Parking brake fault

[Sandman333]

Several times lately I gave gotten an alarm and dash warning if a parking brake fault. Obviously the brake doesn't engage when I get the fault message. I have almost 67 K miles on the car now. Shutting the car off and restarting or at least inserting the key to accessory temporarily fixes it.

Any TSBs on this? Could this simply be an early warning that my pads need replaced (still on original, 6MT)? Known issue?

I want to say there is something about a parking brake switch or similar, not 100% sure. I'm sure someone else will confirm or deny that, but, by any chance, is there anything wrong with your auto hold button? If that's messed up, it could cause that fault. Check to see if that works or not.

more than likely, you need a new parking brake switch... it's about $50

[Sandman333]

Actually auto hold has been working just fine. Are you talking about the dash switch? If so I can just use auto hold most of the time so that the brake is automatically applied every time I shut the car off until I can get it replaced.

[BsickPassat]

yes, the dash switch. I dunno about the auto-hold that reverts to the parking brake... haven't tried it. Cycling the ignition on/off was what I did when I had this issue

[Incrementalg]

You'll want to replace the switch before you get stuck with the brake on.

[Boosted2003!]

Pretty much every B6 Passat and early CC's have revision A or B switch which are known to fail. I have revision C switch now.

[EVANGELIONHD]

So the problem here is just the switch? Now they makes sense I have that same warning once in a while, and I have noticed that depressing the switch/button in a fast way increases the changes of getting the warning...

So ill be ordering a new switch too..

Part number any one?

If you can wait about a week, you can get them here on eBay from the UK for roughly $38US:

Using Auto-Hold should get you around the faulty switch till you get it replaced. Just make sure your seat belt is on and AH will release the parking brake automatically when you put the car in gear or start to release the clutch. Actually you don't even need AH to release it, should be automatic anyway, but you will need AH to set the brake without the switch.

Got my Vag-Com order, looks like you guys were right. Switch is on its way but the eBay seller was a little slow to ship...

I just got mine from the eBay seller and it took about 7 days to receive it. Installed in less than a minute and works perfectly. You can definitely feel a difference when pushing the button on the new revision. Hard to explain but it's more smooth and less of a snap/click when pressing it.

[buckeyeb03]

Thanks, you guys are great. How difficult/ how do you replace this switch?

To replace the switch, take off the fuse box panel on the drivers side/next to the switch...Push the switch out from the back....Disconnect the plug...Plug new switch in and reinstall.

[Sandman333]

Got the switch replaced today. So far so good. Thanks.

[Sandman333]

Fault has returned, and seems to be getting worse... now what?

[BsickPassat]

Now it's possibly one of the parking brake motors

[Sandman333]

I posted over in the Vag-Com forum. The error found was electrical in the parking brake switch circuit. Possible I got a bad switch as a replacement? Could it be that my rear pads are so worn that this is causing the error? (70K miles on them and they are near the end of their life. I have new ones here)

70k miles on those pads? What?

Dealer replaced mines at 30k miles!7

Yep, almost. Last trip to the dealer for recalls they recommended replacing them. I bought this car new and have just shy of 69,200 on her now, so I rounded up. The remaining pad would certainly make it another 800 miles anyway. Maybe they lasted so long because it's a MT? Less braking because of downshifting and no braking against the engine at low speeds like an AT. Front brake pad thickness is still near new.

Had this fault show up once the other day, and havent seen since. Im surprised this is covered by a TSB since its a known issue. Anyone else had problems with door latches?

[N715DP]

I had my parking brake do the same thing as you describe... switch was replaced by dealer at no cost under CPO at about 60K.

I've already replaced the switch though.

I got 62k out my rear pads of my 6mt 2.0t. I am a little curious if the parking brake button is VW OEM deal since you got it from overseas. If it OEM VW part and switch is revision C version then this throws a bit of wrench in my idea.

It looked like the real part, but didn't have the actual VW/AUDI marking on it like the factory part. That's probably the problem.

Old vs new pads:




Now to beat the frozen rotor off the hub.....

Is that about 3-5mm left on old pads?

[Sandman333]

Probably. That's the outside pad. The inside is a little thinner. I think the dealer said they were 2mm. Didn't get the swap done as I don't have a 14mm triple square here. Have to order it, no local tool stores carry them...

Still couldn't get the rotor to budge (yes I removed the torx screw). Sprayed it down with penetrating oil and then made sure to get it off the rotor surface with brake parts cleaner before I put the old pads back on.
