holy crap! a 5 pound vagcom cable (chinese clone with vagcom 4.09) and vag k- plus can commander version 1.4 and you can do it yourself! i actually done this job without the need for the skc from the old clocks as you can pull it from the ECU with vag K- plus can commander and that cheap vagcom cable... than when you have it you just go into vagcom and follow the steps as found here on the forum or as they are described on the Ross-tech wiki... ( but that means you'll need a laptop running windows with at least one usb port)
it sounds hard but it deffo isn't if you can follow a cake recepie than you can do this yourself if you have the right stuff... and if you can't because you don't understand it any youngster that is computer savvy will be able to do it or you .. you just have to get the cable of eBay and the rest of the software is just a google search and download away
otherwise find another garage to have it done, there are vw specialist garages everywhere they'll do this for you in an hour or so...
