I did a fault code check Torque Pro and it said there were no stored codes in the ECU. Maybe I should try to get the light to turn on then check for codes again.
Could certainly be a possibility since the cold wet weather has arrived here in the Pacific Northwest. I'm planning on replacing the tires very soon. These ones were on the car when I bought it, even though they are fairly new, I haven't been impressed with them. I can easily spin the tires any time I start from a stop.
Usually, the DSC light will come on and stay on if you have an overboost condition or if your TMAP sensor is flaking out. How high does your boost get at redline?
I had that happen to me but i also threw codes which made trouble shooting easier... (ending up being one of the map sensors, don't remember which one). Replaced the sensor and everything was back to normal. Does it idle okay? Mine starting stalling at idle after a day (took a while to get the part)
I think of seen around 16-16.5 psi at boost at other times when I have been monitoring it. I don't know what I was getting when the light came on. Idle, for the most part, seems fine, no stalling issues. I'll look into the TMAP sensor, it may be good to replace it just in case.
Make sure to get an OEM or equivalent. I got one from a local parts house and it lasted all of 6 months before it died. Replaced with OEM and all is good.
