Hi there.
A few months ago My Touch Screen Display started rebooting itself to the extent that it got caught in a loop. It would reboot, start up for about 20 seconds and then reboot again. I took it into a garage and they determined that it was what they called the Gateway Module that needed replacing. Based on the cost (and the fact that I didnt fully like the way they worked) i decided to see if I could do it myself. They left the Gateway Module out so that I could find a like for like replacement.
The part number for the item they had taken out was VUX500480 - which looking at the workshop manual appears to be the Integrated Head Unit (or IHU).
Long story short, I ordered a replacement IHU (second hand from EBay) and am now starting the work to fit it into the car. I’ve got as far as taking the dash off and have removed the Touch Screen Display. I’m pretty sure the IHU fits behind the Touch Screen Display.
Before I put it in and put everything back together, I wondered if anyone could tell me what needs to be done once it has been fitted? I understand that the MOST system is all secured by the serial numbers of the various components within the entertainment system and that if you replace one of those, and the new serial number is not known, everything will basically stop working. From my research it looks like I need to update the CCF file with the new serial number of the IHU.
Is that correct? And if so, do I need to keep the IHU accessible to access the serial number or interact with it in anyway? Or can i put everything back together and both read and set the new serial number to the CCF via the OBDII port?
And finally - although I suspect I know the answer here - is there a simple way for me to read and update the CCF without purchasing an expensive diagnostics tool?
