1 The retrofit of the CC to the Golf IV and Audi A3 TDI begins with the removal of the lower leftside (NOTE:possibly other side for RHD) panel and the plasticpart below which is fastened with seven Torx 20 screws. Then you just detach the pedal-cover 2 Removal of the Airbag is only for trained professionals. You can remove it by turning the wheel by 45 degrees. Through a hole in the backside of the wheel you then can snap off the airbag-module. 3 You can refasten the steering wheel 5 times at most with the same nut. Therefore you mark the nut with a [metal pin to mark stuff with hammer blows] each time. You can remove the nut with a 12mm wrench. 4 Though the wheel has markers for fitting, you should turn the wheel back into normal position before removing it. Then the steering column panel can be removed 5 The movable "ingnition line" for the airbag, the so called wrapspring, is clicked to the column and has to be treated carefully when removing and attaching. You can remove it easily though when you unhook both sides at the same time. 6 Wiper- and signal-stalk are attached to the column with a washer and a Torx 25 screw. Because there is an inner trailing rail you have to pull it off towards you. 7 While removing the stalks, you have to click off their plugs. Then you remove the indicator stalk and replace it with the CC part. 8 The CC-connection-line must beattached with the connectors first and after installment of the switchgear you have to attach the cable to the cable-binder on the left (RIGHT`?) side of the steering-column. Then the line goes further down towards the electronic box. 9 To get to the electronic box in the compartment in the engine bay, you first have to dissassemble the cover, the wiper arms, the complete wiper mechanics (3 screws) and pull it out. (In order of dissassembly) 10 Now there is enough room to remove the cover of the elctronic box. The black 10pin plug is the link between the CC-line and the TDI-ECU. Pull the plug and set aside. 11 Unclick the socket from the box and press towards driver footwell. Then connect CC-line to the socket from the bottom. 12 The cables of the socket are such in length to be able to pull it out and to turn it to read the label of the CC-pin 13 Connecting the cable-set is done by fitting the numbered ends into the equally numbered holes. 14 After reclicking the socket from the bottom into the electronic box the leftover single line is moved to the leftside connector and is attached to point 75X 15 After installation you have to activate the CC-function. This is done with the Tool VAG 1551 via diagnostic channel and function 08 or "login-procedure" with the codenumber 11463 Installing the new CC-line-set into Golf IV The set can be purchased with the part number 1J0 971 425 for around 12BP. 1 Pull fuse 5, unclick the cable for this fuse 2 Click cable into one of the plug parts (part # 191972701) 3 Click the short black/blue cable of the CC-line-set into the now free chamber of fuse 5 4 put both plug-halfs 191 972 701 and 191 972 711 together.
