Problems with 1,2 Gearbox

[Martynas]

Explane please the part wit measuring blocks

[Mankmil]

Let me quote myself:

Could you please check the Measuring Block 003? Field 3 and 4 shows the clutch's actual value and the set value. If they differ, the ecu tries to trigger the clutch valve.

In Block 005 Field 4 you'll find the current running through the valve. It should be 0,03 to 0730A for the closed clutch and 0,800..0,900A for the opened clutch.

[Martynas]

I just bought another ecu, will see how it goes

[Mankmil]

Checking the Measuring Blocks was too simple?

[Martynas]

new ecu helped so I'm happy, but now I'm stuck with adaptation. when I start with 014 block and see adjust the upper potenciometer is impossible to move down so that it matches the whole? only if loosen the pressure it is possible to do that. So what shall I do? Loosen the pressure, and maybe put the bolt into that whole? but I'm afraid to damage something

[Martynas]

I can't allign this thing with the whole there, during adjust it does not move

[Martynas]

I moved it by force locked it with pin in the whole, then tightened the 13 bolt with the gear linkage being in neutral. And now during adaptation the robot moves up and down, but does not move back and forth and still I get 12. HELP

This part now isn't moving at all even with released preassure. Yesterday i did disassemble it, what could i do wrong for it to freez in this position? Or its normal and it shoudnt move? But the upper arm moves freely when there is no pressure

[Mankmil]

Just because I'm nosy: Where did you buy a spare gear ecu so quickly?

 

Towards your problem: Are you sure, that the carrier on the 'potentiometer' fits into the slot of the actuator?

 

Your picture shows the slot of the actuator:

 

You could check this in Measuring Block 015/3 -> this value should correspond to the positon of the part that doesn't move on your actuator.

I bought the ECU from local junkyard for 44 eur.

And yes I'm sure that i did put into the slot, what I'm not sure is the part inside the robot that is easy to put on in many different ways, but I followed the pictures that weisse a2 provided and did put it on accordingly.

Will check that 15 block you suggested and will come back. Thanks

[Martynas]

015 block values

first box 4,20 v

second 0,00 v

third 2,44 v

fourth 2,94 v

 

what does it say to me?

[Mankmil]

3rd box is the position of G239 (the lover potentiometer belonging to the arm that doesn't move on your actuator)

4rd box is the position of G240 (the upper potentiometer)

 

If you move the actuator manually, both values should change between ~1.0V and 4.0V.

But at fist glance, both values are looking good.

 

Are you sure, that you connected the valve's plugs correctly? Did you mark them?

[Martynas]

I didn't dissconect them, but how can i check them? Its strange that icant move the lower one even with pressure released

[Mankmil]

If both cylinders are filled with oil and the reflow is blocked, you can't move anything.

[Martynas]

So it's normal?

[Mankmil]

No, I don't think so! Something seems to be wrong with the valves or the arm is blocked by sth. mechanically.

 

You should be able to move the actuator manually when the system is depressurized.

[Martynas]

Ok so will take it off and disassemble once again. Because upper arm moves freely.

[Martynas]

These things are stuck on this position i cant push them down and even when i try to pull them out vacum is holding them there ... It sucks it back

disassembled put everything back, but now on 015 block I see 0,47v on third and 2,09 on the last one.... is it ok?

In 014 block wait doesn't change to adjust

[Mankmil]

015 block I see 0,47v on third and 2,09 on the last one.... is it ok?

 

This is definitely out of the tolerance range (0,47V - allowed are 1.6 +- 0.4V ... 3.8 +-0.4V). Either you assembled the rocker in the wrong position on the shaft or the carrier doesn't fit into the potentiometer's slot.

[Martynas]

when in adjust mode on 014 block everything should move easy or with resistance?

[Mankmil]

I'm not sure, but I think in the "Adjust" Mode the actuator is pressurized and driven into its neutral position. I this mode you shouldn't be able move anything.

Then you release the connection to the gearbox and put the gearbox in neutral position too. Otherwise you won't get a "Grundeinstellung".

 

But that's only what I expect from a "Grundeinstellung", I haven't tested it.

[Artur]

@Martynas: May I give you a word of advice?

 

Search for the 'Self-Study Programme 221' on the I-net (SSP_221.pdf). It's rich of basic principles of this electronic manual gearbox.

[Martynas]

I have it Arthur, doesn't help much with practical questions

[Martynas]

I read the 221pdf Arthur suggested once again, took the potentiometer off, now the voltage is 2,99 and 2,09, but when I launch adaptation there is no movement :(yesterday at least there was up and down. And again even if I release the pressure the valves keep holding and not letting to move the lower leg

You start the basic setting with gear lever in tiptronic-mode, at point adjust you move the lever over to E. Now you can open the nut at the long hole under the gear selector. The gear selector now will get in the right position by itself (you can't move the rod by yourself, that's ok). After that adjustment go back in the car and put the gear lever back to tiptronic (don't shift into N!). The basic setting will continue automatically.

[Martynas]

I did that 100 times already it all end up with the 12

[Martynas]

I give up. Bought this Lupo from my friend now, and now it's my problem, not hers. I think I will do the "umbau" auf mechanic.... any good links you know?

[ecoangeluk]

Take it to Dennis in Denmark or a German garage that knows the 3L

 

Dennis : djmail at stofanet dot dk

 

 

He has fixed A2 1,2 and Lupo 3Ls since they were first available.

[Martynas]

Hello, how to recognize A2 1,4TDI ECU?

[Mankmil]

By checking the part-no.

 

AMF: 045906019AT, 045906019G

BHC: 045906019BA

ATL: 045906019F

----------------------------------------

ANY: 045906019, 045906019BL

 

If you need a suitable ECU, contact me.

[Martynas]

Mankmill maybe you know how to reprogram lupo ECU so that it works without gearbox ECU?

[Martynas]

By checking the part-no.

 

AMF: 045906019AT, 045906019G

BHC: 045906019BA

ATL: 045906019F

ANY: 045906019, 045906019BL

 

If you need a suitable ECU, contact me.

 

Hallo, ale A2 1.4TDI haben VNT turbo?

[Phoenix A2]

Hallo, ale A2 1.4TDI haben VNT turbo?

 

Nein, nur 1.4 TDI 66kW (MKB: ATL).

[Martynas]

Nein, nur 1.4 TDI 66kW (MKB: ATL).

 

Aha OK, ich brauche den program von diesem ECU then, wo kann ich es kriegen?
