Hi I have a P2181 code on my 2008 VW GTI 2.0 FSI I'm in a Chicago area so is cold up here in the winter, I do have heat after the engine is been running for a few minutes and the temperature gauge on my dashboard acts pretty normal which makes me think that my problem is within the sensor sending the wrong info to the computer am I wrong to make that assumption tho? Also my scanner say P2181 Cooling system performance ( 008 Implausible signal ) thanks so much!
