Hi folks I have a 95 tt w58,after a top speed run on the local runway,my engine check light came on but went off about 10 seconds after,and the car just doesn't seem to be running right since,I have my full power but the car sounds somewhat strange on idle,when I start the car is seems like it's starting quicker than normal also and sounds like there's a slight rattle coming from the exhaust I've also noticed it's a bit smokey when I rev it not a major excess of smoke but it is noticeable? Could my j-spec turbos be on there way out? What I've never noticed before is slight oil deposits on my air intake pipe coming from my ssqv? Can anyone shed me some light..my oil pressure and water temp is all perfect also
