How to retrofit/install cruise control on a VW New Beetle (1998 on) This is meant as a guide only, I am not responsible for any damage you cause to your vehicle. Only for Petrol Engine Codes; APF, AQN, AQP, AUE, AVU, BDE, BEH, BFH, BML, and 1.9 TDi Diesel Engine, with Electronic Throttle Control (ETC) Other engines require extra wiring harness not covered here. Parts required... Indicator Stalk part# 1J0 959 513 01 C Available on ebay, as a kit, or buy the parts from your local VAG dealer Tools required... Torx 20 and 25 Stage 1 - Battery Disconnect the EARTH lead to the battery. Stage 2 - Under dash wiring harness Remove the dash side panel , near the driver's door, and front panel (beige colour in this case).
Take the end caps off the seat heater controls (blanks on cars without heated seats) and remove the 2 screws behind. remove the 2 screws from underneath pop the circular cap off and remove the panel screw below. Pull the switch panel forward and remove the final screw on the right Next remove the 4 screws underneath, in the foot well, and unplug the light switch and fader wires. The relay rack needs to be removed, to access the T10e socket from underneath, it's held in by 2 x 10mm nuts, 1st next to [53] and to access the 2nd it's easier to remove relay [192]. To get better access to the rear of the fuse box, remove the 2 screws and pull it through the hole towards the driver's door. From the back of the fuse panel push the blue/black wire into its holder whilst pushing the paperclip in from the other side, then gently pull the wire from the back of the fuse box. Plug the blue/black wire from the new Cruise Control harness into the back of the fuse panel where the original wire was removed, then the original wire from the fuse panel into the new Cruise Control harness. To make more room pull any unplugged wires out through the hole above the fuse box. WARNING: be very carefull not to close the drivers door whilst these wires/connectors are exposed. Stage 3 - Upper dash wiring harness Remove the top centre dash cover, it just slides forward, easier if you wear a pair of rubber gloves. The right dash cover will lift out with a bit of persuasion. Underneath there’s another cover held in by 6 screws, 4 along the front edge of the pimpled dash and 2 to the left nearer the windscreen. This also requires a little coaxing to lift out. Now you can see the top of the junction box held down by 2 x 10mm nuts. Remove the nuts and lift the top up to reveal the colour coded connectors. I found it easier to unplug them all and move everything over to the left, out of the way. Next release the Black T10e socket from the rack, 1 clip either side, and push it through so it’s accessible from under the dash. From inside the car you can feed the T10e socket through to gain reasonable access under the dash, it's just too short to reach all the way and you may need a lamp/torch to see the numbers on the socket. Sorry forgot to take pictures for this stage. With the socket pulled through as far as possible, before inserting the wires from the new harness you need to release the purple locking bar on the socket. You can see one on the blue plug above. It only needs to be moved 1 or 2mm using a small screwdriver to prize it out on the end with the horizontal purple bar, not the purple T. The wires from the kit go into the corresponding numbered holes, 1, 2, 3 and 9. Stage 4 - Steering column To remove the airbag you need a small, flat head, screwdriver with an approx 80mm shaft. Unplug the airbag, yellow plug and 2 earthing wires, and put it to one side.
To remove the steering wheel you'll need an M12 Spline socket. I borrowed one from my local garage (thanks to Craig @ Llantrisant Garage). Next remove the steering column shroud, 2 short screws to the front, 2 long screws underneath and a larger head screw beyond the column adjustment arm handle. To remove the bottom shroud you need to push the adjustment locking arm down and remove the handle, 2 screws, then prize the bottom shroud lose from the left hand slide and out to the right over the ignition. Next detatch the front box from the column stalks, 2 clips at the top (not shown as this is a bottom view), tape the circular section to the box to hold it in place. Slacken the locking screw (25 torx) and pull the column stalks forward to gain better access to the wiring, unplug all the wires. Slide the column stalks off the steering column. To split the stalks there's 1 clip to the right of the circle, they'll then just slide apart, left side forward. Replace the old indicator stalk with the new one. Rebuild the steering column and front dash. Stage 5 - Enabling Cruise Control To activate Cruise Control you'll need VagCOM and the lead to connect to your car. If using VagCOM, start up as normal (plug into pc/car, turn on ignition, start program, click - options, test port, apply), click on Select. Click on 01-Engine Click Login-11 Enter Login Code 11463 and click "Do It!". If you ever need/want to deactivate Cruise Control follow the VagCOM instructions above entering the login code 16167 That's it, assuming all went well, you now have Cruise Control.
