130 TDi Sport - rain sensing wipers as std?

[fraser33]

I'm not sure, I'll try and have a look tonight if I can.

If there is a rain sensor there, do you think the arm would still have the interval timing adjustment mechanism on it, but just not be connected?

Is it definitely an intermittent timer adjustment? I'm asking this because some other manufacturers who fit auto wipers fit what looks like an intermittent timer adjuster, but it is actually a sensitivity adjustment for the auto wipe function. If your car has the black disc on the screen behind the mirror as Snapdragon stated, you definitely have auto wipe. If this is the case, putting the wiper stalk into the intermittent wipe position will not operate the wipers intermittently, it turns on the auto wipe, possibly giving one sweep of the wipers only, if the screen is dry. To test the auto wipe (if fitted), turn them on as described, then spray a small amount of water on the outside of the screen, directly onto the black disc, using a spray bottle or similar. The wipers should then operate until the screen is dry in front of the sensor. They will possibly operate intermittently to start with, but if you continue spraying the sensor, the wipers will gradually speed up to max. Hope this helps, it may be the reason for the problem with your intermittent!

The adjuster on the stalk adjusts the intervals on basic wipers and sensitivity on those with rain-sensitive intervals.

Note that these are not automatic wipers, they are not like those on most cars such as BMW, Renault, Peugeot. The VW ones need to be manually turned on when it rains and will not restart automatically with subsequent showers, they do not sense it start to rain and turn on, they just change speed/interval with the amount of rain and your road speed when the stalk is in the intermittent position.

Perhaps I'm mistaken, I just assumed the adjuster was for intermittent timing. There is a black circle on the screen behind the rear view mirror, but I'd thought this was just where it was stuck to the screen. I'll do the test method, but I'm sure i've had the stalk set in the 'intermittent' position during rain, and nothing happened.

Don't suppose there's a way of finding out if it's the sensor or the relay which is knackered? The dealer quote for the relay (assuming it's a sensor one that's required) was about £30 + VAT.

Also, is the relay under the bonnet, or do I remember reading somewhere it's above the pedals in a hard-to-reach place? I must get a Haynes manual sometime!
