Brake Servo Defect

[cwcarruthers]

A few times on startup my MFD has shown a warning:

Brake Servo Defect

It disappears quite quickly. Once the message was also accompanied by a chime.

The brakes feel like they are working fine, and I had Essendon Volkswagen check it out. They did only a very quick visual check and said there was nothing wrong, it was safe to drive. I have however booked it in to get a proper check done just to be safe.

The only other thing is the brakes do make a noticable noise at very low speed - the last 5km/h -> 0km/h I can hear them make a ssshhhhh noise, like the pads on the rotors. This is not obviously bad though and may be unrelated and normal - does anyone else have this noise?

Anyway, in general has anyone seen the error on their Mk VI? Any advice?

Thanks.

When it comes to the only things that stop your car, I would get this looked at (maybe even towed) ASAP by Volkswagen...

You can imagine I'm a bit stuck, when naturally I'm pretty conservative about these safety things and was thinking like you, but when Volkswagen use the term "safe to drive", what am I supposed to do?

I guess the thing keeping me not too worried is that the car feels absolutely fine, pulls up strong and importantly, consistently. Maybe this is foolish...

Get it in writing from the Service Manager, otherwise it's your word against their's if anything goes wrong.

Just keep driving it, and if you run into the car or wall in front of you you'll know it's time to get it looked at again.

At the very least you should be able to do a visual inspection yourself to see if the pads and rotors are in good condition (may need to remove your wheels) and also keep an eye on the brake fluid levels.

If you're still getting no joy from Volkswagen and you are still concerned, then take your car to a brake specialist (or independent VW specialist) so they can have a gander as well.

If there really is a fault with the brake servo and it stops giving you power assist you will find that the brakes need a MUCH harder push on them to slow you down, so it would be prudent to leave yourself a bit extra braking distance just in case.

I find it slightly odd that the mechanic who "checked" your car didn't hook up the dealer software tool to see if any fault codes were stored.

That Brake Servo Defect on the MFD appeared once for me, maybe 3-4 weeks ago (in a less than 5 week old Golf), right after the key was inserted and turned; and similarly disappeared quickly. Freaked me out, but hasn't shown up since (although I haven't been actively looking for it) so I haven't done anything about it. o.0
My brakes seem to be working fine, and no obvious unusual noises..

Let us know how you go with resolving this issue =]

I am not sure is it related but there is something on this German (mentioned in some other treads) web-site:

That's some good detective work. So it may just be an incorrectly displayed message.

Good link Mirsad, Thanks.

Here is is again with the translation done. VW Golf VI - typical faults and problems, recalls

Also clarifies the 6-speed DSG recall somewhat. Seemingly less than 5% of the recalled cars actually need the software update, but being done to the lot to be sure, to be sure.....
