It happened after disconnet the batery?
Normally the Audi cars when the KM are changed, the first time someone disconnect the car battery the dash goes off.
At my garage already had 4, normally Audi A4.

when we play with Chinese clones sometimes shit happens, especially when we do not know what we are doing.

Hello, I'm just starting... but I'm lucky that I also repair laptop, and I'm already familiar with flash memories (Bios), and MCUs (KBC in Laptop). Of course, as in all worlds, things are different. In fact, I have a 2001 Audi TT MK1, which, I have already successfully repaired needles and screen, but, I'm curious, and many friends who have a TT with a frame that gives problems, and I bought the Chinese UPA to start.
I bought some fenders from the TT at the junkyard and a friend gave me one from the Audi A3, which is identical to the one from the TT. The friend is upset. He didn't know about the heat in the MCU. Well now I have doubts, does this instrument panel have one or two MCUs? There is a small HC908, and next to it a larger one... It is that in some forums it says that it has two...
Then, with the UPA, I have read the HC908, and since I don't know the Security Bite, I get almost all the reading AD AD AD. I understand that you have to put something... does anyone know?
My painting, what happens to it, is that it does not start. These boxes, when you connect them at the bank (I have the cables made to connect it outside the car, and to connect with VagCom), turn on, beep and all that... in this case it turns on two or three lights, but does nothing. I'll try the heat and see what happens.
Well thanks in advance. I'm having a hard time right now, but I'm already playing with the UPA Scripts as well. As soon as I have one made, I'll pass it on to you. Thank you!
