Well maybe start there then. Then you would know that there were several witnesses (he didn't do it in an office in secret, but in the entrance lobby).
You would also know that the incident happened a while ago and the parliamentary review board has already stripped him of his immunity for this case. So a group of his colleagues already determined there is sufficient evidence for such an investigation.
If it’s so easy to slander and cause legal woes, as to say “they did a Nazi salute,
This is true of any crime. Unless you have more than somebody's word to go on, there won't be any kind of investigation. Moreover, as an MP the guy enjoys parliamentary immunity unless it is specifically lifted by a committee of his colleagues (which includes members of his own party).
would you still think these circumstances are fine if the claim of the salute were false
Yes. If an MP is accused of any crime, this is the normal process of investigation. Wether or not the accusation is true or not is precisely the point of this investigation.
political party member were arrested because someone disagreed with their ideology
Not just a party member, an MP specifically. And they were not arrested, just formally charged with a crime. And it wasn't over an agreement of ideology, but for doing a very specific thing that is well known to be illegal (with exceptions for education and art). Now, if your ideology can not be expressed without doing a Nazi salute, then I guess, yes your ideology is illegal in Germany. Wether or not that is good or not, is left as an exercise for the reader.
What if it were a left leaning party member who received the allegation?
Presumably the same thing would happen except any non-AfD party would immediately conduct their own internal investigation and promptly boot any member that actually did this.
