Sure, there are differences in pronunciation, grammar and syntax between Berliner Schnauze and Hochdeutsch, or High German (the standard German spoken throughout the country). For example, the Berliner Schnauze uses a "j" where High German uses a "g". So gut (good) becomes jut. But most don't think about grammar and syntax when it comes to Berliner Schnauze. It's an attitude that's entirely based on a situation.
