Hi forum
I test drove a 93 auto TT MKiv today (GZ model). Generally I was happy with the condition and performance except for a white smoke issue. It was a cold day, but the engine had been run before earlier so was warm. No smoke immediately after starting, but a trail was visible after less than a minute. Still there after a few minutes of running. Then we did a bit of blipping and revving. Smoke increased a bit with revs, but still what I'd call a trail, never as much as a cloud. During the test drive (which included some hard acceleration and high speed) the smoke appeared to have stopped (as far as I could see from looking in the rear view mirror - unfortunately I didn't have anyone available to follow us and watch) but it's difficult to tell when the car is moving. After returning from the test drive, the exhaust was smoke-free (although it smelled quite noticeably) for two or three minutes, then the smoke returned as it had been before the drive.
For the last four or five months this car has been driven very little (although started and run - probably just briefly - quite often) so has mainly just been parked in the same place. There was no hint of a problem starting at any point today.
I have seen there are quite a number of "white smoke" threads on this forum and I'm looking through them, and I am aware that nobody is going to be able to give a firm and thorough diagnosis over the internet, but I wonder if anyone out there is aware of any reason why this smoke issue might be linked to the car being largely unused for a few months such that simply driving it regularly might be part of the solution.
Many thanks in advance
Gavin Deane
