Hi,
Managed to take down the selespeed pump and to change oil.
Took us a couple of hours, but now that we know, it's a 2 hours job.
Removed all selespeed oil from oil tank with a syringe.
Can't describe it in details, i was just support, my god-father did all the hard work.
Most of it it is hand coordination, u can't see nothing. Pump has 5 screes, 4 holding it, 1 for oil bleed. Accessed the screws from under the car and driver side wheel place (took wheel off). Took the pump down. The connector for the pump is on the left side as you look at the selespeed oil tank, disconnect it. Also there you can see the relay of the selespeed pump.
The pump is half of a normal king size cigarette pack, rest of it it is the electromotor (electric motor). (The nipple you see from above is the electromotor and pump is attached to it - bottom side)
During disassembly we hit with a wrench a screw which didn't want to come off and noticed the pump is working. So it was the electromotor which is turning the pump.
Disassembled the electromotor and it was filled with black dust from the charcoal brushes (brushes look like a 90 degrees angle parallelepiped). The brushes were small. Took the brush out (careful with metal holding the brush, can be broken if operated hard) and called it a day
Next day we hit shop after shop to find replacement of those brushes. After 3-4h of search we found one almost similar (1.2 euro). Cleaned the inside and all parts of the electromotor with air jet.
Replaced brushes, tested pump on car, fitted the pump back on, put oil on, car works perfect. Will monitor it for a couple of days.
Total costs = 26.2 euros
brushes = 1.2 euros
cs speed oil = 25 euros (2 liters used only 700 ml)
