Open your hood, the black emission sticker had valve lash.

.10 intake, .35 exhaust I think.

Make sure to let it sit over night before doing the adjustments. They're different if the water temp is above a certain number. Those are the cold numbers, the ones you want.

For 240D's it's .10 and .30. That's slightly different than the 300D. Manual says to set it .06 more for extremely cold temps.
