Just had the TB and the AIT sensor off to clean them as i've been experiencing poor idleing when the car is cold. Got it all back together and tried to do a TB realignment but VCDS just says "Error" in the far right box! Now I know this was working because I realigned it last week without an issue. I know I've plugged the sensor back in properly because if I disconnect it all my values in VCDS drop to "0". Has anyone got any ideas, do you think its safe to try and start the car?
