Ive been looking into this for almost 3 years.
And can tell you it's a right faff!. and you need a clock set of similar date and depends on PR codes as well...on top of Some VCDS work, you need another tool to extract the pin code from youre clock's and re-tie the keys/immobiliser.
If you have a low line setup, there is wiring to do also, assuming you want trip and CC stalks to work!
Has to said the highline clocks in the caravelle execs', are very sexy thou.
Im still looking for a set from a 07/08 donor to do mine, or over 600 for hazzydays, think i will keep looking.
