For those who got into the same situation as me, namely received a ban on registration of actions with a vehicle.

Before selling the car, the buyer checked the restrictions on the body number here http://www.gibdd.ru/check/auto/ and it turned out that on August 23, 2016, the bailiffs imposed a ban on registration actions with the vehicle. It is unclear why, to whom (this is important), and what kind of district or regional bailiffs they are (they have different databases).

Out of ignorance and in shock from a recent visit to the traffic police MREO, I registered on the government services portal https://www.gosuslugi.ru/ to get an appointment without a queue. To do this, it was necessary to confirm your identity at the nearest point https://esia.gosuslugi.ru/public/ra/ and actually receive the coveted pin code for presentation to the MREO.
I showed up at Borodin, I was about to take a ticket, but the consultant at the counter told me to go directly to the Chief Inspector at window 8. Where I was informed that they do not deal with bans, they are done by bailiffs (FSSP) and you go to these 4 letters and deal with them. In response to my request to tell me the number of the enforcement proceedings, they were sent to the same place.
But I was preparing, and I found out in advance who these FSSPs are, where their district department is and where the main office is. They have a website where you can search for enforcement proceedings by name http://fssprus.ru/iss/ip, which I did, naturally I did not find any proceedings against myself, they told me the same thing over the phone when I got through to them. Arriving at the Kirov department of the FSSP (Nemirovicha 100/1), I ended up in office 117, where I was sent to office 102, where I waited in line to get an appointment. There they told me the same thing and said that they couldn’t issue any certificates and couldn’t lift the ban, because... Perhaps the regional FSSP did this and they do not have access to their database. In general, in order to do this, you need to obtain a “vehicle registration card” from the MREO.
I go to the MREO on Borodino and get this card. The same senior inspector gave her away instantly with some kind of grin that was incomprehensible at first.
I’m going to the regional FSSP (Krasny Prospekt 86/1), there is very strict security and access control, I had to hand over the knife to the shift. I end up in room 306, where a uniformed grandmother tells me that she has nothing on me and you go back to your MREO and get a “map of the restrictions imposed on the vehicle,” and here the senior inspector’s grin became clear. That is, the regional FSSP has imposed a restriction by initiating enforcement proceedings on the vehicle and does not know the number of this enforcement proceedings and cannot find it by the body number KARL!!! and this is in the age of information technology.
I’m going to the MREO, where the same senior inspector tells me that they haven’t dealt with these restrictions for 3 years now, that it’s absurd that he should tell me the number of the enforcement proceedings so that I can present it to those comrades who started this enforcement proceedings and sent them away it to the traffic police and now, having taken it to the traffic police, I must tell them this number. As a result of 5 minutes of such bickering, he finally prints out a map of the restrictions imposed on the vehicle, where it turns out that the regional FSSP imposed a ban on the previous owner of the vehicle (according to the PTS) on the old license plates (a traffic police fine of 500 rubles).
Then I realized my mistake when I bought a car from a seller by proxy 10 years ago, although the car was deregistered and in transit. Apparently in the database used by the FSSP, it was not removed from the previous owner.
I’m going to the FSSP (Red 86/1) I present a restriction card, PTS, passport, registration card, I receive a decision to lift the ban, remove the ban from the FSSP databases and send the data to the traffic police, where within a week or whatever, this ban will also be removed.
There was neither time nor energy to go back to the MREO to immediately enter the lifting of the ban into the database.

This is the age of information technology, and you still ask why there are such traffic jams.

Z.y. immediately ask the MREO for a “vehicle restrictions card”, they will admonish you that you don’t need one, we don’t want it, we won’t give it to you, but without it the FSSP will look at you with the eyes of a cow and won’t do anything.
