Hi all I have a 1.8 16v with no message centre fitted, can I just but a cluster with message centre and fit it or do I need it hooked up to a T4 (Testbook version 4.Computer Diagnostic System)?.
It needs to go on a T4. And be careful you can't just buy a used one of the bay, it needs to be a new one. There are some people who can reset a used one to new ready for matching.
