I had some problems wtih my older MK4, the gyro didnt work I dissasembled it and saw some water-damage, probably it was replaced by someone prior me buying this. I dont have the warranty with dealer because of this so I found a new MK4 on ebay. My older MK4 was from April 2003 and the newer I got from ebay was from July 2006.

Anyways the EBAY MK4 hade some problems reading disks so I reckon that if I buy that one and just swap the motehrboards it would work. So i did. BUT ...there was still a probelm the EBAY MK4 had modified software on it with M/// logotype and wouldnt read any DVD's. When I replaced motehrboards on teh working laser it still didnt want to upgrade. It recognizes the Software CD but I got the mesage which says something like

"Software-CD inside the reader. Software will be loaded" but then nothing happens and i get this 2 tiny green lines one above and one on the bottom of the screen, very hard to see. When I look at the clock I see that clock is not moving anymore in minutes, which tells me that the MK4 has frozen.

Is there ANY way, besides sending it to the VDO to make it upgrade or in my case, downgrade?

Thank you in advance
