Basic setting RTFM 12

[sasha]

Good day,

The car is A2 2005 1.2tdi.  I have got a problem with the basic setting, the error is RTFM 12. 

The lower lever of the selector was broken (it was welded earlier by previous onwer, but the work is carried out not quality and it is broken once again ).

After welding the lever is mounted again,

I suppose the position of it is right because I try to act accordning to the inctructions of this forum and wiki.

Now after 2 cycles I have got the RTFM 12, before repairing it worked properly.

1. The Errors are not present.

1. Rare lights turn on 5-8 steps on each cycle, then they turn off.

2. Manually all gears are sellected with out any problems,

the indication of G240 is 3,9V-2,9V-2,1V-1,05V (the percents is normally too),

the indication of G239 is 1,5V-2,65V-3,9V (the percents is not so good, about 85%-45%-1-2%).

I move a little (right left) the flag of G239 the voltages also a little change, for example,

1,6V-2,75V-4,0V (percents recalculate, but lower border (2,4 gears) can not achieve 100%-90%)

I noticed, if I manually overcome the resistance of the gearbox shaft spring and continue pulling the lever to the left,

I can reach about 95% of G239 (2,4 gears) , but this is not  fixed position.

If I shift the lever on the shaft on 1 tooth left or right I can not select all gears. Thus I suppose it is only one right positon of the lever

(the working area of the lower lever without connecting to the shaft of the gearbox  is about only 4 teeth)

Can this cause the error RTFM 12?

3. The voltage of clutch cylinder is about 1,95V and 4,0-4,05V accordingly

4. During the procedure of the basic setting I can see under the car due to the long cable

that all gears are selected  R-1-2-3-4-5, then N between the 1st and 2nd cycles and once again R-1-2-3-4-5,

on the FIS indicator chooses step by step 1-2-3-4-5 and stays on the 5th until starting of the 2nd cycle.

 

Could you advise something? Thanks.

Wiki says:

 

The shift finger or shift rod on the gear actuator may be incorrectly adjusted, or the measured values may fall outside the specified tolerances; check the shift finger assembly—refer to the "Adjust" procedure. Verify that the ball joints are correctly assembled and securely seated. Check the potentiometers (see RTFM 10). Ensure the valves are securely seated and leak-free; also, verify that the valves are connected correctly.

It may also be helpful to lift or free up one of the front wheels so that gear changes can occur without resistance, allowing the basic transmission setting procedure to be completed successfully.
