Petrol cruise is totally different to tdi cruise. Petrol is vacum, tdi is electrical. You need to check: For a switch (almost the same as the brake light switch) on the clutch pedal. (get a torch and practice ya yoga :lol: ) Take off the top and bottom steering colum surrounds, and if there is a black connector plugged into a blank socket near to the indicator stalk connector, you can add cruise control. Buy a 2nd hand stalk unit with the cc switches & swop it over for yours (Disconnect the battery first, as you'll be pulling about very close to the airbag) Next, get vagcom or pop along to ya local VW/Ford dealer and ask them to put in the 'login in' code to activate it. I know this works, cos I did my TDi yesterday :D
