Passat (B6) :: Intermittent Cruise Control Failure Due To Dying Battery
Dec 5, 2011
We began to get an intermittent cruise control failure (big exclamation point in the lower left of the MFD and no green "cruise" when the lever was clicked to "on") in my wife's 2007 2.0T Passat several months ago. During the same period she told me that the car occasionally didn't want to crank...although it always started on a second try. Well, to make a long story short, I had the battery replaced at the 60K service a couple weeks ago and the cruise has worked flawlessly ever since.
I put two and two together just before I took it in for service when the car showed failure of the antiskid system in addition to the cruise following a particularly difficult start. Sure enough, the new battery fixed it. Apparently some of the accessory systems go into a failure mode when they don't get enough current on startup.

I have a 1999 VW Passat that has a problem with its cruise control that two dealers have not been able to solve. Most of the time I cannot engage the cruise control. Other times it will work properly for 30 minutes. On a rare occasion, it will work properly for several hours. It does not seem to matter what type of road I am driving on. On the rare occasions when it works properly, it does not seem to matter if I stop the care and shut off the engine.
It appears is is there are times when it stops working that stopping the care and shutting off the engine is useful when I begin driving again. However, there is nothing consistent about when it fails, and when it again functions. The dealers have said little more than the cruise control is not working. One dealer installed a new break pedal sensor which did not resolve the problem.

My B5 1.8t 5M cruise control has stopped working. It became intermittent for a while and now it is dead. I have a long commute and really need the cruise to work.

Battery kept dying. Had the battery tested. Bench tested as OK but kept dying. Replaced the battery with a new OEM. In a week, that battery was dying too. Alternator was putting out 13V but would dip down to 11V. Also did a parasitic current draw test. Car is only drawing 20mA at rest. Replaced the alternator with brand new. New alternator putting out 14.4V. Battery keeps dying. Still no parasitic current draw.
I did two things right around the same time I started having the issue. I put in a new head unit. I already had an aftermarket head unit and I simply upgraded. I know this isn't the issue because I ripped the thing out completely, including wiring harness, and I still kept having a problem. The other change I made was going from a MFSW to a 3-spoke. I removed the MFSW relay and switched the pins in the column so that the horn and airbag work properly. I tried the cruise control and it doesn't work. When I try to turn on the cruise control, it blows the horn fuse. Replaced the horn fuse and I just don't use the cruise.
What I'm wondering is if I messed up the CCM when I did the steering wheel swap. I've read that bad CCMs can kill batteries. I'm not having the typical faulty CCM issues. The only issues, besides the battery dying, are that the unlock on the keyfob will stop working at random, and the "door ajar" light on my dash flickers at random.

I have a Ford F150, 2003. I replaced the switch above the master brake cylinder just a few months ago soon after I bought the truck. I put 17" rims and new tires on my truck and now my cruise control works intermittently. It worked fine before then.
Can there be a connection between the intermittent failure of the Cruise and the larger rims and tires? I know my speedometer is off by about 4 MPH at 55 but I expected that.

For about 6 months the cruise control on our '09 F-250 has been intermittently failing. One time I'll set it and it will work fine, the next time I try to set it and it fails. No particular rhyme or reason to when it fails to set.
Some of the tests that I did indicated it was the brake light switch on the brake pedal arm. It seemed to work perfectly a few times that I drove it after the installation but now it's back to working when it wants to.
I had a problem with the cruise on our '06 Ranger and it turned out to be the module. It acted a bit the same way in that it would set sometimes, other time not. I don't know if the two systems are similar or not.

My cruise fails to engage, sometimes first thing in the mornings, sometimes in the afternoon, cold engine or warm, fresh start or on resume. After the car is turned off for a few, something is resetting it and it then works fine. Wondering if this has something to do with a faulty switch, fuse, or whatever. I've tried the cruise switch on the stalk in turning it off for a while, keeping it pressed in, turning it back on, everything.

I have a very reliable Mazda 3 2006. For the last month I have had a problem with it refusing to start. I put the key in the ignition, turn it on and nothing. No start, no grinding, no clicking, no sound at all. Got a new battery and it happened again. The second AAA tow guy taught me to start the car by putting it in neutral ( with foot brake and hand brake on) and then start it, which does the trick when it won't start otherwise.
After the new battery and continued problems I asked my mechanic to check the electrical system. He did and said everything was fine.
I don't know whether this is a generator, alternator, computer or battery problem. And I don't know what I am doing to my car when I do the neutral set start. I don't know if I am hurting my car when I do that.
The problem is intermittent. There is no pattern: length of trip before I stop, length of time the car is not used, etc. What is causing this and what needs to be looked at/ fixed.

I've got a '08 F250 XLT that the cruise control has become intermittent. It works most of the time but at times it will "go out to lunch" and not do anything. I've taken the controls from the wheel and didn't see any gummed up coke spills or anything there. It may not be anything but twice when it failed while on a trip I pulled over and shut the truck down. Started it up and the cruise would go back to working. Once I did this and it went back to working only to shut off in about 2 seconds but I was able to engage it again and it kept working. When it stops working there is no green indicator on the dash either.

F250 6.8L .. So Ive read a lot of posts about intermittent cruise control issues. I understand that the most common failure is the brake switch on the master cylinder. My concern is that I am unable to run the cruise control self test I keep reading about. Does this test not work on my model year. I have tried even when the cruise control is working and still the cc light does no come on.

For the past 4 mornings when leaving for work my compass (not satnav) in the MFD has been wrong. It has only said N or NE regardless of which way I am traveling.
I have about an hour-long trip to work. The car sits for about 4 hours then for lunch IT WORKS. For the trip home IT WORKS. Then the next morning... CRAP. I've tried shutting off the car and restarting first thing and half way through the trip. I've also tried stopping for 20 minutes on the way in.

Curiosity question. I've noticed that on a downhill of a couple miles, especially in "braking" mode or with the cruise control on, the motor/generator and engine are used to keep the speed down and the battery gets charged to the very top quite quickly. That's good!
On a really long downhill, will the motor/generator still be used for braking and the excess electricity discarded to keep from overcharging the battery?

I have a quick question about the control arms on the B5. I have an 01 Passat GLX 4motion, the was previously my mothers. She had the upper arms (iirc) replaced around 60k but not all of them. I got the car with 64k from her, and it now has 92k of mostly highway miles. I have a few clunks from the suspension but nothing crazy, and considering the shocks and dampers are probably shot i cant seem to tell if its the arms or the shocks.

I used to have LED brake lights in my taillights and decide to change them to old regular bulbs. After that Saturday 3am cruise control don't want to work. Then in the morning with all the lights off (headlights turns etc) the cruise works, as soon as I turn the lights on it stop working. I try to see the what's the cruise control fuse in the fuse card but I can't figure out which one is. 99 passat GLS manual trans.

I am looking to remove the entire cruise control system from my passat. Where the cruise control module is and what the cruise control module connects to? i know it needs a signal from the VSS, but what else?

My Cruise control hasn't been working for a while now when i first bought the car it would work when it wanted to... sometimes it would work and sometimes it wouldn't or even sometimes it would work then all of a sudden while its in cruise it would just stop working
Now I want to fix this problem and get it to work again what should i start to look for, what could be some common stuff that I should look for I heard the cruise control is a PITA to fix once they stop working. I don't know much about the cruise control so where i should start and what I should look for first...

About a year ago the cruise control in my 1998 Passat started to work intermittently. Now it is not working at all. I have tried to tap the stalk thinking that something could be loose. I have a 5 speed manual.

I just purchased my 98 1.8t manual and for the most part it was a steal. Only 108k miles. Everything is strong just a few minor things. Right now I want to get my cruise control working. Is there a light in the dash that goes on? What are the fuses related to it? Nothing happens when I turn it on or hold the button to set it. what should I look for?
