the one fitted now is 90 494 187

That one is for wiper stalk with intermittent wheel

the wipers sweep every 1.5 seconds

If no variable stalk fitted, that`s about right

[Entwood]

I am curious as to What is the usual time  delay for the standard non variable  intermittant  sweep before the VW99 mod is made?

As the OP on this thread I asked the question of upgrading because on the first position (intermittant )  the wipers sweep every 1.5 seconds .

I am thinking this is way to fast & must be  incorrect /a fault 

When I recently brought the car there was no intermittant wipers working  at all. That first position of the switch did nothing . Then on speeds 1 & 2 they would not "park" , but just stop wherever you switched off.

Changed the tall yellow relay  & wipers now park fine but intermittant sweep time is as above ( only a 1.5 sec delay )

Does anyone know the part No. for the correct yellow relay. the one fitted now is 90 494 187 .

  :-[can't check the number of the old one that was in the car when I got it  as SWMBO chucked it out in the rubbish   

TIA   Al

If memory serves that was what I had before fitting the 99 relay. The old 2.5 had the rheostat which was good, but the "fixed" interval of the 3.2 annoyed me immensely, so the 99 relay is a godsend.

You will get very little delay if you have the timer/relay for the older style stalk with the newer stalk since the old stalk adds resistance to extend the interval.

You can change a resistor in the module to increase the delay, get the correct part which gives you a longer fixed delay, change the stalk of fit a "99" variable relay.

There were plentiful supplies of the "99" relay on Ebay when I bought mine. Must fit it some time  (it's going in the Westfield, which has no intermittent wipe currently).

Hardly any delay at all Kevin.  I said 1.5 secs , but its even less than that actually. 

There still  seems to be plenty of "99's"  on  e bay around the £10 mark . So will order one of those
