Then I switched to nitrogen and haven't had any problems since.
How often are your tires losing air? Is it just the one or multiple?

Well I just filled them up but I got a message that the front right tire was 40 then a day later was 37 just refilled it so we will see what happens. Can an MB dealer put nitrogen in your tires ?

You can have 5-7 psi differences at these pressures with cold/warm(driven) tires. I used to measure in the AM after it sat all night. IDK about nitrogen, I get why folks use it, but air is already about 80% nitrogen anyhow. Does that last 20% make a big diff? Maybe for race teams, IDK.

A loss of one lb over 7-10 days is a leak to me. The leak is relative to your other tires, of course. The only time I check that I consider reliable and repeatable is in the morning, in the garage.

I check my tires in the morning as well. Compressed air will fluctuate more than nitrogen due to water condensation.
It's normal for your tires to lose few lbs after few months of driving. For example, all my tires lost about 5 lbs during the summer driving (5-6 months)... I just refilled them back to 38 psi (I have aftermarket wheels & non-runflat tires).
My conclusion is as long as all your wheels are loosing air at the same rate, you do not have a leak... just fill them up as needed. but if 1 wheel lose air faster than the other 3, then have them check for bead leaks or nails in tire.
