Dear All,
the exhaust emission warning lamp (yellow, engine shape) has been coming on intermittently (not blinking) and now stays on permernently.The guide book says its a lambda probe fault or o2 sensor, when I took the passat into a garage they said it could be a lot of things and not predominently the probe, they then said that they reset the computer, this cured it for a while but now the light has come back on, any ideas or is it mainly the probe that causes this light to come on,
cheers hod.
