We here at EclipseCarTuner are more than happy to help a DSMer in need; however to ensure that you get good advise from the staff or fellow ECT members please include the following before the question. Once again thank-you for your support.

1) What is the Year, Make, Model, Style(TSI GST GSX RS GS etc.)
2)Have you done an engine swap(ie 7bolt changed to 6bolt).
3)What mods have been done to your car. Include everything down to the gauges(since gauges have to hook-up to the motor and accesories there are chances of something breaking on them or not being hooked up right and that causing a problem).
4)If it is a noise with the Engine try to figure out about where on the engine it is coming from and state what you found.
5)If your car is smoking, include how much smoke, when the most smoke appears, what the color of the smoke is.
6)How often does the problem happen(under hard throttle, soft throttle, idle, in gear, out of gear, etc.)
7) if you did something and the problem started immediatly after.

What you have already looked at or changed trying to fix it.
