Mate, highline is something I wanted. How much is it?
Still awaiting for the group buy for vagcom and there's been no result so far.
id say it would be a dealer only job due to the age of your car.
the newer models are near impossible to code (immobiliser) due to obvious security reasons with swapping clocks.
The older models 2005-2006 are doable with something like vag commander. As far as im aware, the immobiliser tools available for newer models, just isnt up to the job yet.
there are solutions available, but they cost a fortune.
so basically..it will cost about 250-400 for your clocks from the dealers, then about 1-2hrs labour for coding the clocks.
it should only take a dealer 15-20minutes to do but they will charge you more.
