T5 Cruise Control Failure

[Sunny43.5]

BrianJ You went to Austral ? after the way we were treated when we bought our new van I would never go back to them again , first free service was a total joke . I fitted the factory cruise control to our T5.1 other than the new stalk the only wiring to be concerned with is the one that goes to the relay under the battery [ what a pain that is to get to ] the other one went to a position on the rhs of the coumn , sorry can,t remember which one exactly but like most cars there could be two fuses associated with accessories.

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.

Yep, saw that when I went into the panel and straight to the lower half … the 5A fuse looked ok and I replaced it anyway. No change, still no go on the cruise control. I am guessing it is something more serious in the steering column.

Isn't that 30A SB9, SC9 the lower one is 5A and called 'Cruise control system switch'.

And now the lighter socket has failed … this morning will be a fuse by fuse check (just for fun) before I go any further. Will be making sure that all the accessory lighting and power is fused separately in the back of the van.

Whatever you do, don't turn on the ignition while any fuses are out being checked. I did this to measure voltages trying to find out why all my dashboard lights are dull and caused a load of airbag errors that had to be reset at the VW shop.

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.

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 .

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.
