Gasa XM 2.1 "Prestige"

...again a problem with the remote control, it doesn't respond to commands, most likely I will install an alarm and use it to remotely unlock and lock the car, at the same time I will have an alarm that makes noise if someone touches the car

The battery in the remote, the key is good, a new one was put in, everything worked for a while now it won't, I don't know what the problem is.

Infra-red, or Radio type remote?

The radio ones can be re-paired to the car.
Iirc, the procedure is enter car, place key in Ign and turn on, press button within 5 seconds.

The remote unit just activates the central locking by replicating the shunt to Gnd that the door lock performs. The fault could be the key, the pairing, the receiver, or simply poor power/gnd connection to the receiver.

..there is a radio signal, I will try to activate it again as you said, I wanted to make another key, but they told me that they cannot make that model of key, they cannot read the frequency, they can only device a key without a remote commands.

...the remote unlocking won't work, I'll solve it with an alarm.
I should have pre-sealed the steering rack, more precisely the part where the servo is, the gear on the rack, where the LHM oil is leaking, has anyone torn it apart, repaired it.

...in this marked place it releases oil.

It's easy to take apart, just a circlip in the upper side and the valve lifts out.

Make note of which grooves have the seals in.
The two outer grooves will have a seal, but only one of the inner grooves will and the positionis critical. Lhd have the central seal in one groove, Rhd have it in the other.

I'll see if I can find just the valve and change the rubbers and gasket on it, then just remove my valve and put the repaired one on my steering rack, so I don't have to remove the entire steering rack.

.. I was interested in something with the old engine mount, I noticed from the bottom that there was some kind of oil, silicone grease in the tire, I cut the old mount and I was right, only I didn't know that it also has a valve that serves together with oil for vibration absorption, the price of the mount is justified, it is not just a rubber mount.

..the whole space was full of oil.

That is what is known as a hydraulic engine mount.
The oil passes through a damper so absorbs the low frequency engine vibrations.
As long as it isn't leaking oil it will still be functioning, irrespective of whether the upper rubber section has collapsed. Obviously, the greater the thickness of rubber, the greater the overal vibration damping will be as the rubber and oil absorb different frequencies of vibration.

The rubber wearing down, or old, hard tyres, is the reason car tyres transmit more road noise into the cabin when they wear down. In the case of the engine mount, the rubber has compacted so become more solid, hence the interior engine noise is greater with "worn out" engine mounts.

Similar vibration dampening properties are used in glass.
Single pane plate, or toughened, glass passes sound vibrations through as the glass oscillates at the relevant frequency, whereas laminated glass absorbs (dampens) the same frequencies due to being a bonded laminate of dissimilar materials. Glass-vinyl-glass.
The dissimilar materials absorb different frequencies, so have a greater damping effect.

..if I didn't know that there was such a carrier, I don't have such a carrier on the BX, so this one was interesting to me because on the bottom side I noticed that there was some filling, not all of it in the rubber, that's why I opened it to see what it was about.An interesting solution and a good one.

..I also replaced the clamp supports, the right one had a little slack, now the front part is completely fixed.

...everything is in the center.
