TUBI ??
I have done 600 miles in my tt cab with a new tubi exhaust, when driving yesterday the engine warning light came on and a message to take the car to the OPC, when they conected it up to there computer they told me it was a warning about the cats on the exhaust, they say that with changing the exhaust the management system can possibly reconise a fault as different to stock,has this happened to anyone else, they reset the management system but said it could happen again,
