Probleme E-Verdeck mit VIDEO!

[Stout001]

Good evening everybody,

W A R N I N G - L O N G R E A D I N G

So this is how it looks on a 1994 electric cabrio with ABC motor:


The only relay that is not visible on the picture is behind 363 and has the number 217. I have visually checked them all and some had corrision so I cleaned them up. 363 is the control unit. I opened it up to checked inside but didn't find any cold or loose soldering. I will however put solder on the pins just to be shure. But when I push the central power windows button it is the one (#203) to the left of 363 that is making a strong click. Even if I change places on both 203's

After cleaning every single relay, I put them in place again and guess what, still no raising power windows

I know I have two relays in the back but they are not under the rear seat but behind the back support. I didn't have the time to remove it so that will be done tomorrow.


One more thing. My KL-interface gave up earlier so I can't do any resetting. I must get a new one and I know that the '94 ABC engine is crucial so at the moment I don't know which KL-interface I will get, one thing for sure is that the cheap blue interfaces with viritual COM is not working in my car.

Soon I will continue to investigate the errors of the roof. I did som tests tonight with VAG-COM and refering to Mechis aboslutely excellent MWB+Pruefschritte(gesch).
I have some odd things going on in the system. There are totally 14 steps (Schritt) and I completed 4 of them before the VAG-COM interface gave up.

Green numers are the correct values
Red numbers are the values to my roof
Blue are equeal values

Step 1
Verdeck geschlossen, Handbremse angezogen, Zündung an,
Scheiben oben, Kofferraumdeckel geschlossen, Kontrolllampe Verdeck aus.

OK (No fault)

Step 2
Drehen Sie den zentralen Drehgriff, ohne das Verdeck vom Dachrahmen
abzuheben

OK (No Fault)

Step 3
Heb den Spannbügel etwas vom Dachrahmen ab

Messwerteblock 1 (Eingangssignale)
- Gruppe 1 --------- Gruppe2
- 1 0 1 0 1 0 1 0 - - 1 0 1 0 0 1 0 0
- 1 0 1 0 1 0 1 0 - - 1 0 1 0 0 1 0 1
Comment: If I raise the roof a little bit further (approx 5 cm) I get a 0 as the last digit so there is no actual fault as the hood takes over when I push the roof button.

Messwerteblock 2 (Ausgangssignale)
- Gruppe 1 --- Gruppe2
- 0 0 0 1 1 - - 0 0 0 0 0 0 0 0
- 0 0 0 1 0 - - 0 0 0 0 0 0 0 0

Comment. Output is failing. I dont really know how to read the "Messwereblock 2" codes and what they stand for, anybody knowing?

Step 4
Taster für Verdeckbetätigung ziehen

Messwerteblock 1 (Eingangssignale)
OK (No fault)

Messwerteblock 2 (Ausgangssignale)
- Gruppe 1 --- Gruppe2
- 0 1 0 1 0 - - 0 0 0 0 0 0 0 0
- 0 1 0 1 0 - - 0 0 0 1 1 0 0 0
Comment: Same ouput signal, still don't know that the digits mean!

I will continue and present the complete "Messwerteblöcke nach Zustand" when I have the new interface. One interesting thing though, is that when the roof comes to the failing segment where the roof lid goes up (in the video it falls down, but not anymore as I have brand new gas-filled struts) everything stops and the back of the hood is slowly falling down. At this stage the Messerverteblock 2 (Ausgangssignale) is zero all over.
Messwerteblock 1 (Eingangssignale)
- 0 0 0 0 0 - - 0 0 0 0 0 0 0
should be if it was working
- 0 0 0 1 0 - - 0 0 1 1 1 1 1

In other words. there is no signal, system is dead! I can however pull the roof button backwards, to close the roof again. Strange, isn't it. Any tip on this is highly appriciated..

The other way around, when raising the roof from a locked roof-lid works excellent except for that the left and right locks does not lock, the griparms does not go down, therefore the boot-lid won't unlock. It could. Does the weight and closing of the roof making the lock (Verdeckkastenschloß) to actually lock?

This is getting blurry and real late. I stop for now and hope that you cabriofans can help me sorting this out.

Sorry, I exceded the 10 min editing limit time The Messwereblock 2 in Schritt 3 & 4 are wrong.

This was corrected above. Tux
