LOL! Lito, you'll be up on your chatspeak in no time!
Anyway, Lito asked me about this, so I thought I'd post it. If you have your cluster coded for the service interval and a service interval alert comes up on your cluster, you can reset it without using VAG-COM. Here's how:
Put the key in the OFF position. Push and hold the tripmeter button (the one on the right by the speedometer). While holding the button, turn the key to the ON position, but don't start the car. The display will say "service" (stock) or "SERVICE NOW" (MFI) depending on your cluster. Release the tripmeter button. Then turn the clock button (on the left by the tach) to the right one click. This will reset whatever service interval has been displayed, and your display will then go back to normal. Switch off the ignition. Note that if you want to change the values of the interval, such as mileage or time, you must do this with VAG-COM.
Incidentally, in case you didn't read the ross-tech page, channel 45 adaption is for oil quality. If you have an oil sensor, enter 4 for diesel, 2 for gas, and 1 if you would rather use time- or distance-dependent service intervals rather than the flexible service interval.
