My wife's 2006 Beetle 1.9TDI had a warning light come on. She had her emissions checked Friday and that's when the light came on. Looking in the owners manual showed the yellow/orange engine light as exhaust trouble. After having it analyzed today it came back with a P0128 code indicating a faulty CTS. I'm very confused now. What does one have to do with the other? Should I start cheap and replace the CTS first and see if that solves the problem? I don't have $200 for the dealer to put it on his analyzer and then stick me for parts too.
The car has had no issues at all prior to Friday and her emissions check was very GTG as expected.
