Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

  • EPark brake button fault_temp fix

    I have a 2009 CC Rline 3.6 VR6. I bought it a while ago withChristmas lights all over the cluster.
    One of the faults was park brake. VCDS diag pointed to the switch as beingfaulty.
    Out of curiosity I pulled the switch out and tried to dissect it. I failed todismantle it from the back but by luck pulled off the actual plunging buttonwith the icon. (when all this was happening it never crossed my mind to takepics)
    Under there I found a plastic white spacer which was disintegrated due toheat/oxidation and it was mounted on a LED PCB.
    I soldered dry joints on 4 pins on the PCB,
    removed all the debris from the shattered spacer by tapping the switch upsidedown on the kitchen counter.
    I used a bit of vacuum pipe to make a spacer the pushed the cap back on.
    went to the car and put the switch back in. On start up the park brake errorwas gone, and the system started working.
    I have used it 4 times since last night and still no issues.

    My thoughts on this is that:
    1. if your vehicle is in Victoria or WA 100% your switch is going to fail, thebush/spacer cannot withstand the heat for a long time. how long it lasts I’mnot sure.

    2. If your button fails, buying a second-hand one from the wreckers or eBay isa waste of time and money. just buy a new one or fiddle with your one if you can.

    that's my 2 bobs for the day stay safe team!!

    That's great to hear!

    I think my original PB button (2009 CC) failed a year ago, so I replaced it with a new one from Topran. [Didn't think to try and take the original button apart, just presumed it was faulty!]

    Anyway, a bit later on I had a fault again - this time it was the rear park brake motor (insufficient voltage). I also had a problem starting the car, and even though the battery seemed to be okay, the RACV replaced it under warranty and the car started straight away. Thing was, no issues with the park brake (6 months ago) since the replacement battery was installed. Thinking the park brake motor issue and maybe even the PB button issue were battery related?

        Not the same switch as a Tiguan.

        Replacement switch from VW is a revised part number.

                I'm going to add to this knowledge bank. For the latter CC models with a lever style ebrake switch (with chrome trim) I found this on Ali Express and Ebay after a bit of digging
