Did I do anything...? Cruise Control experts advice .. and OBD2 software advice ...

[bundabora]

Hi

I have finally managed to squeeze my ans420 unit in and it is a beauty.
Not and easy install, but worth it.

I noticed this week that my cruise control isn't working though. Not sure if I could have affected something when installing the unit...? I wasn't fiddling anywhere except where the stereo goes, but I did have to push some wires around in there.

The Cruise control light switches on and off on the stalk, but the Set does nothing.

I found this thread and followed Jmac's advice -

http://www.vwwatercooled.org.au/forums/f14/cruise-control-problem-2001-bora-4motion-16285.html

I checked the Brake Pedal switch and it is working well, including powering off the engine (to an idle) and checked all the fuses.


I'll try the fix here next === VWFANATIC ===

I have some Proscan software, but it is refusing to cooperate with my laptop at the moment.

Has anyone had experience with OBD Autodoctor? I installed the demo version and it worked well but would only tell me about Stored diagnostic codes, not present ones - fair enough for a demo.

There was one stored one that was interesting - P0501 Powertrain - Vehicle Speed Sensor Range/Performance

If someone recommended the full version, I'd pay the $45 to buy it - or does someone recommend something else?

I just wondered if anyone else had an idea of my lack of cruise... If so, send it my way,

Thanks, Scott

Still could be the stalk you have to check the measured values while operating all buttons to see if they register a signal. And if its a manual you should also check clutch switch.

Grtuned is on the money i think

We were replacing stalks left right and center not too long ago, It sucks too because i ve had a few where it can read most functions of the stalk but will still not work, new stalk and works like a charm.

Hey you seem to be new here and giving a lot of technical advice. So what is your background ?

[jamesdavid]

Hey JustCruisn,

Just quietly i m a factory trained audi tech, i do work on volkswagens alot too however. That is to say where i work is just audi,volkswagen,skoda branded

Good to see another proper techie , your tech help is most welcome. I must admit i post a lot less tech now , one dont have the time and 2 well probably wont venture there.
Refreshing to have you here. Anyway i agree on the clutch switch if the brake pedal is checking out but i too have fitted many stalk switches.
Bundabora good luck, answered your pms as quick as poss but just cant get to all of them as the workload is off the chain at the moment. I would be seeking someone with VCDS and read the clutch pedal functions with live data. If the 2 switches to tally up as being ok its more than likely the stalk. Only other way its faulty is the Cruise is not enabled in the ECU but it really has to be physically coded out for that to be the case
Anyway good luck

Thanks Jmac! Good to be here. Yeh i m still a bit hesitant about what i post, i could ramble on about these dsg issues and the 1.8L turbo engine oil concerns but i can see it coming back and me left trying to answer a 'please explain' from the higher ups. But its good to know that there are techies on here too.

[Jmac]

Mate dont worry about rambling, i changed so many 20v engines in the very beginning due to oil pressure dramas and gearboxes? mate we were rambling about them backin MK1 and Mk2 so nothing has changed mate, they are great but like any other car theyhave an achilles heel.
Anyway Bundabora let us know how you go mate, as mentioned the clutch switch needs to be checked with Measured values therefore needs a good level of scanner, most good ones will read it but VCDS will tell you what you what your are reading if that makes sense.
Cheers!

Thanks Jmac, I just ordered a VCDS from Dubaddiction, for this and future needs, so hopefully I will know soon, once I understand the program... Cheers, Scott

[Speed]

I just wanted to say that I'm very grateful for all tech advice on this forum.
Jmac and Jamesdavid thank you for your posts. I appreciate reading them even though I don't have any issues with my cruise control.

[bundabora]

Thanks - do I use vdcs to check the measure values? Hopefully I'll understand what that means when my program arrives. Thanks again for the advice guys much appreciated

[jamesdavid]

Thanks Speed, its good to be able to share what we know with others on the forums, and being able to provide information that normally wouldn't be available.

Bundabora,

Yes, you need to be able to interrogate measured values of the cruise stalk, not sure on the setup of your scanner, i have always been lucky enough to have access to oem diagnostic software. Basically what you want to do is confirm that the steering column electronics is receiving the correct signals from the cruise stalk. I.e when you activate/deactivate cruise you want to be able to physically see the change in state, same for when you increase/decrease set speed.

Hope that helps,

James

I found the Problem! It was the Blue/White lead in the Stereo cables...

I may be wrong about some things, but here's what I think happened. I am hoping when someone Googles the same as I did,
they might come across this. After realising that Luke (Back Door Shenanigans) had the same problems as me - Cruise control not setting and Limited revving - 5200 rpm approx (crazy when it happens)

We both had this same error -
"Address 08: Auto HVAC Labels: 3Bx-907-044.lbl
Part No: 3B2 907 044 C
Component: CLIMATRONIC C 1.0.0
Coding: 11000
Shop #: WSC 31414
VCID: 224510A7AED4D09

2 Faults Found:
00281 - Vehicle Speed Sensor (G6
37-00 - Faulty"

After Luke had replaced his Speed Sensors he still had the same error codes. I was somewhat puzzled at this and found this :

speedo wiring.. imagewerx ? - uk-mkivs

I thought This could be my problem - my GALA wire in my install.

The GALA wire is what the oem stereo gets its speed signal from I think and it increases volume as the speed increases.

My recently Installed ANS 420 had a Big CAN BUS adapter that I couldn't fit my original Bora Stereo leads into, but they fit straight into the Headunit. Problem was, I noticed the adapter thingy dropped out the Blue/White Wire, but plugging it straight in messed up a whole bunch of things... I chopped and insulated the wire and the problems have gone and cruise is working again...

Hopefully there are enough Key Words like Bora, Cruise Control, Gala, sensor, problem, to help some folks and hopefully Luke gets his sorted out as well.

Thanks for everyone's help, amazing how all the ideas get you thinking.... Scott

4 times i'll put haha, Stupid mechanics throwing money at it first. Still unsure if its the same on mine, As i said before i will have to take my stereo out to get it fixed so will see if that fixes the issue or if the clusters the real issue. I wish i had my kombi back soooo much easier.

Cheers for letting us know a possible solution though. Will be a bit of a shame as then my gps will lose its accuracy.

glad it works Scott, thanks for posting up your solution
