Default Help with the PCM2

The PCM2 SIM card tray from Becker USA finally arrived to my home. (In Spain Becker didn't want to sell me any parts)
My PCM2 had it broken. I did the replacement, and followed the instructions from this DIY:
http://www.renntech.org/forums/index.php?showtopic=9559


When I connected the unit to the car, the PCM2 didn't work. A friend of mine (electronic engineer) helped me in dismantling again the PCM2. He checked up all the connectors and mounted again the unit. All seems to be correct
Then we went to plug in the car and the PCM2 was out of work
We decided to go out with the car for a while and show him the excellences of the 996. 10 minutes later, suddenly the PCM started working. It began to play the 1st disc from the Compact disc changer, in a loud volume. The new SIM card tray worked too, as we could see the phone operative. The only thing incorrect was that that the keyboard didn't responde...

Then we stopped the car, disconnet the battery for 15 minutes, and after that..... the PCM2 worked!!!!!!!!!!!!

I could update the hour, date, check the phone list, change 3 or four times the CD changer, selected the new radio stations, etc.
I checked the Navigation sistem too.

Always was perfect...!!!
But 15 minutes later , the PCM2 suddenly seized up.
We couldn't do anything more because It was blocked in a radio station...

Finally we deciced to continue the next day.
The day after the battery was dead. Almost 4 years, .... normal.... a normal battery life...

I purchased a new one but the PCM2 continued blocked... Then I disconnected the PCM2 unit from the car till I could find the solution.
All the fuses were correct, the wiring, the connectors... so what could I do?
I went to see a frind who purchased the Durametric Tool last week, but we didn't know how to solve the problem
The durametric offered a PCM error, but no how to proceed.

I decided to check it other day because we have no experience and I left the car parked in the garage
3 days after I went to get the car, but the new battery was completely dead. I went to the shop and thanks to the warranty, they replaced me with a new one.

What can I do?
Why the PCM2 can't work?
Why the battery is at high risk when the car is parked and closed?

I'm getting mad.
I read lots of post about PCM2 troubles
I could see that there is a way to plug the wiring, and I read that some people had the same battery issue too

Please help!!!!


Thanks in advance
