VW T4 Camper Van Build 12 | Fitting Cruise Control to VW T4 Transporter 2.5tdi

If there's one feature I missed on longer trips in our camper van, it's cruise control.
All of my other cars have cruise control and it's vehicle option that I find extremely useful especially on longer journeys in my VW Transporter T4 when you're mile munching.
Thankfully, all of the main components are already in the van as standard - the later model ECU has cruise control, the loom has the plug connector - however the cruise control needs to be enabled using VCDS, and you need a loom to engage & disengage cruise control.
Getting it all to work is simpler than I thought. See the steps below that I followed.

Of course finding a factory T4 cruise control stalk is like winning the lottery, but it's easy enough to make a loom like I did to get it working or get one from one of the few people who are making them so owners can retro fit them to their vans like I did.
There's a simple check you can do to see if your van has cruise control ability - start the van and idle, apply some revs (I think it was to more than 2000rpm) then at the same time apply the brake with your left foot - if the engine drops it's revs automatically you know you have a van that can have cruise control activated.
There's a simple procedure to activate Cruise Control in VCDS - log into the app, and go to Engine module then click the login button. Enter 11463 to activate the Cruise Control software option in the ECU. It's that easy....

I hope you get inspired to do something similar in your van conversion!

Wiring - credit to Steve Lou on Just T4's for this info:
Check you have ECU throttle control: when parked, gear in neutral, increase revs to 3000, press left foot on brake without changing pressure on throttle, and revs should come down. If they do, you're good to go. If they don't, then buy a house brick and that's your cruise control.
Step 1 - Buy The Bits
2 way momentary
www.ebay.co.uk/itm/281811473142
On/off switch (not needed if you are hard wiring 'on')
www.ebay.co.uk/itm/254230113995
You'll also need some wire and crimp female terminals for the switches.
Step 2 - locate the connector
Remove the fuse box cover panel (to lower right of steering wheel). Undo the brace and bottom plastic cover. Remove side clips from the relay block and lift up the block and lower down out the way. The connector will be located at the back near where the loom goes through the bulkhead (see pic)
Step 3 - Start connecting up
On the connector you'll see numbers stamped on the side, this relates to the numbers in the wiring diagram (see wiring diagram). You can cut the wires and use wago connectors which I found much easier and wire as per diagram.
Step 4 - Mount switches
Decide on where you want the switches and mount according routing the wires neatly behind the dash.
Step 5 - Activate with VCDS
This can be purchased with a cable for about £10 on eBay.

Amazed at how you get those finger to be so nimble in that small living space, well done. I love the faith shown that it was just going to slip in perfectly without any pre test or adjusting. One shot. Love that there is a perfect slot to put the buttons on the dash. Happy cruising!

[@AdventuresAutomobiles]

thanks, it all worked out rather well!

[@cannaroe1213]

Absolutely fantastic video! Really making the most of UA-cam :) Doing it next to what sounds like a busy highway added drama and suspense. 10/10
If you want the CC switch for safety/redundancy (because you could easily have it always on) I highly recommend you tap into the fuel-pump cut-off solenoid on the Bosch pump, because that cuts fuel period. Pulling the keys out should do the same. There's also a manual shut-off on the pump (for during tuning/setup) but I don't wire up actual wires that'd be silly.

Big Thanks ;) !!!

[@AdventuresAutomobiles]

No worries!

[@dawnhood8879]

Well planned and executed.

[@AdventuresAutomobiles]

thanks!

[@hoodlum1107]

Nice and simple!

[@AdventuresAutomobiles]

It was much easier than expected, which is always nice.

Hello! Do you have wiring diagram?

[@AdventuresAutomobiles]

Here is some more info and a wiring diagram: adventures-and-automobiles.com/vw-t4-camper-van-build-12-fitting-cruise-control-to-vw-t4-transporter-2-5tdi/

[@doogeey6mluca421]

really interesting video.
But I'm perplexed...
...only applies to the VW T4 TDi (Diesel)
or even for the 110CV petrol?
I have a 1993 T4 petrol 110 hp 5 cylinder.
Does this also apply to my model?

[@AdventuresAutomobiles]

I don't know for sure, try T4forum website. I would be surprised if you couldn't add cruise control like this. GL!

[@Bissela]

If you have an electric gas pedal, it might be possible. 🤔

[@mikewoodgate3127]

Why haven't you explained that you need to reprogram the on board control unit with a VCDS or pay a stupid price for an official dealer to do it. Also it can only be done with a 2.5 TDI that you have previously tested by holding the revs at 2000rpm then touching the brake or clutch pedal to make sure that they drop, in all seriousness your explanation is the pitta

[@AdventuresAutomobiles]

Thanks for chiming in Mike. The video is not a "detailed how to" - I just showed how I did it and that it is possible with the 2.5tdi (which I have). I don't talk about other T4s as I can't share my experiences with other engines - so my context is always my T4... I'm looking forward to seeing your video and explanation soon to help benefit the T4 community. Don't forget to drop the link in the comments to show us all the details.

Why don't you read the guys description before being an arse mate? He mentions how to test the brake peddle and the subject says "Fitting Cruise Control to VW T4 Transporter 2.5tdi" -
