Hello all,
I need some help troubleshooting & figuring out the part numbers for my o2 sensors that need replaced. I've done some searching but but found conflicting info. I'm running the DS1 stage 2 ots tune and the check engine light came on driving home from the tail of the dragon.
Here are the errors from the vag-com
