[Vwdiesel] HELP! '01 Golf annoyingly persistent codes

[Rolf Pechukas]

OK

3 persistent codes I can't get rid of -

- engine light for GP circuit;

- washer fluid light (!);

- ABS light

so I went to the local VW mechanic yesterday and had him supposedly  
fix the issues (except ABS) and clear the codes

he supposedly did the jumper trick on the GP circuit to 'fool' the  
sensor into seeing no differential, and cleared that code, but that  
lasted about 1/2 a minute
as soon as I drove down the road, eng lt came back on

washer fluid fix lasted a little longer - overnight - he said he had  
to clear some stuff bottom of the reservoir and reset the code
but fluid is topped up and I have light again this morning

(man I miss my Rabbit)

the ABS apparently needs the front right wheel speed sensor
an recommendations on where to purchase?
any thoughts about GP or washer circuits?

thanks
