Hi!
Please review turn:lanes=slight_left;through|slight_right|slight_right;reverse
on way
way/481455523#map=14/24.8069/67.0669
It seems you have combined two ways with different turn:lanes values here so that the result is invalid.
Please be very careful when combining ways, there is normally a good reason why they are separated.

Good question. I think whenever you use a tag value for the first time you should try to find a wiki page for it and check taginfo.
So, in this case you might as well use highway=abandoned + abandoned=path
if you like this better.

Hi!
Please review typo oneway=70 on
way/437669283

Hi! Please review typo oneway=RD4
No idea what you meant with this.

Hi!
Please review typo oneway=yes + oneway:bicycle=no+cycleway=opposite
I assume these should be 3 tags,
but cycleway=opposite
doesn't match the changeset comment "bicycles allowed in both directions"

Hi!
Please review typo oneway=Buckner Ridge
on way/521289895

Hi!
Please review typo oneway=surface on
way/26401507

Moin!
Was bedeutet denn oneway=bollard an
den nord-östlichen Stücken der Wilhelm-Hoegner-Straße ? Tippfehler ?

Hi!
Please review way way/409080024
Isn't this a junction=roundabout which would be highway=primary and oneway=yes ?
Current Bing pictures show the roads at very different posotions now.

Hi!
Please review typo oneway=on
http://overpass-turbo.eu/s/rv9
Not sure if you meant no or if "on" stands for yes.

Hi!
Please review typo oneway=parking
on these service roads.

Hi!

Hi!
Please review typo oneway=roundabout on
way/148810005

Hi!
Please review:
What was meant with oneway=both ?
Maybe sidewalk=both ? Or is it simply not a oneway at all?
See http://overpass-turbo.eu/s/rv5

thanks!

Hi!
Please check typo highway=agricultural
on 4 ways in this changeset.
Did you mean track or dd you want to map access?

Hi!
Please review typo footway=paved on way/494732227
I assume you meant surface=paved?
Looks strange as other roads in this area are not paved.

Hi!
I've noticed a lot of nodes here which are not tagged and not connected to any way.
See area around this :
node/4736342115
Seems you have accidentially deleted the building ways before uploading the data.

Hi and welcome to OSM!
I've noticed a few ways with highway=services which don't look lite services areas, so I assume you meant highway=service.
http://overpass-turbo.eu/s/ruG
Some of them look more like highway=path or track.
See also osm.wiki/DE:Tag:highway%3Dservices
I've also noticed some waterway=river
which look more like waterway=drain
See here:
way/507847610
See waterway=*
Hope this helps?

Hi!
Please review typo highway=services on several roads here:
http://overpass-turbo.eu/s/ruF
They seem to be highway=track, not service
