Change the VW Roadside Assistance Number and Information Number.
I am not sure if this is set in the UK but in South Africa the numbers for the breakdown service and information service are set to the numbers in Germany. This is how to change them to local numbers.
For the Breakdown number
Go to 5F Information Elect
-> Adaptation 10
Choose Entering breakdown service number
The existing number will be something like
5E 07 A1 00 08 80 79 73 48 32 FF FF FF 0F 0F 0F 0F 0F 0F 0F 0F 0F 0F
You need to change the 4th byte onward and the numbers must be reversed in each byte
EG to enter the South African VW Alert Number 0860 434 737
The numbers would be reversed like this
08 60 43 47 37
80 06 34 74 73
So you would enter 5E 07 A1 80 06 34 74 73 FF FF FF FF FF 0F 0F 0F 0F 0F 0F 0F 0F 0F 0F
There has to be 23 bytes, you can just add FF to make up the 23 bytes.
The same principle is applied to the Information number.
