You know what tool I didn't think I would need for this job? A drill. Here's what happened when I did a fuel filter replacement on my 2012 MK6 VW GTI.

P2187 - System too lean at idle speed. This common code popped up for me, but it turned out to be a much simpler fix than I thought it would be. Let me know if this video helps you by hitting those LIKE and SUBSCRIBE buttons! At first I checked the common culprits like the PCV valve and the Mass Airflow Sensor, but it turned out to be something different. Post any questions you may have in the comments and I will do my best to answer them! The P2187 code indicates that there's an issue with the air-fuel mixture ratio.

This video is part 2 of 2 of my process for replacing the serpentine belt tensioner on my MK6 VW GTI. Part 1 started with the removal of the old tensioner. This video Part 2 seamlessly picks up where I left off with the installation of the new tensioner.

I had the P0036 and P0037 trouble codes for a little while. Did some research and figured out that the rear o2 sensor most likely had to be replaced. So I replaced it and as of today (roughly 3 weeks later) those codes have not returned. Hope this video helps you out if you're in the same boat as I was! For reference, my GTI is a 2012 MK6 with the CCTA engine. What the CCTA basically means for this job is that my engine only has two o2 sensors, one on the downpipe and one after the catalytic converter. Both the P0036 and P0037 trouble codes had to do with the heater circuit on the rear sensor specifically. There was nothing mentioned about the front sensor, so that's why I only replaced the rear sensor.
