C5-R automatic wipers turn off

Unread post by dulenator »

Some time ago I was going through Lexia and I thought I saw somewhere option to set the rain-sensing wiper option to classic intermittent wiping, but now I cannot find that option.
Does this option even exist, or was it just my imagination? :-s

Auto mode is practically useless (probably something to do with the sensor, but I don't plan to touch that) and I would rather have intermittent wiping instead.

I need this for C5 restyle.

Then just use the intermittent setting you already have on the wiper stalk. You should have an AUTO setting, a speed 2, speed 1 and a speed I for intermittent and a 0 for off.

I wouldn't start changing BSI settings or you will affect the auto lighting and also this will affect the climate control system as the sensor is dual purpose as it detects the amount of infra red light which is used for the A/C climate control system.

Does disabling auto wiping in the BSI default the option to intermittent? When I disabled the auto wiping on my Mk1 C5 (I know, not the same) it defaulted to a much more useful flick wipe.

The Mark I is a different setup as it has 2 separate sensors and separate configuration options in the BSI, whereas the MK II has a bisensor. I can't be certain on the impact this will have therefore.

On the stalk I have (down) manual option and (up) 0-Auto-1-2, there is no intermittent option.
I don't know if there is some other option that I don't see besides these on the stalk.
I have one as on the picture.

Ok, so if speed one is not acceptable, then it looks like a down flick for a quick wipe then, or make sure your screen is thoroughly clean with some proper glass cleaner to get all the grease off which may improve the automatic wiping functionality.

Further - if you have had the windscreen replaced or removed the sensor assembly, you may have opaqueness in the sensor gel pad that is causing problems.

So not intermitting for me... 8-[
Maybe it's a silly question but could just a simple stalk swap to the one with the intermittent option make this work?

The windshield is original and the sensor part looks clear. I'm always degreasing that part, but without any result.
It's good to know if there is no solution to this so I can move to the next issue in line. :-D

Next issue :-D

The wiper control units are vehicle specific (they link into the control module underneath the steering wheel), so need to be specific to the vehicle and options.

On my first C5 the auto was broken, probably a defunct rain sensor, and it defaulted to intermittent.

I will definitely skip messing with the wiper control unit thingy. I'm gonna use manual or first speed and enjoy the smooth ride. 8-)
My first car had single-speed wipers and I never complained about that. The older I get, the more grumpy I am. :-D

Thank you all on your replies.

Today, while changing my RD4 N1-something (without MP3) to RD4 N1-something else (with MP3), I went a little bit through the menus and found something interesting.

Could the solution to the automatic wipers be to turn off the rain sensor? Maybe that would create a similar situation myglaren had.

Is it safe to turn this option off, try the auto wiping and then turn the sensor on again if the wipers are not working correctly?
I don't want to change any option that could potentially cause problems and not solve anything.

Just make sure you take a print out or screenshot of the settings/configuration before you change anything. If it doesn’t work out just change it back again.
Only just noticed this thread but to reply to the com2000 question. The com2000 stalks on auto & non auto wiper models are electrically identical so it wouldn’t change anything to do with the wiper options if you replaced with a non auto model.The only difference is the markings printed on the stalk.
On older models you could certainly just disable the function with Lexia & it would default back to timed intermittent. You could also just unplug the rain sensor on older models & this would also make it default back to regular intermittent. Obviously this was only doable on models with a separate rain sensor & not a shared rain & light sensor.

Don't forget this will likely impact on your climate settings too as it's a bi-function sensor, so has the following role:
  • The bi-sensor gives information on outside ambient brightness and determines the quantity of water on the windscreen.
  • The bi-sensor also provides information on the infra-red light going to the air conditioning system.
So if you don't mind problems with the Climate operation or the auto wipers...

Well damn sensors. :whip1:
Then it stays as it is and I will remain the intermittent human switch.

Thank you for your replies and I will not get back to this anymore. :---) :mrgreen:

I'm just pointing out the possible implications so you can at least make an informed choice before you do anything.

There will be a cause for this and I suspect it is the control module under the steering wheel / stalk contacts or control causing the issue, but really needs further investigation. Just be wary of taking this off as the clockspring mechanism is sensitive and can be easily damaged, and if removed will likely need the Steering Wheel Angle Sensor calibration done after replacing it.
