Thanks for that info Dezzy. It sounds about right for a '96 not to have the intermittent delay switch on the stalk (our other family A8 QS 4.2 hasn't got one) But, I'd have thought a '98 M~Y car would have the switch. I'm certain that my Jan '98 3.7 Q registered company car had this fitted. Having a look at the steering wheel plastic shrouds on my project car, it looks like someone has at sometime removed them (one screw missing) I wouldn't be surprised if the windscreen wiper switch has been replaced. The wiper stalk looks to be a slightly different colour to the other stalks too.

It's not the end of the world, in spite of what millions thought I'd be interested to know if an upgrade can be done without adding too many new wires, I'm not a very good sparkey.

So how does the VW programmable relay work then Dezzy? Might be an option. Mind you, at the moment there is no sign of life from the stalk switch, so it looks like I'll be forced to replace it.

Well A8Parts will help with a replacement stalk if you need one.

The programmable relay works by turning the int wipers on, let it wipe once and return the stalk to off, then it's on a timer so when you need to wipe again just turn them on and it remembers the time between wipes. From 1 to 22 seconds i think

Thanks for that info once again Dezzy, It would seem to me that the relay would be of more use than the rotary switch, which always seems to select either too much windscreen wiper action or too little, but never quite just enough. Sorry to pester, but do you have the VW part number?

Cheers for that Dezzy. I'll get one off fleabay and enjoy the mod Looks like I still need to buy a new stalk but this sites sponsers can help out there I'll be putting together a list of 'parts required' over the neax couple of days.

Once again Dezzy Thank You for your help

I'm pretty sure the timing set by the switch also varies with road speed too, though personally I'd rather control it that way than the variable relay process.
However, to get to the point I want to make, I'd be making sure it worked "as advertised" before going down that route. Though if you do have to replace the relay anyway that's probably easier and cheaper than the stalk......
