https://youtu.be/3Mrofw6rRHU Good luck!
