On second thoughts, the 5f module is the module you have removed when you installed the Pioneer, so you won't even see that module in VCDS.That's great, thank you, will have a look![]()
There is a however a canbus adaptor for the pioneer head unit, but not sure how much functionality it provides, or do you alrday have that ?
something like - pioneer CD-SVW-UAR.006AE Vehicle Bus Information Instructions that is specific for your van.
