As many will know, I am a self-confessed cruise control addict. Most of the cars I drive on a week-by-week basis have cruise control, as does my A2, of course. I've got so used to driving with cruise control that I really don't like having to keep my foot on the accelerator for hour after hour when motorway cruising. Not infrequently I'll have to drive an A2 other than my own from one area of the country to another, and there's no guarantee that it'll have cruise control. So, I've devised this neat little cable that allows me to add basic cruise control in 5 minutes!
First of all, apologies for the poor image quality. The cable is powered from the cigarette lighter and is based around an old ASR switch. Three pins need to be inserted into the engine management unit under the passenger's foot well. Once plugged in, the light within the switch illuminates to indicate that the system is ready to be used. The switch hangs conveniently by the hand brake.
The single switch mimics the 'set' function of the full cruise control installation. So, once the car has been brought to the desired speed using the accelerator pedal, the button can be pressed to hold speed. Your foot can then be taken off the accelerator and the car will continue to drive along at that speed.
Cruise control can be cancelled by either tapping the brake or the clutch or by simply removing the plug from the cigarette lighter socket. Unlike the full installation, there is no resume function, meaning that cruise must be set again if cancelled.
The cable's internal wiring isn't overly complicated. I've drawn this diagram to demonstrate how it's been made.
The cable works with all A2s other than the 1.2TDI. It has made many a long journey much more comfortable.
Cheers,
Tom
