I couldn't find either of those codes in Ross-Tech, so I can't offer any suggestions. If you do use VCDS, whatever codes it gives you will be in Ross-Tech, and will give you possible solutions too.
I'll give that a try! Maybe one of my solder connections wasn't as good as I thought, or I crossed a wire while I was working under the car with the soldering iron.Seeing that you have VCDS, you can run an adaptation sequence on the car and during that process it will test each o2 sensor and give the status as a pass or fail.
If I recall correctly, it's somewhere around 70miles. We don't have emissions test requirements here in MI, but it was required in the part of IL where we used to live.If you use this as a tool to determine whether your car will pass emissions or not, make sure you put on the minimum number of miles for the learning process.
Off the top of my head I don't remember what that number is.
Thanks! So far, the codes haven't returned - so they may have been left over from before the repair. But I'll update again after the weekend.DTC 19718 You need to swap the places of the lambda behind the catalytic converter bank 1 with bank 2
