Hi we have this golf in with us. Customer complaining of rough running from cold and no power, once it warms up it is perfect all day until the following morning then it plays up again.we have plugged scanners in and only code we get is p0121 throttle position sensor.not sure why this would only upset running when cold or are we missing something.is there any sort of temperature sensor built into throttle unit? any help would be grateful.
