AA removed motor which was cracked and looked corroded so i could drive home.

Am on a budget and dont have funds to go to VW, what are my options and where is the cheapest to get the parts?
Yes my rear passenger side EPB failed as well and had to get brake down recovery to take it to my friends garage. Lucky I had warranty and got it replaced. Cost me £50 excess

I have used this method (once in the nine years of my ownership of this '06MY) and it does perform a "hard reset" of the EPB control module.
It may work for you:
Disconnec the battery for 10 minutes then reconnect again. (you will get steering wheel and traction control icons on your dash when you drive off but these will clear after a few hundred yards)
Press the footbrake for 35 seconds, then whilst continuing to press the footbrake, press in and hold the EPB button in for 10 seconds, start the car, (still holding in the button and foot on brake).
The car’s computer will restart and the problem might be (temporarily) fixed.

This is also a useful procedure to use after changing the EPB switch if faults don’t immediately clear.

Worth a try? Can't hurt

I've put together a small help .doc detailing options and other info for fix in case it helps someone (my memory ;-)
So PM me an email address for return attach \:D/

Apart from the above that resets the controller, there's no quick fix except to change the calliper complete with EPB
Sent the help .doc in email to you just now

Thank you for the email, a big help. Because of todays weather of being rain, I only managed to take off the caliper 2 bolts, so later I can release the caliper, and turn it around to undo the t30 torex bolts.

Now the caliper is tough to take off, any suggestions, but in the document it mentions a t45 torex bolt or screw to undo 360 degrees clockwise to release the brake pads. I am having difficulty on finding this, the only 2 torex heads I can see is for the actual electronic motor housing. Could you please shed some light on this. I really need to get my car back on road. Any pictures will help.
Kind regards

If you have no VCDS available then you can undo the torx bolt max one turn. I say max one turn 360º because if you do more the pads will be outside the electronic controller's re-setup range. It's a T45 in the middle that winds the pads back. I've never done this coz I have VCDS and so used that and didn't take a specific pix.

There's many threads listed in the URLs in that .doc. One of them must have a pix with the T45 showing?
The T45 is between the two calliper holding bolt heads -- ISTR

Okay my rear passenger side motor is on its way out and shows fault code too , so ordered a brand new TRW motor only .

Is it just the two allen type bolts to the caliper and then perform the reset proceedure .


Mine is a very early 2005 b6 so looks to be the 6 spline torq inside the motor as they are different for like 2008 onwards .

Anything else to mention to mechanic ? ( needed one as close to my house as possible ! )

Can most mechanics computers do the brake reset thing or does it have to be vcds????

For the sake of a few quids more you could've saved yourself some grief by changing over to a complete caliper.
Still, that was then, this is now. Get yourself a copy of my help .doc. PM me an email address for return attach. It has both methods detailed.

As you're changing out the motor only then VCDS will be needed to re-adapt the EPB module to its datum state with your current pads' thickness

I picked up my 3.2 4Motion last Friday, it has been fine on the test drive, a week before, but on the way to work the EPB error came on the dash. I thought it was the dreaded motor failure, but it appears to just be an intermittent switch failure, so I've got one on order. Having read about the motor failing I think I might look out for one from a breakers yard as a back up too, seems its inevitable.

The system was revised to correct flaws in the casing design i believe.

Think the first 2 - 3 years production occurred then thre redesign and the later revision is less prone to failure.

Thats why earlier and later epb controllers and parts are incompatible iirc

Hi newbie here, needed a question answered on this subject if poss. I have an EPB fault which is no power at driverside caliper thus the brake does not come on, luckily I'm still able to use it. My question is this when scanning this module via obd it comes up as 3C0.907.801.G but the actual module ends with B??? Want to replace the module but don't know whether to order a B or G? Passenger side still works fine. Have tried a new button but no good 😞
Thanks

B6 EPB TRW (Electric park brake) £36.99 ebay.
For the past week i've had the flashing dash and audible warning. I managed to free the caliper so i could get to and from work. DON'T GET COUGHT OUT, YOU ONLY NEED A T30 & T50 TORX TOOL.

Easy diy fix without the need for vcds

If your brake has locked on and cant move do this:
1, jack car and chock front wheels
2, remove wheel
3, remove x2 torx bolts T30 each side of motor
4, pull motor from caliper and unclip plug
5, Unwind plate (clockwise) to free pads with T50 torx where the drive cog fits then tap piston from the pad side to free up
6, refit motor to get mobile but don't use. park in gear.

New part arrival: prep car as above.
1, make sure plate where motor fits T50 is wound out (clockwise) till stops.
2, replace dust seal if required 47mm x 3mm
3, plug motor in and locate unit into the T50 hole then tighten x2 T30 torx
4, make car safe to drive.

Dash & brake light were still lit on ignition, operated switch with foot brake and lights went out along with audible over 10mph. Motor resets itself due to winding out the T50 plate.

Total time 40mins (My diy repair of the motor lasted 4yrs)

Other then a seizing calliper/dash warning is there any clues that a motor is about to fail?

The reason I ask is my drivers side rear alloy is pretty dusty (looks like brake dust to me, reddish black/brown colour), where as the other alloys are pretty clean?

Thanks in advance ^:)^

How quickly the hold and release works and how noisy it is, a clogged motor and gears are slower and noisier.

Proper operation is quite quiet and quick.
