Whilst poking round with VCDS earlier, I was looking in the ABS module, and noticed a feature called "Brake Disc Wiper".

 

The descriptive text (provided by VCDS) suggests this is a feature of the ABS module that - when the windscreen wipers are active - periodically exerts "minimum brake pressure" on the brake pads to wipe the discs of water.

 

Looks like it can be enabled or disabled, and was set to enabled by default (and that's how I left it).

 

Another little feature I'd not heard of before, thought it might be of interest

 

Are you 100% sure? Because it's unthinkable what could happen if a fault occured and it applied maximum brake pressure.

Yeah it's a VW/Audi thing, been discussed on here before but don't think there was a definitive answer as to if Yetis had it or not.

Hi Anzio, I'm with you on that post.

Just another electrical system liable/able to malfunction.

Are you guys members of the Flat Earth Society by any chance?

What!, cars with new fangled safety devices. We're Doomed.

Has to be like that too, as one cannot apply slight brake pressure with the brake pedal whilst driving forward with one's foot on the throttle to DRY YOUR BRAKES (as the sign used to suggest) as the throttle is immediately closed.

I seem to recall that some Mercs had this feature, nothing that would worry me.

It seems to be fitted to lots of modern cars, not just VAG.

 

Get in and drive and enjoy it.

My memory of the sign was that it said "TRY YOUR BRAKES". Obviously don't throw the anchor out whilst being followed, but a brief brake test is enough to both clear the discs and reassure yourself they still work.

Traction control and stability control have been applying your brakes without your consent for years

I was always under the impression that disc brakes were self cleaning. Unlike drums ! You only had to see a puddle with drum brakes and you had to drive with your foot gently waming the brakes to dry them out. Ah the good old days !

Not !!!
