alan_131 Posted June 20, 2012 Report Posted June 20, 2012 My late '99 built manual tdi 110 ghia is suffering from lots of unresolved problems, amongst them is the cruise control is u/s.(It was like that when I got the car). Browsing the forum pointed me at column/clutch/2xbrake switches, so far I've just looked at it with VCDS-lite - and it seems to see things ok - at least, operating the switches on the stalk or pressing the clutch/brake pedal flips what I assume are the relevant 0/1 settings, and it's coming up 0.0 in the short coding (all switches off/pedals up) which I think means it's enabled. My bulb failure unit says the brake lights are working ok too. My speedo is fine so I'm thinking it must know I'm going over 30? Wondering if being in limp mode can stop cruise control from working, or if anybody has any ideas where I should look I'd be really grateful... Quote
gravesyt Posted June 21, 2012 Report Posted June 21, 2012 I had something similar on my 98 110 bhp it turned out to be stalk switch got it flea bay £8 bargainhope this helps Quote
alan_131 Posted June 21, 2012 Author Report Posted June 21, 2012 Interesting.... I didn't think it was the stalk - because vcds can see the switches change - but if I can get one for that sort of money might try swapping it out anyway. I'd assumed it would be too expensive just to try so thank you very much. Quote
alan_131 Posted June 21, 2012 Author Report Posted June 21, 2012 Prompted by gravesyt I found a reference on another (vw)forum about this. It says in vcds engine blocks 6, column headed (Cl/Br/Re/Ac/on/on) should have a "1" under the "on" next to "Ac" - mine is 0 all the time. Apparently this shows if there's a power supply to the cc memory and it doesn't work without this. I was wondering if anybody can tell me if this is right for our cars too please? Quote
alan_131 Posted June 22, 2012 Author Report Posted June 22, 2012 Update: Gravest was spot on - thank you! I finally did a bit of old-fashioned investigation and instead of vcds used a screwdriver. Taking the cover off the column, I can see that one of the wires from the switch has worn through where it feeds past the mounting pivot. I'd thought because all the apparent switch positions had a corresponding effect in vcds it was working, but should have done more research on the field that wasn't changing, and also checked to see if my understanding of what the column switch did was complete.

ARSENAL79PLACE Posted June 28, 2012 Report Posted June 28, 2012 Did your cruise light switch on in the dashboard display? Quote
