T5 Cruise Control Failure

[Silver Caravelle]

Hello,

I have had the same fault as Brian describes. Cruise control works, until I move the indicator stalk ever so slightly now. Use to be only indicator down in left position, now does it most angles. I haven't bothered to swap out the indicator/wiper stalk as yet.

Yes, I had reached desperate after an auto electrician near Kedron almost wrecked a loom and still didn't work out what was wrong. Even though I am wary of dealerships, they were able to source the only suitable blinker stalk that was in Sydney at the time and fit it without drama. I would have done it myself except I have no experience with playing around with airbags.

Fair enough , in my job I work with airbags a fair bit so I know the respect needed [ admits here that when I did the cruise I managed to stuff up the clock spring on the back of the steering hub } I was fascinated on how it worked and when I put it back on it was half a turn in the wrong direction so when I turned the steering wheel to the full lock in one direction it ripped the ribbon cable clean off the clock spring DOH ] yes dealers can be a pain I now use an independent company at Underwood as they are really good and honest with repairs and service .

… this morning will be a fuse by fuse check (just for fun) before I go any further.

Nothing found in the full dashboard fuse check … all are in good order. Searches on UK forums suggest there is a fusebox under the front seats which I don’t see … or is what I thought to be a set of plug connectors hiding something more complex?

Edit: found a YouTube video with the fuse shown under the front side of the passenger seat … had a look and sure enough there is a few dusty fuses under there - one of them the blown cigarette lighter fuse. Fixed but still no cruise control (tomorrow’s job to clean and check all the under seat fuses!)

I dont think this would apply to your model but on the T5 upto around 2012 there was a series of connectors under the front drivers seat, not sure what thye controlled but on that model they had a nasty habit of growing green corrosion on the pins and that would stop certain things from working . I could never figure out how connections under the seat mounted off the floor would get corroded as no water gets there . Maybe Watch this video as he shows the whole fitment procedure How To: Install Cruise Control Into Your VW Transporter T5.1 or T6 - Overview of Installation - YouTube and I noticed on one of the power wires there is a built in fuse at 7 minutes 47 seconds which might be what your looking for.

That was all a bit too much for me! I can see the fuse you refer to in the video, but at that point he appears to be deep in the bowels of the dash and I am not up to pulling all that out on the off chance that it is that fuse causing the problem … I am going to have to hunt down a local expert to solve this (eventually) or just live without cruise control.

Hi Vaughan,

If fuses are okay, could be the cruise control switch on the indicator stalk or a faulty wiring or contacts within the stalk.

Cheers,

Thanks, that seems to be the consensus across the many YouTube videos on the subject! The T4-5-6 steering stalks seem to generate a lot of concern for people.

Its not that difficult that guy went way overboard with the whole instrument cluster out , I can only recall removing the lower dash panels beside the steering column and the connection point was right in front of that area .

Ah OK, I see that bit now … I have had the side of that part of the panel off to run cable for the HUD, so it might not be too hard to spot the in line fuse from the side. Repair Cruise Control project remains ongoing!

I get most things done by German Autos at Geebung on the northside of Brisbane, they are trustworthy and do quality work.

They still around. They were my goto for my T2 Kombi.

Thanks, not sure I am up to that level of repair myself … but will keep it in mind when I finally get around to talking to an auto electrician about it. I have a feeling it must be in the control stalk or steering column wiring. All the fuses I can find seem to be OK.

In my 2007 T5 the cruise control was factory fitted and failed at about 150000K. Replacing the clutch switch (easy job and cheap part) fixed the problem.

Another thing to conside as it happens from time to time with my T5 2005 model a light in the instrument cluster comes on and the cruise wont work EPC . Mostly it goes away on its own after short time and the cruise works again , sometimes I wish the other three would go away by themselves but the van has /Engine Check light / ABS / Traction control on for around ten years now but again the van just wont die .
