I've just got a downpipe and decat for my 1.8t sport AUM, getting the rest of the exhaust at the end of the month. I've heard that there is a secong sensor after the cat. Will this cause me any problems running the decat? I'm going to have it remapped shortly and have heard this removes the use of the second sensor. Is this true? has anyone else done this?
Thanks in advance
